In general, apex refers to the top, the peak, or the high point of something. In typography, the point at the top of a character where two strokes meet is known as the apex The most common example is the uppercase A where the left and right strokes meet at the top. Other letters with an apex include M, N, and sometimes the the middle of a W if the strokes meeting in the middle are even with or higher than the two outer strokes.
The apex of a letter may be a sharp point, blunt, or rounded and is an identifying, sometimes quite distinctive feature for some typefaces.
