a quick question. What is the correct term of this (see picture) on a font?
- joint: gradual coming together of two strokes that meet to become one.
Could also be called the apophyge in some situations:
- apophyge: small curved part, usually ¼ circle, which connects the main stem with the terminals or serifs.
Also realize you've kind of circled the joint of a tail, a crossbar, and an bowl/stem.
In the case of p or t, it seems apophyge may be more appropriate. But the tail would be a joint.
