感叹

to sigh
😮💨 感 = feel + 叹 = sigh; literally 'feel-sigh' — a heartfelt sigh
感 (feel/emotion) + 叹 (sigh/exclaim). The compound names the act of sighing because something moves you — admiration, regret, or awe. 叹 itself contains 口 (mouth), the source of the audible sigh.
感 — heart 心 + 咸 (xián, phonetic)
A semantic-phonetic compound. The heart radical 心 at the bottom carries the meaning of feeling or emotion, while 咸 supplies the sound. Together 感 conveys being moved in the heart, hence 'to feel,' 'sense,' or 'be affected by' something.
