I've seen "arm" but in other letters that refers to more perpendicular parts (e.g. /E, /F).
I've seen "shoulder" but in other letters that refers to a hump that continues down to the baseline (e.g. /n, /h)
I've seen "ear" which otherwise I think only is used with a binocular /g, but Van Gogh was still recognizable after he cut off his ear.
What do you
