About This Book

A concise, school-oriented Latin grammar begins with an introduction to the language's Indo-European origins and then treats sounds, accent, and vowel quantity before explaining noun and adjective declensions, verb conjugations, pronouns, and particles. It covers word formation and compounding, followed by a detailed syntax section on sentence types, clause structures, moods, indirect discourse, and the uses of cases. A prosody unit addresses verse structure and meters, while supplements supply the Roman calendar, naming conventions, rhetorical figures, and indexes to examples and principal verb forms. The text aims to present essential rules clearly for secondary and undergraduate study.

vinculum for earlier vinclum.

So perīculum, saeculum.

4. Syncope. Sometimes a vowel drops out by syncope; as,—

ārdor for āridor (compare āridus);

valdē for validē (compare validus).

CONSONANT CHANGES[10]

8. 1. Rhotacism. An original s between vowels became r; as,—

arbōs, Gen. arboris (for arbosis);

genus, Gen. generis (for genesis);

dirimō (for dis-emō).

2. dt, tt, ts each give s or ss; as,—

pēnsum for pend-tum;

versum for vert-tum;

mīles for mīlet-s;

sessus for sedtus;

passus for pattus.

3. Final consonants were often omitted; as,—

cor for cord;

lac for lact.

4. Assimilation of Consonants. Consonants are often assimilated to a following sound. Thus: accurrō (adc-); aggerō (adg-); asserō (ads-); allātus (adl-); apportō (adp-); attulī (adt-); arrīdeō (adr-); afferō (adf-); occurrō (obc-); suppōnō (subp-); offerō (obf-); corruō (comr-); collātus (coml-); etc.

5. Partial Assimilation. Sometimes the assimilation is only partial. Thus:—

a) b before s or t becomes p; as,—

scrīpsī (scrīb-sī), scrīptum (scrīb-tum).

b) g before s or t becomes c; as,—

āctus (āg-tus).

c) m before a dental or guttural becomes n; as,—

eundem (eum-dem); prīnceps (prīm-ceps).

PECULIARITIES OF ORTHOGRAPHY.

9. Many words have variable orthography.

1. Sometimes the different forms belong to different periods of the language. Thus, quom, voltus, volnus, volt, etc., were the prevailing forms almost down to the Augustan age; after that, cum, vultus, vulnus, vult, etc. So optumus, maxumus, lubet, lubīdō, etc. down to about the same era; later, optimus, maximus, libet, libīdō, etc.

2. In some words the orthography varies at one and the same period of the language. Examples are exspectō, expectō; exsistō, existō; epistula, epistola; adulēscēns, adolēscēns; paulus, paullus; cottīdiē, cotīdiē; and, particularly, prepositional compounds, which often made a concession to the etymology in the spelling; as,—

ad-gerō or aggerō; ad-serō or asserō;
ad-liciō or alliciō; in-lātus or illātus;
ad-rogāns or arrogāns; sub-moveō or summoveō;
and many others.

3. Compounds of jaciō were usually written ēiciō, dēiciō, adiciō, obiciō, etc., but were probably pronounced as though written adjiciō, objiciō, etc.

4. Adjectives and nouns in -quus, -quum; -vus, -vum; -uus, -uum preserved the earlier forms in -quos, -quom; -vos, -vom; -uos, -uom, down through the Ciceronian age; as, antīquos, antīquom; saevos; perpetuos; equos; servos. Similarly verbs in the 3d plural present indicative exhibit the terminations -quont, -quontur; -vont, -vontur; -uont, -uontur, for the same period; as, relinquont, loquontur; vīvont, metuont.

The older spelling, while generally followed in editions of Plautus and Terence, has not yet been adopted in our prose texts.



PART II.



INFLECTIONS.



10. The Parts of Speech in Latin are the same as in English, viz. Nouns, Adjectives, Pronouns, Verbs, Adverbs, Prepositions, Conjunctions, and Interjections; but the Latin has no article.

11. Of these eight parts of speech the first four are capable of Inflection, i.e. of undergoing change of form to express modifications of meaning. In case of Nouns, Adjectives, and Pronouns, this process is called Declension; in case of verbs, Conjugation.



CHAPTER I.—Declension.

A. NOUNS.

12. A Noun is the name of a person, place, thing, or quality; as, Caesar, Caesar; Rōma, Rome; penna, feather; virtūs, courage.

