What does 'osculate' mean?

Osculate (verb): To kiss. In mathematics, it describes when two curves share the same tangent and curvature at a single point.

From the Latin osculum (meaning "little mouth"), osculate is a rare yet delightfully versatile word. While it’s commonly used in geometry, it’s also a fancy way to describe locking lips. Today, we explore how a math term became synonymous with romance and why you should sneak this word into your vocabulary.
