Linguistic Note on Compass

A compass should strictly be called a pair of compasses (using the same idea as a pair of scissors), but this is considered pedantic.

Note, however, that compass is also the word for a navigational aid based upon the north-pointing property of a magnetized needle.

If there exists any risk of confusion, then pair of compasses is preferred.
