dive

dive: [OE] Old English dyfan ‘dive’ came from a prehistoric Germanic *dūbjan. This was a derivative of the base *d(e)ub-, a variant of which, *d(e)up-, was the source of English deep and dip. The colloquial use of the noun for a disreputable bar, nightclub, etc, which comes from 1880s America, is probably a reference to someone ‘diving’ out of sight into such an establishment, which was often in a basement.
=> deep, dip

dive (v.)

mid-13c., from Old English dufan "to dive, duck, sink" (intransitive, class II strong verb; past tense deaf, past participle dofen) and dyfan "to dip, submerge" (weak, transitive), from Proto-Germanic verb *dubijan, from PIE *dheub- "deep, hollow" (see deep (adj.)). Past tense dove is a later formation, perhaps on analogy of drive/drove. Related: Diving. Dive bomber attested by 1939.

dive (n.)

c. 1700, from dive (v.). Sense of "disreputable bar" is first recorded American English 1871, perhaps because they were usually in basements, and going into one was both a literal and figurative "diving."
