THIRD DECLENSION (CONSONANT AND i-STEMS)
[*] 53.
Nouns of the Third Declension end in
a,
e,
ī,
ō,
y,
c,
l,
n,
r,
s,
t,
x.
[*] 54.
Stems of the Third Declension are classed as follows:—
I. Consonant Stems
a. Mute stems.
b. Liquid and Nasal stems.
II.
I-Stems
a. Pure
i-stems.
b. Mixed
i-stems.
[*] 55.
The Nominative is always derived from the stem.
The variety in form in the Nominative is due to simple
modi fications of the stem, of which the most important
are—
- Combination of final consonants: as of c (or
g
) and s to form x;
dux
,
ducis
, stem duc-;
rēx
,
rēgis
, stem rēg-.
- Omission of a final consonant: as of a final nasal;
leō
,
leōnis
, stem leōn-;
ōrātiō
,
ōrātiōnis
, stem ōrātiōn-.
- Omission of a final vowel: as of final i;
calcar
,
calcāris
, stem calcāri-.
- Change of vowel in the final syllable : as of a
toe;
prīnceps
(for -caps),
prīncipis
, stem prīncip- (for
-cap-).
CONSONANT STEMS
Mute Stems
[*] 56.
Masculine and Feminine Nouns with mute stems form the Nominative by
adding
s to the stem.
A labial (
p
) is retained before
s: as,
prīncep-s
.
A lingual (
t,
d) is dropped before
s: as,
mīles (stem
mīlit-),
cūstōs
(stem
cūstōd-).
A palatal (
c,
g) unites with
s to form
x: as,
dux
(for †
duc-s
),
rēx
(for †
rēg-s
).
[*] a.
In dissyllabic stems the final syllable often shows
e in
the nominative and
i in the stem: as,
prīnceps
, stem
prīncip-
(for
-cap-).
[*] 57.
Nouns of this class are declined as follows:
[*] a.
In like manner are declined—
-
ariēs, -etis
(M.), ram;
comes, -itis (c.),
companion;
lapis
, -idis (M.),
stone;
iūdex
, -icis (M.),
judge;
cornīx
, -īcis
(F.), raven, and many other nouns.
[*] 58.
Most mute stems are Masculine or Feminine. Those that are neuter have
for the Nominative the simple stem. But,—
[*] a.
Lingual Stems (
t,
d) ending in two consonants drop the final
mute: as,
cor
(stem
cord-),
lac (stem
lact-). So also
stems in
ăt- from the Greek:
as,
poēma
(stem
poēmat-).
[*] b.
The stem
capit- shows
u in
the nominative (
caput for
†capot).
[*] 59.
Nouns of this class are declined as follows:—
[*] 60.
The following irregularities require notice:—
[*] a.
Greek neuters with nominative singular in
-a (as
poēma
) frequently end in
-īs in the dative and ablative plural, and
rarely in
-ōrum in the
genitive plural; as,
poēmatīs
(for
poēmatibus
),
poēmatōrum (for
poēmatum
).
[*] b.
A number of monosyllabic nouns with mute stems want the genitive
plural (like
cor
). See § 103.
g. 2.
Liquid and Nasal Stems (l, n,
r)
[*] 61.
In Masculine and Feminine nouns with liquid and nasal stems the
Nominative is the same as the stem.
Exceptions are the following:—
- Stems in ōn- drop
n in the nominative: as in
legiō
, stem legiōn-.
- Stems in din- and gin- drop n and keep an
original ō in the nominative: as in
virgō
, stem virgin-.1
- Stems in in- (not din- or gin-) retain n and have e
instead ofi in the nominative: as in
cornicen, stem cornicin-.2
- Stems in tr- have -ter in the nominative: as,
pater
, stem patr-.3

[*] Note 1.--Stems in
ll-, rr- (N.) lose one of their liquids in the nominative:
as, far, farris;
mel,
mellis
.
[*] Note 2.--A few masculine
and feminine stems have a nominative in -s as well as in -r: as,
honōs
or honor, arbōs
or arbor.
[*] Note 3.--
Canis, dog, and
iuvenis, youth,
have -is in the nominative.
[*] 63.
In Neuter nouns with liquid or nasal stems the Nominative is the same
as the stem.
