word-forming element expressing ability, capacity, fitness, from French, from Latin -ibilis, -abilis, forming adjectives from verbs, from PIE *-tro-, a suffix used to form nouns of instrument.
In Latin, infinitives in -are took -abilis, others -ibilis; in English, -able tends to be used with native (and other non-Latin) words, -ible with words of obvious Latin origin (but there are exceptions).
