bide (v.)

Old English bidan "to stay, continue, live, remain," also "to trust, rely," from Proto-Germanic *bidan "to await" (source also of Old Norse biða, Old Saxon bidan, Old Frisian bidia, Middle Dutch biden, Old High German bitan, Gothic beidan "to wait"), which is of uncertain origin. Possibly from PIE root *bheidh- "to trust, confide, persuade" (via notion of "to await trustingly"). Preserved in Scotland and northern England, replaced elsewhere by abide in all senses except in expression bide (one's) time (c. 1840). Related: Bided; biding.
