Sherlock Holmes speaks of a "crony" of the landlady. I
wondered about the etymology. From AHD:
crony

SYLLABICATION: cro·ny
PRONUNCIATION: krn
NOUN: Inflected forms: pl. cro·nies
A longtime close friend or companion.
ETYMOLOGY: Possibly from Greek khronios, long lasting, from khronos, time.

Oh, I do love learning here, wwh, that crony came from khronos for time. To think of those friends with whom we've shared long, long streches of time is simply rich.

I wish we called them khronies instead--I can just about hear that great movement of time in one of the movements from Holst's "The Planets."
