🙏 扌(hand) + 共 (together) = hands brought together in salute
The hand radical 扌plus 共 (gòng, together) gives 拱 — two hands joined together, the classic cupped-hand bow. 共 also lends the sound (gòng → gǒng). From that core sense it extends to surrounding, arching over, or a pig rooting earth with its snout.
拱 — hand radical 扌 + 共 gòng (phonetic)
A semantic-phonetic compound. The hand radical 扌 gives the meaning, showing an action done with the hands, while 共 supplies the sound (gòng → gǒng). The original sense is to cup the hands together in a respectful salute, later extended to 'arch' or 'vault' shapes formed by joined hands.
