Old French is traditionally provided with two types of adjectives. Those of Type I descend from the Latin adjectives in -us -a -um, and distinguish the masculine from the feminine by the presence or absence of -e (< -A), e.g. mort < mortu, morte < VL morta; bon < bonu, bone < bona. Those of Type II descend from third-declension adjectives, which do not distinguish the masculine from the feminine, e.g. grant < grande, vert < viride, fort < forte. (The Latin forms are, as is traditional, quoted in the accusative case but without the -M, which was lost before the Proto-Romance era.)
