Vertex (typography)
In typography, a vertex is a sharp point made where two strokes meet at the bottom of the strokes, as in the letters "V" and "W". The counter area above the two strokes also typically has a sharp corner,
called a crotch; this can also exist even in letters like "Y" that have no vertex.
The opposite of a vertex, the point where two strokes meet at the top of the strokes, is called an apex.
