Explanation
Four-form adjectives end in -o: alto, alta, altos, altas. Two-form: -e (inteligente/inteligentes), most consonants (difícil/difíciles, azul/azules). Nationality adjectives in consonant add -a: francés/francesa; -or too: trabajador/trabajadora.
With mixed-gender groups, masculine plural wins: un hombre y dos mujeres altos. Plural rules mirror nouns: -s after vowel, -es after consonant, -z → -ces (feliz → felices).
