What's the  word I'm thinking of? Today, it's... 

ZEPHYR  (noun)

A gentle, refreshing wind; also the Greek god of the west wind.

"He saw attempted murder in the pains of green-apple colic, cyclones in the summer zephyr, lost children in every top-spinning urchin, an uprising of the down-trodden masses in every hurling of a derelict potato at a passing automobile."
--O. Henry, "Whirligigs" (1923)