Exceptions:
- Stems in in-
havee instead of i in the nominative:
as in
nōmen
, stem nōmin-.
- Most stems in er- and
or- have -us in the nominative: as,genus, stem
gener-.4
[*] 64.
Nouns of this class are declined as follows:—
So also are declined
opus
,
-eris,
work;
pīgnus,
-eris or
-oris,
pledge,
etc.
[*] Note.--The
following real or apparent liquid and nasal stems have the
genitive plural in -ium, and are to
be classed with the i-stems:
imber
, linter,
ūter
, venter; glīs,
mās, mūs,
[†rēn]; also
vīrēs
(plural of
vīs
: see § 79).
i-STEMS
[*] 65.
Nouns of this class include—
- Pure i-Stems:
[*] a.
Masculine and Feminine parisyllabic5 nouns in -is and four in -er.
[*] b.
Neuters in -e, -al, and -ar.
- Mixed i-Stems, declined in the
singular like consonant stems, the plural like i-stems.
Pure i-Stems
[*] 66.
Masculine and Feminine parisyllabic nouns in
-is form the Nominative singular by adding
s
to the stem.
Four stems in
bri- and
tri- do not add
s to form the
nominative, but drop
i and insert
e before
r. These are
imber
,
linter,
ūter
,
venter.
[*] 67.
Nouns of this class are declined as follows:—
[*] 68.
In Neuters the Nominative is the same as the stem, with final
i changed to
e: as,
mare,
stem
mari-. But most nouns
6 in which
the
i of the stem is preceded by
āl or
ār lose the
final vowel and shorten the preceding
ā: as,
animăl, stem
animāli-.
7
[*] a.
Neuters in
-e, -al, and
-ar have
-ī in the ablative singular,
-ium in the genitive plural, and
-ia in the nominative and accusative plural: as,
animal,
animālī
,
-ia,
-ium.
[*] 69.
Nouns of this class are declined as follows:—
Mixed i-Stems
[*] 70.
Mixed
i-stems are either original
i-stems that have lost their
i-forms in the singular, or
consonant stems that have assumed
i-
forms in the plural.
[*] Note.--It is sometimes impossible to distinguish between
these two classes.
[*] 71.
Mixed
i-stems have
-em in the accusative and
-e in the ablative singular,
-ium in the genitive
8 and
-īs or
-ēs in the accusative
plural. They include the following:—
- Nouns in -ēs,
gen. -is.9
- Monosyllables in -s or
-x preceded by a consonant: as,
ars
, pōns,
arx
.
- Polysyllables in -ns or
-rs: as,
cliēns
,
cohors
.
- Nouns in -tās,
genitive -tātis (genitive
plural usually -um)10: as,
cīvitās
.
- Penātēs,
optimātēs
, and nouns denoting birth or abode
(patrials) in -ās, -īs, plural -ātēs, -ītēs: as,
Arpīnās
, plural Arpīnātēs;Quirīs,
plural
Quirītēs
.
- The following monosyllables in -s or -x preceded by a
vowel: dōs,
fraus
, glīs,

Summary of i-Stems
[*] 73.
The i-declension was confused even to the Romans themselves, nor was
it stable at all periods of the language, early Latin having i-forms
which afterwards disappeared. There was a tendency in nouns to lose
the i-forms, in adjectives to gain them. The nominative plural
(-īs)
13 was most thoroughly lost, next the
accusative singular (
-im), next the
ablative (-ī); while the genitive and accusative plural
(
-ium,
-īs) were retained in almost all.
[*] 74.
I-stems show the
i of the
stem in the following forms:—
[*] a.
They have the genitive plural in
-ium
(but some monosyllables lack it entirely). For a few exceptions, see
§ 78.
[*] b.
All neuters have the nominative and accusative plural in
-ia.
[*] c.
The accusative plural (M. or F.) is regularly
-īs.
[*] d.
The accusative singular (M. or F.) of a few ends in
-im (§ 75).
[*] e.
The ablative singular of all neuters, and of many masculines and
feminines, ends in
-ī (see
§ 76).
[*] 75.
The regular case-ending of the Accusative singular of
i- stems (M. or F.) would be
-im: as,
sitis
,
sitim (cf.
stella
,
-am;
servus
,
-um); but in most nouns
this is changed to
-em (following the
consonant declension).
