tangency
Meeting at one
Tangency is the state of touching at a single point without crossing.
In geometry, a line has tangency with a circle when it meets the curve at exactly one point.
The word extends to any situation of minimal contact or brief intersection: the tangency between their lives lasted only a summer.
