Etymology

It is formed from Latin in-2 (“not”) + compatibilis (“compatible”).[2][3]

Earliest recorded meaning

A Canterbury register of 1424 uses it of forged papal letters incompatible with what is genuine.[4]

Semantic evolution

Its chief use was in canon law, of benefices that could not be held together with another office,[4][5][6] and English incompatible (mid-15th century) was first said of benefices too.[3] Hungarian sources also use it for what is contrary or unfitting.[5]