1. Nouns are either Proper or Common. Proper nouns are permanent names of persons or places; as, Caesar, Rōma. Other nouns are Common: as, penna, virtūs.

2. Nouns are also distinguished as Concrete or Abstract.

a) Concrete nouns are those which designate individual objects; as, mōns, mountain; pēs, foot; diēs, day; mēns, mind.

Under concrete nouns are included, also, collective nouns; as, legiō, legion; comitātus, retinue.

b) Abstract nouns designate qualities; as, cōnstantia, steadfastness; paupertās, poverty.

GENDER OF NOUNS.

13. There are three Genders,—Masculine, Feminine, and Neuter. Gender in Latin is either natural or grammatical.

Natural Gender.

14. The gender of nouns is natural when it is based upon sex. Natural gender is confined entirely to names of persons; and these are—

1. Masculine, if they denote males; as,—

nauta, sailor; agricola, farmer.

2. Feminine, if they denote females; as,—

māter, mother; rēgīna, queen.

Grammatical Gender.

15. Grammatical gender is determined not by sex, but by the general signification of the word, or the ending of its Nominative Singular. By grammatical gender, nouns denoting things or qualities are often Masculine or Feminine, simply by virtue of their signification or the ending of the Nominative Singular. The following are the general principles for determining grammatical gender:—

A. Gender determined by Signification.

1. Names of Rivers, Winds, and Months are Masculine; as,—

Sēquana, Seine; Eurus, east wind; Aprīlis, April.

2. Names of Trees, and such names of Towns and Islands as end in -us, are Feminine; as,—

quercus, oak; Corinthus, Corinth; Rhodus, Rhodes.

Other names of towns and islands follow the gender of their endings (see B, below); as,—

Delphī, n.; Leuctra, n.; Tībur, n.; Carthāgō, f.

3. Indeclinable nouns, also infinitives and phrases, are Neuter; as,—

nihil, nothing; nefās, wrong; amāre, to love.

NOTE.—Exceptions to the above principles sometimes occur; as, Allia (the river), f.

B. Gender determined by Ending of Nominative Singular.

The gender of other nouns is determined by the ending of the Nominative Singular.[11]

NOTE 1.—Common Gender. Certain nouns are sometimes Masculine, sometimes Feminine. Thus, sacerdōs may mean either priest or priestess, and is Masculine or Feminine accordingly. So also cīvis, citizen; parēns, parent; etc. The gender of such nouns is said to be common.

NOTE 2.—Names of animals usually have grammatical gender, according to the ending of the Nominative Singular, but the one form may designate either the male or female; as, ānser, m., goose or gander. So vulpēs, f., fox; aquīla, f., eagle.

NUMBER.

16. The Latin has two Numbers,—the Singular and Plural. The Singular denotes one object, the Plural, more than one.

CASES.

17. There are six Cases in Latin:—

Nominative, Case of Subject;
Genitive, Objective with of, or Possessive;
Dative, Objective with to or for;
Accusative, Case of Direct Object;
Vocative, Case of Address;
Ablative, Objective with by, from, in, with.

1. LOCATIVE. Vestiges of another case, the Locative (denoting place where), occur in names of towns and in a few other words.

2. OBLIQUE CASES. The Genitive, Dative, Accusative, and Ablative are called Oblique Cases.

3. STEM AND CASE-ENDINGS. The different cases are formed by appending certain case-endings to a fundamental part called the Stem.[12] Thus, portam (Accusative Singular) is formed by adding the case-ending -m to the stem porta-. But in most cases the final vowel of the stem has coalesced so closely with the actual case-ending that the latter has become more or less obscured. The apparent case-ending thus resulting is called a termination.

THE FIVE DECLENSIONS.

18. There are five Declensions in Latin, distinguished from each other by the final letter of the Stem, and also by the Termination of the Genitive Singular, as follows:—

DECLENSION. FINAL LETTER OF STEM. GEN. TERMINATION.
First ā -ae
Second ŏ
Third ĭ / Some consonant -īs
Fourth ŭ -ūs
Fifth ē -ēī / -ĕī

Cases alike in Form.

19. 1. The Vocative is regularly like the Nominative, except in the singular of nouns in -us of the Second Declension.

2. The Dative and Ablative Plural are always alike.

3. In Neuters the Accusative and Nominative are always alike, and in the Plural end in .

4. In the Third, Fourth, and Fifth Declensions, the Accusative Plural is regularly like the Nominative.



FIRST DECLENSION.

