ADJECTIVES OF THE THIRD DECLENSION 113
LESSON XLV
'ADJECTIVES OF THE THIRD DECLENSION • Ī-STEMS
250. Adjectives are either of the first and second declensions (like bonus, aeger, or līber), or they are of the third declension.
251. Nearly all adjectives of the third declension have i-stems, and they are declined almost like nouns with i-stems.
252. Adjectives learned thus far have had a different form in the nominative for each gender, as, bonus, m.; bona, f.; bonum, n. Such an adjective is called an adjective of three endings. Adjectives of the third declension are of the following classes:
I. | Adjectives of three endings— |
II. | Adjectives of two endings— |
III. | Adjectives of one ending— |
253.
Adjectives of the third declension in -er have three endings;
those in -is have two endings; the others have one ending.
