often habiliments, early 15c., "munitions, weapons," from Middle French habillement, from abiller "prepare or fit out," probably from abile, habile "fit, suitable" (see able). Alternative etymology [Barnhart, Klein] makes the French verb originally mean "reduce a tree by stripping off the branches," from a- "to" + bille "stick of wood." Sense of "clothing, dress" developed late 15c., by association with habit (n.).
