Etymology

The word "requisite" originates from Latin requisitus, the past participle of requirere ("to seek or ask for again"). The morpheme re- implies repetition, quis derives from quaerere ("to seek or ask"), and -ite serves as a suffix forming adjectives or nouns. Over time, the term evolved to emphasize necessity—something actively sought or demanded for completion.