[*] a.
The accusative in
-im is found
exclusively—
- In Greek nouns and in names of rivers.
- In
būris
,
cucumis
,
rāvis
,
sitis
,
tussis
,
vīs
.
- In adverbs in -tim (being
accusative of nouns in -tis), as,
partim; and in
amussim.
[*] b.
The accusative in
-im is found sometimes
in
febris
,
puppis
,
restis
,
turris
,
secūris
,
sēmentis
, and rarely in many other words.
[*] 76.
The regular form of the Ablative singular of
i-stems would be
-ī: as,
sitis
,
sitī; but in most nouns this is
changed to
-e.
[*] a.
The ablative in
-ī is found
exclusively—
- In nouns having the accusative in -im (§ 75);
also
secūris
.
- In the following adjectives used as nouns:
aequālis
,
annālis
,
aquālis
,
cōnsulāris
,
gentīlis
,
molāris
,
prīmipīlāris
,
tribūlis
.
- In neuters in -e, -al, -ar:
except
baccar
,
iubar
,
rēte
, and sometimes mare.
[*] b.
The ablative in -ī is
found sometimes—
- In
avis
,
clāvis
,
febris
, fīnis,
īgnis
,14
imber
, lūx,
nāvis
,
ovis
, pelvis,
puppis
,
sēmentis
,
strigilis
,
turris
, and occasionally in other words.
- In the following adjectives used as nouns:
affīnis
,
bipennis
,
canālis
,
familiāris
,
nātālis
,
rīvālis
, sapiēns,
tridēns
,
trirēmis
,
vōcālis
.
[*] Note 1.--The ablative
offamēs is always
famē(§ 105. e). The defective
māne has sometimes
mānī
(§ 103. b. N.) as ablative.
[*] Note 2.--Most names of towns
in -e (as, Praeneste, Tergeste)
and
Sōracte
, a mountain, have the ablative in -e. Caere has
Caerēte.
[*] Note 3.--Canis
and
iuvenis
have cane,
iuvene
[*] 77.
The regular Nominative plural of
i-stems
is
-ēs,
15 but
-īs is
occasionally found. The regular Accusative plural
-īs is common, but not exclusively used in
any word. An old form for both cases is
-eis (diphthong).
[*] 78.
The following have
-um (not
-ium) in the genitive plural:
- Always,
canis
,
iuvenis
,16
ambāgēs
, mare (once only, otherwise wanting),
volucris;
regularly,
sēdēs
,
vātēs
.
- Sometimes,
apis
,
caedēs
,
clādēs
,
mēnsis
,
struēs
,
subolēs
.
- Very rarely,—patrials in -ās, -ātis; -īs, -ītis; as,
Arpīnās
,
Arpīnātum
,
Samnīs,Samnītum.
Irregular Nouns of the Third Declension
[*] 79.
In many nouns the stem is irregularly modified in the nominative or other
cases. Some peculiar forms are thus declined:—
[*] a.
Two vowel-stems in
ū-,
grū- and
sū-, which follow the third declension, add
s in the nominative, and are inflected like mute stems:
grūs has also a nominative
gruis; sūs has
both
suibus
and
sū˘bus in the dative and
ablative plural,
grūs has only
gruibus
.
[*] b.
In the stem
bov- (
bou-) the diphthong
ou becomes
ō in the nominative (
bōs,
bŏvis).
In
nāv- (
nau-) an
i is added (
nāvis
,
-is), and it is declined like
turris
(§ 67).
In
Iŏv- (=
Ζεύς) the diphthong (
ou
) becomes
ū in
Iū-piter (for
-păter), genitive
Iŏvis
, etc.; but the form
Iuppiter
is preferred.
[*] c.
In
iter
,
itineris
(N.),
iecur,
iecinoris (
iecoris
) (N.),
supellēx
,
supellēctilis (F.), the nominative
has been formed from a shorter stem; in
senex
,
senis
, from a longer; so that these words show a combination of
forms from two distinct stems.
[*] d.
In
nix,
nivis
the nominative retains a
g from the original
stem, the
g uniting with
s, the nominative
ending, to form
x. In the other cases the stem assumes the
form
niv- and it adds
i in the
genitive plural.
[*] e.
