Past tense of dive: to plunge headfirst into water or to descend rapidly through air.
From Old English 'dyfan' meaning to dip or immerse. The word evolved from Germanic roots and has been used since around the 900s, originally meaning to dip something into liquid.
In American English, both 'dived' and 'dove' are acceptable past tense forms, but 'dove' (like the bird word) is newer and only became common in the last 100 years, while 'dived' is the traditional form used everywhere else in the English-speaking world.
