Pronunciation

  • /bɪˈliːvəbl̩/, /bi-/[1]

Etymology

It is formed from English believe + -able,[2][3] first as bilevable[4] or belevable,[5] modelled on Latin crēdibilis (“credible”).[2] Believe is from Middle English bileven, from Old English belyfan (“to have faith or confidence”).[3]

Earliest recorded meaning

Able to be believed, credible: before 1382, in the early version of the Wycliffite Bible, where Psalm 92 has beleeuable for Latin credibilia.[2][4] The Middle English Dictionary glosses this use as "trustworthy".[4] Etymonline dates the word to the late 14th century.[3]

Semantic evolution

Johnson (1755) defined it as "credible; that which may be credited or believed".[6] From 1892 it was used of works of fiction and their characters, settings or plots, for "convincing, realistic",[2] and Merriam-Webster Unabridged also gives it the sense of inspiring trust or acceptance, as of an actor's portrayal.[5][7]
