orthogonal

PRONUNCIATION:
(or-THOG-uh-nuhl)

MEANING:
adjective:
   1. At right angles.
   2. Unrelated or independent of each other.

ETYMOLOGY:
From Latin orthogonius (right-angled), from Greek orthogonios, from ortho- (right, correct) + gonia (angle). Ultimately from the Indo-European root genu- (knee), which also gave us knee, kneel, genuflect, and diagonal. Earliest documented use: before 1560.

USAGE:
"I've always liked the idea of belonging to a union, but then again they always seemed orthogonal to what I was actually doing with my life."
Now That's A Really Good Question; The Economist (London, UK); Feb 22, 2011.

A THOUGHT FOR TODAY:
Our chief want in life is somebody who shall make us do what we can. -Ralph Waldo Emerson, writer and philosopher (1803-1882)