ā-Stems.

20. Pure Latin nouns of the First Declension regularly end, in the Nominative Singular, in , weakened from , and are of the Feminine Gender. They are declined as follows:—

Porta, gate; stem, portā-.

SINGULAR.
CASES. MEANINGS. TERMINATIONS.
Nom. porta a gate (as subject)
Gen. portae of a gate -ae
Dat. portae to or for a gate -ae
Acc. portam a gate (as object) -am
Voc. porta O gate!
Abl. portā with, by, from, in a gate

PLURAL.
Nom. portae gates (as subject) -ae
Gen. portārum of gates -ārum
Dat. portīs to or for gates -īs
Acc. portās gates (as object) -ās
Voc. portae O gates! -ae
Abl. portīs with, by, from, in gates -īs

1. The Latin has no article, and porta may mean either a gate or the gate; and in the Plural, gates or the gates.

Peculiarities of Nouns of the First Declension.

21. 1. EXCEPTIONS IN GENDER. Nouns denoting males are Masculine; as, nauta, sailor; agricola, farmer; also, Hadria, Adriatic Sea.

2. Rare Case-Endings,—

a) An old form of the Genitive Singular in -ās is preserved in the combination pater familiās, father of a family; also in māter familiās, fīlius familiās, fīlia familiās. But the regular form of the Genitive in -ae is also admissible in these expressions; as, pater familiae.

b) In poetry a Genitive in -āī also occurs; as, aulāī.

c) The Locative Singular ends in -ae; as, Rōmae, at Rome.

d) A Genitive Plural in -um instead of -ārum sometimes occurs; as, Dardanidum instead of Dardanidārum. This termination -um is not a contraction of -ārum, but represents an entirely different case-ending.

e) Instead of the regular ending -īs, we usually find -ābus in the Dative and Ablative Plural of dea, goddess, and fīlia, daughter, especially when it is important to distinguish these nouns from the corresponding forms of deus, god, and fīlius, son. A few other words sometimes have the same peculiarity; as, lībertābus (from līberta, freedwoman), equābus (mares), to avoid confusion with lībertīs (from lībertus, freedman) and equīs (from equus, horse).

Greek Nouns.

22. These end in (Feminine); -ās and -ēs (Masculine). In the Plural they are declined like regular Latin nouns of the First Declension. In the Singular they are declined as follows:—

Archiās, Archias. Epitomē, epitome. Comētēs, comet.
Nom. Archiās epitomē comētēs
Gen. Archiae epitomēs comētae
Dat. Archiae epitomae comētae
Acc. Archiam (or -ān) epitomēn comētēn
Voc. Archiā epitomē comētē (or )
Abl. Archiā epitomē comētē (or )

1. But most Greek nouns in become regular Latin nouns in -a, and are declined like porta; as, grammatica, grammar; mūsica, music; rhētorica, rhetoric.

2. Some other peculiarities occur, especially in poetry.



SECOND DECLENSION.

ŏ-Stems.

23. Pure Latin nouns of the Second Declension end in -us, -er, -ir, Masculine; -um, Neuter. Originally -us in the Nominative of the Masculine was -os; and -um of the Neuters -om. So also in the Accusative.

Nouns in -us and -um are declined as follows:—

Hortus, garden; stem, hortŏ-. Bellum, war; stem, bellŏ-.
SINGULAR.
TERMINATION. TERMINATION.
Nom. hortus -us bellum -um
Gen. hortī bellī
Dat. hortō bellō
Acc. hortum -um bellum -um
Voc. horte -e bellum -um
Abl. hortō bellō

PLURAL.
Nom. hortī bella -a
Gen. hortōrum -ōrum bellōrum -ōrum
Dat. hortīs -īs bellīs -īs
Acc. hortōs -ōs bella -a
Voc. hortī bella -a
Abl. hortīs -īs bellīs -īs

Nouns in -er and -ir are declined as follows:—

Puer, boy; stem, puerŏ- Ager, field; stem, agrŏ- Vir, man; stem, virŏ-
SINGULAR. TERMINATION.
Nom. puer ager vir   Wanting
Gen. puerī agrī virī
Dat. puerō agrō virō
Acc. puerum agrum virum -um
Voc. puer ager vir   Wanting
Abl. puerō agrō virō

PLURAL.
Nom. puerī agrī virī
Gen. puerōrum agrōrum virōrum -ōrum
Dat. puerīs agrīs virīs -īs
Acc. puerōs agrōs virōs -ōs
Voc. puerī agrī virī
Abl. puerīs agrīs virīs -īs

1. Note that in words of the type of puer and vir the final vowel of the stem has disappeared in the Nominative and Vocative Singular.

