etymonline
abode (n.)
mid-13c., "action of waiting," verbal noun from abiden "to abide" (see abide). It is formally identical with the old, strong past participle of abide (Old English abad), but the modern conjugation is weak and abided is used. The present-to-preterite vowel change is consistent with an Old English class I strong verb (ride/rode, etc.). Meaning "habitual residence" is first attested 1570s.
