Familiar with something through repeated experience or practice; adapted to particular conditions or circumstances. Describes a state of being used to or comfortable with specific situations.
From Old French 'acostumer,' meaning 'to make familiar with,' derived from 'a-' (to) and 'costume' (custom, habit). The word entered English in the 14th century, emphasizing the role of repeated practice in creating familiarity.
The word 'accustomed' reveals how habits literally 'costume' us—they become like clothing we wear so regularly that we forget we're wearing them. Both 'accustomed' and 'costume' share the same root, highlighting how customs and habits shape our identity.