In the Nominative and Vocative Singular of ager, the stem is further modified by the development of e before r.

2. The following nouns in -er are declined like puer: adulter, adulterer; gener, son-in-law; Līber, Bacchus; socer, father-in-law; vesper, evening; and compounds in -fer and -ger, as signifer, armiger.

Nouns in -vus, -vum, -quus.

24. Nouns ending in the Nominative Singular in -vus, -vum, -quus, exhibited two types of inflection in the classical Latin,—an earlier and a later,—as follows:—

Earlier Inflection (including Caesar and Cicero).
Servos, m., slave. Aevom, n., age. Equos, m., horse.
SINGULAR.
Nom. servos aevom equos
Gen. servī aevī equī
Dat. servō aevō equō
Acc. servom aevom equom
Voc. serve aevom eque
Abl. servō aevō equō

Later inflection (after Cicero).
SINGULAR.
Nom. servus aevum equus
Gen. servī aevī equī
Dat. servō aevō equō
Act. servum aevum equum
Voc. serve aevum eque
Abl. servō aevō equō

1. The Plural of these nouns is regular, and always uniform.

Peculiarities of Inflection in the Second Declension.

25. 1. Proper names in -ius regularly form the Genitive Singular in (instead of -iī), and the Vocative Singular in (for -ie); as Vergílī, of Virgil, or O Virgil (instead of Vergiliī, Vergilie). In such words the accent stands upon the penult, even though that be short. Nouns in -ajus, -ejus form the Gen. in -aī, -eī, as Pompejus, Pompeī.

2. Nouns in -ius and -ium, until after the beginning of the reign of Augustus (31 B.C.), regularly formed the Genitive Singular in -i (instead of -iī); as,—

Nom. ingenium fīlius
Gen. ingénī fīlī

These Genitives accent the penult, even when it is short.

3. Fīlius forms the Vocative Singular in (for -ie); viz. fīlī, O son!

4. Deus, god, lacks the Vocative Singular. The Plural is inflected as follows:—

Nom. (deī)
Gen. deōrum (deum)
Dat. dīs (deīs)
Acc. deōs
Voc. (deī)
Abl. dīs (deīs)

5. The Locative Singular ends in ; as, Corinthī, at Corinth.

6. The Genitive Plural has -um, instead of -ōrum,—

a) in words denoting money and measure; as, talentum, of talents; modium, of pecks; sēstertium, of sesterces.

b) in duumvir, triumvir, decemvir; as, duumvirum.

c) sometimes in other words; as, līberum, of the children; socium, of the allies.

Exceptions to Gender in the Second Declension.

26. 1. The following nouns in -us are Feminine by exception:—

a) Names of towns, islands, trees—according to the general rule laid down in § 15, 2; also some names of countries; as Aegyptus, Egypt.

b) Five special words,—

alvus, belly;

carbasus, flax;

colus, distaff;

humus, ground;

vannus, winnowing-fan.

c) A few Greek Feminines; as,—

atomus, atom;

diphthongus, diphthong.

2. The following nouns in -us are Neuter:—

pelagus, sea;

vīrus, poison;

vulgus, crowd.

Greek Nouns of the Second Declension.

27. These end in -os, -ōs, Masculine or Feminine; and -on, Neuter. They are mainly proper names, and are declined as follows:—

Barbitos, m. and f., lyre. Androgeōs, m., Androgeos. Īlion, n., Troy.
Nom. barbitos Androgeōs Īlion
Gen. barbitī Androgeō, Īliī
Dat. barbitō Androgeō Īliō
Acc. barbiton Androgeō, -ōn Īlion
Voc. barbite Androgeōs Īlion
Abl. barbitō Androgeō Īliō

1. Nouns in -os sometimes form the Accusative Singular in -um instead of -on; as, Dēlum, Delos.

2. The Plural of Greek nouns, when it occurs, is usually regular.

3. For other rare forms of Greek nouns the lexicon may be consulted.



THIRD DECLENSION.

