[*] 117.
The remaining adjectives of the third declension are Consonant stems; but
most of them, except Comparatives, have the following forms of
i-stems:—
1
-
-ī in the ablative
singular (but often -e);
-
-ia in the nominative and
accusative plural neuter;
-
-ium in the genitive plural;
-
-īs (as well as -ēs) in the accusative plural
masculine and feminine.
In the other cases they follow the rule for Consonant stems.
[*] a.
These adjectives, except stems in
l- or
r-, form the nominative singular from
the stem by adding
s: as,
atrōx
(stem
atrōc- +
s
),
egēns
(stem
egent- +
s
).

[*] b.
Here belong the present participles in
-ns
(stem
nt-)
3:
as,
amāns
,
monēns
. They are declined like
egēns
(but cf. § 121).
