n Hello/goodbye update: Thanks to Billie Shaffer of Clarendon, Texas, who let us know about the Navajo word “yatahey,” which can mean “hello” or “goodbye.” Don Hansen of Issaquah, Wash., told us about the Danish oddity of “hej” (pronounced “hi”) meaning “hello” and “hej-hej” meaning “goodbye.”

A recent Bit mentioned that a resident of Sydney, Australia, is called a Sydneysider. That reminded us of the word “sillysider,” which is Canadian slang for a:

A) Left-hander

B) Comedian

C) Clumsy sailor

D) Rickety building

Wednesday’s answer: The “ruth” in “ruthless” is a word meaning “pity.”
