I came across the word "hood", which I haven't seen for a good long time. I realize that it comes from "hoodlum", but the etymology for "hoodlum" seems to be "unknown."
When I was a little girl, the "hoods" were the bad teenagers. I am wondering if "hood" or "hoodlum" might come from "neighborhood"; that is, maybe the bad kids hang around in the same "hood", thus the word "hoodlum"? Does anyone know?
The Word Detective gives a couple of suggestions and debunks them.
I heard that hooligan was of Irish derivation.
OED2 says: "hooligan.
The word first appears in print in daily newspaper police- court reports in the summer of 1898. Several accounts of the rise of the word, purporting to be based on first-hand evidence, attribute it to a misunderstanding or perversion of Hooley or Hooley's gang, but no positive confirmation of this has been discovered. The name Hooligan figured in a music-hall song of the eighteen-nineties, which described the doings of a rowdy Irish family, and a comic Irish character of the name appeared in a series of adventures in Funny Folks."
