I've just watched all six episodes of the BBC historical drama "The Trial of Christine Keeler".

It was marvellous for the way it presented London life of the 1960s - the lovely old cars, the suave John Profumo with a gold cigarette case and lighter, elegant house parties at Cliveden, and the slightly dated idiom and slang.

Christine, at one point says "It's the rozzers…", which took me back in time.

Why "rozzers"?

    @k1eran I was going to add the suggestion that it was linked to Robert Peel then I clicked on your link. I'm glad to see that someone agrees with me. This would explain why it is (or more accurately was, I haven't heard it in the wild in a long time) a peculiarly British word – BoldBen Jul 10 at 1:41

GDoS suggest a possible origin from medieval French roussin:


(also rawser, razzer, rosser, roz)

[? Rom. roozlo, strong or roast, a villain; B&L suggest rousse, roussin, a policeman (from Medieval. Fr. roussin, a warhorse or hunter)]

a police officer; also attrib.

  • 1888 [UK] Sporting times 26 May n.p.: Up walks a rozzer and buckles me tight [B&L].

  • 1956 [UK] ‘Charles Raven’ Und. Nights 148: The Surrey rozzers pride themselves on the efficiency of their cordon system.

World Wide Words has other suggestions, none of which appears to be conclusive:

A common supposition is that it comes from Hebrew khazeer or Yiddish chazer, a pig, but this is almost certainly a guess derived from the 1960s slang term.

Yet another candidate is the Romany ruzalō, strong. Some point to roosher, contemporary with rozzer, which is listed in Farmer and Henley’s Slang and its Analogues of 1903, but that merely transfers the problem to another word of which we know nothing.

None of these have any direct evidence to support them. Once again, it’s “origin unknown”, I’m afraid.

  • The OED is unsure, but thinks that the Robert Peel connection is more likely than the Romany. – WS2 Jul 10 at 6:04
  • @WS2 - I don’t have access to the OED but I think the sources I cited (Green’s in particular) are reliable. It appears you are actually looking for a validation of what the OED says rather than possible alternatives. – user121863 Jul 10 at 9:36
  • I'm only telling you what the OED says. It is, after all, a fairly authoritative source. But the OED's conclusion is "origin unknown". – WS2 Jul 10 at 17:50
