From the Latin osculum, meaning kiss.

Osculate is used in science and geometry to describe where two surfaces contact to create new tangents.

Yes, 'osculate' has two meanings, as mentioned by drpalidin.

Fortunately for us there are multiple, at least one more:

Osculate was created in the 17th Century, but its first use came in the 19th Century.

A case of frustratingly, delayed osculation?

Probably good that middle school math only deals in intersections. Teachers could never get through it.

The Latin root is osculum, the diminutive of mouth. Os is mouth. If you see "P.O." on your prescription bottle, it stands for per os "take by mouth." If your surgery order says NPO after midnight, it is for nil per os -- nothing by mouth, i.e. don't eat anything.

Osccul I m can mean mouth, but kiss is the primary usage.
