History
* As an English surname, of Norman origin, from Old French roche (“rock”). Compare Roch. * Also as an English surname, from the River Roch; see Roch. * Also as an English surname, shortened from Rochdale.
From Middle English roche, from Old French roche, from Middle Low German roche, ruche (“ray (fish)”), from Old Saxon *rūh, possibly from Proto-Germanic *rūhaz (“rough”). Cognate with Old English ruhha ("a ray"; > Middle English rouhe, rohȝe), German Rochen (“ray (fish)”).
Back-formation from cockroach, as if it were a compound. Marijuana-related meanings by similarity of appearance of the butt, attested since the 1930s.
Apparently from extended or figurative use of roach (“Cyprinidae”), above. Compare the adjective roached (“styled so that the mane stands up from the neck”).
Variant of roche (“rock”). Attested since the seventeenth century.
