Overview
Adjectives of the first and second declension agree with their nouns in gender, number and case, and many term-elements of Greek origin correspond to first- and second-declension nouns. This topic covers these adjectives and their suffixes, the first declension, Greek term-elements and drills.
Adjectives of the first and second declension
Adjectives in the first and second declension change in gender, number, and case.
These adjectives agree with the nouns they modify in gender, number, and case but differ in endings. This is called a coordinated attribute.
Some adjectives can be used as nouns: rectum, caecum, arachnoidea, and vagus.