Vās
(N.),
vāsis
, keeps
s throughout; plural
vāsa
,
vāsōrum
. A dative plural
vāsibus also occurs.
There is a rare singular
vāsum
.
The Locative Case
[*] 80.
The Locative form for nouns of the third declension ends in the singular
in
-ī or
-ē, in the plural in
-ibus: as,
rūrī,
in the country;
Carthāginī
or
Carthāgine,
at Carthage;
Trallibus,
at Tralles.
18
Greek Nouns of the Third Declension
[*] 81.
Many nouns originally Greek—mostly proper names—
retain Greek forms of inflection. So especially—
- Genitive singular in -os, as,
tigridos
.
- Accusative singular in -a, as,
aethera
.
- Vocative singular like the stem, as,
Periclē
, Orpheu, Atlā.
- Nominative plural in -ĕs, as,
hērōĕs.
- Accusative plural in -ăs, as,
hērōăs
.
[*] 82.
Some of these forms are seen in the following examples:—
|
hērōs, M., hero
|
lampas
, F., torch
|
basis, F., base
|
tigris
, C., tiger
|
nāis
, F., naiad
|
| STEM hērō-
|
STEM lampad-
|
STEM basi-
|
STEM tigrid- tigri-
|
STEM nāid-
|
[*] 83.
Other peculiarities are the following:—
[*] a.
Delphīnus,
-ī (M.), has also the form
delphīn,
-īnis;
Salamīs,
-is (F.) has acc.
Salamīna
.
[*] b.
Most stems in
ĭd- (
nom.
-is) often
have also the forms of
i-stems: as
tigris
, gen.
-ĭdis (
-ĭdos) or
-is; acc.
-ĭdem
(
-ĭda) or
-im (
-in); abl.
-ĭde or
-ī. But many, including most feminine proper
names, have acc.
-idem (
-ida); abl.
-ide,—not
-im or
-ī. (These stems are
irregular also in Greek.)
[*] c.
Stems in
on- sometimes retain
-n in the nominative: as,
Agamemnōn (or
Agamemnō
), genitive
-ŏnis,
accusative
-ŏna.
[*] d.
Stems in
ont- form the nominative in
-ōn: as,
horizōn,
Xenophōn; but a few are
occasionally Latinized into
ōn-
(
nom.
-ō): as,
Dracō,
-ōnis;
Antiphō,
-ōnis.
[*] e.
Like
Simoīs are declined stems in
ant-,
ent-, and a
few in
ūnt- (nominative in
-ās,
-īs,
-ūs): as,
Atlās,
-antis;
Trapezūs,
-ūntis.
[*] f.
Some words fluctuate between different declensions: as
Orpheus between the second and the third.
[*] g.
-ōn is found in the genitive
plural in a few Greek titles of books: as,
Metamorphōseōn,
of the
Metamorphoses (Ovid's well-known poem);
Geōrgicōn,
of the
Georgics (a poem of Virgil).
Gender in the Third Declension
[*] 84.
The Gender of nouns of this declension must be learned by practice and
from the Lexicon. Many are masculine or feminine by nature or in
accordance with the general rules for gender (p. 15). The most important
rules for the others, with their principal exceptions, are the
following:—
20
[*] 85.
Masculine are nouns in
-or,
-ōs,
-er,
-ĕs (gen.
-itis),
-ex (gen.
-ĭcis): as,
color,
flōs,
imber
,
gurges
(
gurgitis
),
vertex (
verticis
).
Exceptions are the following:—
[*] a.
Feminine are
arbor;
cōs,
dōs;
linter.
[*] b.
Neuter are

,
marmor;
ōs (
ōris
); also

-s preceded by a consonant: as,
legiō
,
cīvitās
,
nūbēs
,
avis
,
virtūs
,
arx
,
urbs
. The nouns in
-ō are
mostly those in

in
-iō.
Exceptions are the following:—
[*] a.
Masculine are
leō
,
leōnis;
ligō,
-ōnis;
sermō
,
-ōnis; also
cardō

[*] Note.--Some nouns in -is and -ns which are
masculine were originally adjectives or participles agreeing with a
masculine noun: as,
Aprīlis
(sc.
mēnsis
), M., April;
oriēns
(sc.
sōl
), M., the east;
annālis
(sc.
liber
), M., the year-book.
[*] b.
Neuter are
