habiliment comes from Middle French habillement ('clothing, equipment'), from habiller ('to clothe, equip, make fit'), originally 'to prepare, make ready', from Latin habilis ('manageable, fit'), from habēre ('to have, hold'). The path is chiefly one of transmission: the word passes through the named languages and forms, with each stage preserving part of the modern shape. In present English, the noun sense is "clothing, especially that suited to a particular role or occasion", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as habilitate, ability, and able. Its semantic neighborhood includes clothing, attire, garb, and apparel, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Middle French habillement and Latin habēre.
