Cognate with Scots abide(“to abide, remain”), Middle High German erbīten(“to await, expect”), Gothic 𐌿𐍃𐌱𐌴𐌹𐌳𐌰𐌽( usbeidan, “to expect, await, have patience”).

abide (v.)

Old English abidan, gebidan "remain, wait, wait for, delay, remain behind," from ge- completive prefix (denoting onward motion; see a- (1)) + bidan "bide, remain, wait, dwell" (see bide).

Originally intransitive (with genitive of the object: we abidon his "we waited for him"); transitive sense "endure, sustain, stay firm under," also "tolerate, bear, put up with" (now usually with a negative) is from c. 1200. Related: Abided; abiding. The historical conjugation was abide, abode, abidden, but in Modern English the formation generally is weak. Abide with "stay with (someone); live with; remain in the service of" is from c. 1300.
