The Latin adjective is divided into two groups and is declined by the pattern of the first three declensions, depending on the generic endings.

NB! The dictionary form of the adjectives of the 1^st group shows their three generic endings in the following order: the full masculine form of the adjective, the feminine ending, the neuter ending: thoracicus, a, um – thoracic. The dictionary form of the adjectives of the 2^nd group shows their 2 generic endings in the following order: the full form of the adjective in masculine and feminine gender, the ending of the neuter gender: vertebralis, e – vertebral. Stem of the adjective is found by dropping the generic ending. The second group of adjectives also includes adjectives of one generic ending, i.e. they don’t vary by gender, their dictionary form includes the adjective itself and its ending in the Genitive case with a part of the changed stem: simplex, icis – simple. The stem of such an adjective is found by dropping the ending -is.

NB! In the Latin term, the definition expressed by the adjective always follows the noun. The exception of this rule is the word mater, tris f, which is preceded by the adjective: pia mater, dura mater.

NB! An adjective always agrees in gender, number, and case with the noun which it defines.

NB! The participles of the active present tense are also declined according to the pattern of declension III, as do the adjectives of the 2^nd group. Such participles do not change by gender, in the dictionary form they have the Gen. sing. ending with a part of the changed stem: ascendens, ntis – ascending, the stem ascendent-.

Lexical Minimum of the 1^st Group Adjectives

NB! The meanings of adjectives are various, they can designate affiliation, consistence, color, location, relation, size, shape, etc. Adjectives of the 1^st group are frequently formed with the suffix -ic- with the meaning of relating to what the stem names, and the suffix -os- with the meaning of consisting of what the stem names.