28. Nouns of the Third Declension end in -a, -e, , , -y, -c, -l, -n, -r, -s, -t, -x. The Third Declension includes several distinct classes of Stems,—

I. Pure Consonant-Stems.
II. ĭ-Stems.
III. Consonant-Stems which have partially adapted themselves to the inflection of ĭ-Stems.
IV. A very few stems ending in a long vowel or a diphthong.
V. Irregular Nouns.

I. Consonant-Stems.

29. 1. In these the stem appears in its unaltered form in all the oblique cases, so that the actual case-endings may be clearly recognized.

2. Consonant-Stems fall into several natural subdivisions, according as the stem ends in a Mute, Liquid, Nasal, or Spirant.

A. Mute-Stems.

30. Mute-Stems may end,—

1. In a Labial (p); as, prīncep-s.

2. In a Guttural (g or c); as, rēmex (rēmeg-s); dux (duc-s).

3. In a Dental (d or t); as, lapis (lapid-s); mīles (mīlet-s).

1. STEMS IN A LABIAL MUTE (p).

31. Prīnceps, m., chief.

SINGULAR. TERMINATION.
Nom. prīnceps -s
Gen. prīncipis -is

Nom. prīncipēs -ēs
Gen. prīncipum -um
Dat. prīncipibus -ibus
Acc. prīncipēs -ēs
Voc. prīncipēs -ēs
Abl. prīncipibus -ibus

2. STEMS IN A GUTTURAL MUTE (g, c).

32. In these the termination -s of the Nominative Singular unites with the guttural, thus producing -x.

Rēmex, m., rower. Dux, c., leader.
SINGULAR. PLURAL. SINGULAR. PLURAL.
Nom. rēmex rēmigēs dux ducēs

Voc. rēmex rēmigēs dux ducēs
Abl. rēmige rēmigibus duce ducibus

3. STEMS IN A DENTAL MUTE (d, t).

33. In these the final d or t of the stem disappears in the Nominative Singular before the ending -s.

Lapis, m., stone. Mīles, m., soldier.
SINGULAR. PLURAL. SINGULAR. PLURAL.
Nom. lapis lapidēs mīles mīlitēs

Acc. lapidem lapidēs mīlitem mīlitēs
Voc. lapis lapidēs mīles mīlitēs
Abl. lapide lapidibus mīlite mīlitibus

B. Liquid Stems.

34. These end in -l or -r.

Vigil, m., watchman. Victor, m., conqueror. Aequor, n., sea.

SINGULAR.
Nom. vigil victor aequor
Gen. vigilis victōris aequoris
Dat. vigilī victōrī aequorī
Acc. vigilem victōrem aequor

Dat. vigilibus victōribus aequoribus
Acc. vigilēs victōrēs aequora
Voc. vigilēs victōrēs aequora
Abl. vigilibus victōribus aequoribus

1. Masculine and Feminine stems ending in a liquid form the Nominative and Vocative Singular without termination.

2. The termination is also lacking in the Nominative, Accusative and Vocative Singular of all neuters of the Third Declension.

C. Nasal Stems.

35. These end in -n,[13] which often disappears in the Nom. Sing.

Leō, m., lion. Nōmen, n., name
SINGULAR. PLURAL. SINGULAR. PLURAL.
Nom. leō leōnēs nōmen nōmina
Gen. leōnis leōnum nōminis nōminum
Dat. leōnī leōnibus nōminī nōminibus
Acc. leōnem leōnēs nōmen nōmina
Voc. leō leōnēs nōmen nōmina
Abl. leōne leōnibus nōmine nōminibus

D. s-Stems.

36.

Mōs, m. custom. Genus, n., race. Honor, m., honor.

SINGULAR.
Nom. mōs genus honor
Gen. mōris generis honōris
Dat. mōrī generī honōrī
Acc. mōrem genus honōrem
Voc. mōs genus honor
Abl. mōre genere honōre

PLURAL.
Nom. mōrēs genera honōrēs
Gen. mōrum generum honōrum
Dat. mōribus generibus honōribus
Acc. mōrēs genera honōrēs
Voc. mōrēs genera honōrēs
Abl. mōribus generibus honōribus

1. Note that the final s of the stem becomes r (between vowels) in the oblique cases. In many words (honor, color, and the like) the r of the oblique cases has, by analogy, crept into the Nominative, displacing the earlier s, though the forms honōs, colōs, etc., also occur, particularly in early Latin and in poetry.

