Etymology
It is inherited from Middle English incredible,[2][3] borrowed from Latin incrēdibilis (“not to be believed, extraordinary”),[4][5] from in- “not” and crēdibilis (“worthy of belief”),[4][2] the source of credible, from crēdere “to believe”.[4][6] It is related to credit, creed and incredulous.[4]
Earliest recorded meaning
“Unbelievable, surpassing belief as to what is possible”: 1412–20 in the OED,[7] the early 15th century in Etymonline.[4]
Semantic evolution
A now extinct sense, “unbelieving, incredulous”, was used about 1400,[4] 1557 in the OED, and lasted to the mid-18th century.[7][5] The weakened sense, “hard to believe; of exceedingly great quantity or quality, surprising”, is from 1482,[7] now colloquial.[5] As a noun, an incredible thing, it is from 1610.[7] Incredibly is from the late 15th century,[5] and incredibleness from the early 17th.[5][7]
