Adjectives agree with nouns in number and gender. Forms for the nominative and the accusative differ only in the animate gender and even then, only in the singular. For the sake of clarity, the table includes only the endings beginning with ''-a'', but endings can also begin with an ''-i''. The forms are largely derived from the forms of the nominal declension, with an ''-as-'' before the case ending that would be expected for nouns.
