Etymology: Ancient Greek had a word for a beard, "pōgōn", and from it came the diminutive "pōgōnion", meaning a little beard. The chin is the spot where a beard grows, so the name shifted from the hair to the place it covered. In Modern Greek, the everyday word for chin is "pigoúni", which descends from the same root and shows how the beard-word attached itself to the chin. English took the term as a technical anatomical name, so it is a learned borrowing rather than an ordinary everyday word. Its use is confined to anatomy, orthodontics, and facial measurement, where it marks the most forward point of the chin in profile. The word therefore preserves an old link between chin and beard that the ordinary English word "chin" has lost.
