behavior

Definition

Human conduct relative to social norms.

Etymology

From Middle English behavoure, behaver, from behaven (modern behave), with the ending apparently in imitation of havour (see 'havior), a corruption of Old French aveir and/or avoir (“a having”), ultimately from Latin habēre. Compare Scots havings (“behavior”), from have (“to behave”). Replaced Old English ġebǣru.
