Word Origin & History

mid-14c., from O.Fr. (h)able, from L. habilis "easily handled, apt," verbal adj. from habere "to hold" (see habit). "Easy to be held," hence "fit for a purpose." The silent h- was dropped in Eng. and resisted academic attempts to restore it 16c.-17c., but some derivatives
acquired it (e.g. habiliment, habilitate), via French.
"Able-whackets - A popular sea-game with cards, in which the loser is beaten over the palms of the hands with a handkerchief tightly twisted like a rope. Very popular with horny-fisted sailors." [Smyth, "Sailor's Word-Book," 1867]

suffix expressing ability, capacity, fitness, from Fr., from L. -ibilis, -abilis, forming adjectives from verbs, from PIE *-tro-, a suffix used to form nouns of instrument. In L., infinitives in -are took -abilis, others -ibilis; in Eng., -able is used for native words, -ible for words of obvious L.
origin. The Latin suffix is not etymologically connected with able, but it long has been popularly associated with it, and this has contributed to its survival as a living suffix. It is related to the second syllable of rudder and saddle.
