🤝 tomoni sounds like Tommy-and-me: doing it together
The kanji 共 means together, the same one in 共通 (kyōtsū, shared in common). Add に and you get 共に: together with, sharing in. Tommy and me, side by side, ties the sound to the meaning.
共 — 两手 (廾) holding up an object
共 originally depicted two hands raised together, lifting or offering something jointly. The ancient form showed a vessel or object held up by paired hands, conveying shared action. From 'lifting together' it shifted to mean 'together,' 'common,' or 'share.'
