Where it comes from
From Middle English behavoure, behaver, from behaven (modern behave), morphologically equivalent to behave + -ior. The suffix was adopted in imitation of havour (modern haviour, havior), an etymologically unrelated word that was corrupted from Anglo‐Norman Anglo-Norman aveir and Old French Old French avoir (“property, wealth”) through false association with the native English verb have. The French term derives ultimately from Latin Latin habēre (“to have, hold”). Compare Scots havings (“behavior”), from have (“to behave”). Replaced Old English ġebǣru.
