From French -able or Latin -abilis; originally found in words only from these forms but later used to form adjectives directly from English verbs ending in -ate, e.g. educable from educate; subsequently used to form adjectives from verbs of all types (influenced by the unrelated word able), e.g. bearable, saleable
- The suffix –able is not etymologically connected with the word able; the suffix is from French –able and Latin –ābilis; the word able is from Old French hable, from Latin habilis ‘handy’, from habere ‘to hold’.
- Some derived adjs are of Germanic origin (e.g. unspeakable, doable), or of Romance origin but not connected with French (e.g. praisable, prayable).
- It can often be attached to verbs ending in -ate (e.g. educable), or to bases that can be both verbs and nouns (e.g. saleable, marriageable, changeable, debatable, rateable).
- It is often confused with the adj suffix –ible. Opposite adjs are often un…able; also common are in…able adjs; remember these only two exceptions recorded in the OALD and CALD: unfeasible, unintelligible (not unfeasable or unintelligable).
- It can also be attached to prepositional verbs, e.g. (un)come-at-able, (un)get-at-able, laugh-at-able, unputdownable. Most of these terms are now dated, very uncommon, and informal.
