痛 — sickness radical 疒 + 甬 (yǒng, phonetic)
痛 is a semantic-phonetic compound. The 疒 radical depicts a person on a sickbed and signals illness or pain. The component 甬 supplies the sound, historically close to 'tòng'. Together they convey bodily ache, later extended to emotional pain and the adverbial sense 'thoroughly'.
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.
