pion (English)
Where does "pion" come from?
The English noun 'pion' is formed by combining the letter name 'pi' with the suffix '-on'[1], creating an alteration of the earlier term 'pi-meson'[1]. The root 'pi' itself comes from the Ancient Greek letter name 'πεῖ'[2], which was borrowed from the Phoenician letter name meaning 'mouth'[3].
