COP
Evan Morris's Sunday Daily News column explained "Cop." I like the
little poem in this explanation, from the Philadelphia Inquirer, Everybody's
Column, 19 February 1905, pg. 8, col. 7:
A "COP" (C. B. L.).--"Please tell me in Everybody's Column how the word
"cop" came to be applied to the policemen.
There has been a favorite rhyme among English schoolboys for generations
past which says:
"He that cops what isn't his'n,
Will be copped and put to prison."
This verb "to cop," you see, is an old-timer, meaning "to take," "to
catch," "to capture;" naturally enough a "copper" is a "catcher" (a
policeman); and (although none of our dictionaries says so) "cop" seems to us
to be nothing more than a free-and-easy popular abbreviation of "copper."
