The adjective is derived from Late Middle English habitual (“of one's inherent disposition”), from Medieval Latin habituālis (“customary; habitual”), from Latin habitus (“character; disposition; habit; physical or emotional condition; attire, dress”) + -ālis (suffix forming adjectives of relationship); analysable as habit + -ual. Habitus is derived from habeō (“to have; to hold; to own; to possess”) (possibly ultimately from Proto-Indo-European *gʰeh₁bʰ- (“to grab, take”)) + -tus (suffix forming action nouns from verbs). The noun is derived from the adjective.
Commonly used both attributively before a noun and predicatively after a linking verb.