II. ĭ-Stems.

A. Masculine and Feminine ĭ-Stems.

37. These regularly end in -is in the Nominative Singular, and always have -ium in the Genitive Plural. Originally the Accusative Singular ended in -im, the Ablative Singular in , and the Accusative Plural in -īs; but these endings have been largely displaced by -em, -e, and -ēs, the endings of Consonant-Stems.

38.

Tussis, f., cough; stem, tussi-. Īgnis, m., fire; stem, īgni-. Hostis, c., enemy; stem, hosti-.

SINGULAR.

TERMINATION.
Nom. tussis īgnis hostis -is
Gen. tussis īgnis hostis -is
Dat. tussī īgnī hostī
Acc. tussim īgnem hostem -im, -em
Voc. tussis īgnis hostis -is
Abl. tussī īgnī or e hoste , -e

PLURAL.
Nom. tussēs īgnēs hostēs -ēs
Gen. tussium īgnium hostium -ium
Dat. tussibus īgnibus hostibus -ibus
Acc. tussīs or -ēs īgnīs or -ēs hostīs or -ēs -īs, -ēs
Voc. tussēs īgnēs hostēs -ēs
Abl. tussibus īgnibus hostibus -ibus

1. To the same class belong—

 apis, bee.  crātis, hurdle. †*secūris, axe.
 auris, ear. *febris, fever.   sēmentis, sowing.
 avis, bird.  orbis, circle. †*sitis, thirst.
 axis, axle.  ovis, sheep.   torris, brand.
*būris, plough-beam.  pelvis, basin. †*turris, tower.
 clāvis, key.  puppis, stern.   trudis, pole.
 collis, hill.  restis, rope.   vectis, lever.
 and many others.

Words marked with a star regularly have Acc. -im; those marked with a † regularly have Abl. . Of the others, many at times show -im and . Town and river names in -is regularly have -im, .

2. Not all nouns in -is are ĭ-Stems. Some are genuine consonant-stems, and have the regular consonant terminations throughout, notably, canis, dog; juvenis, youth.[14]

3. Some genuine ĭ-Stems have become disguised in the Nominative Singular; as, pars, part, for par(ti)s; anas, duck, for ana(ti)s; so also mors, death; dōs, dowry; nox, night; sors, lot; mēns, mind; ars, art; gēns, tribe; and some others.

B. Neuter ĭ-Stems.

39. These end in the Nominative Singular in -e, -al, and -ar. They always have in the Ablative Singular, -ia in the Nominative, Accusative, and Vocative Plural, and -ium in the Genitive Plural, thus holding more steadfastly to the i-character than do Masculine and Feminine ĭ-Stems.

Sedile, seat;
stem, sedīli-.
Animal, animal;
stem, animāli-.
Calcar, spur;
stem, calcāri-.

SINGULAR.

TERMINATION.
Nom. sedīle animal calcar -e or wanting
Gen. sedīlis animālis calcāris -is
Dat. sedīlī animālī calcārī
Acc. sedīle animal calcar -e or wanting
Voc. sedīle animal calcar -e or wanting
Abl. sedīlī animālī calcārī

PLURAL.
Nom. sedīlia animālia calcāria -ia
Gen. sedīlium animālium calcārium -ium
Dat. sedīlibus animālibus calcāribus -ibus
Acc. sedīlia animālia calcāria -ia
Voc. sedīlia animālia calcāria -ia
Abl. sedīlibus animālibus calcāribus -ibus

1. In most words of this class the final -i of the stem is lost in the Nominative Singular; in others it appears as -e.

2. Proper names in -e form the Ablative Singular in -e; as, Sōracte, Mt. Soracte; so also sometimes mare, sea.

III. Consonant-Stems that have partially adapted themselves to the Inflection of ĭ-Stems.

40. Many Consonant-Stems have so far adapted themselves to the inflection of ĭ-stems as to take -ium in the Genitive Plural, and -īs in the Accusative Plural. Their true character as Consonant-Stems, however, is shown by the fact that they never take -im in the Accusative Singular, or in the Ablative Singular. The following words are examples of this class:—

Caedēs, f., slaughter;
stem, caed-.
Arx, f., citadel;
stem, arc-.
Linter, f., skiff;
stem, lintr-.

SINGULAR.
Nom. caedēs arx linter
Gen. caedis arcis lintris
Dat. caedī arcī lintrī
Acc. caedem arcem lintrem
Voc. caedēs arx linter
Abl. caede arce lintre
