infectious
🦠 感 feel + 染 dye/infect + 力 power = power to infect others with feeling
感 (feel) + 染 (to dye, to infect) + 力 (power/force). Literally the force that dyes or infects others with your feeling — used for charisma, contagious enthusiasm, or inspirational pull.
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.
染 — water 氵 + nine 九 + wood 木
染 depicts the dyeing process: 氵 (water) for the dye liquid, 木 (wood) for plant-based dyestuffs, and 九 (nine) suggesting repeated dippings to deepen the color. Originally meaning 'to dye cloth,' it later extended to figurative senses like 'to be influenced' or 'to contract' (as in illness).
力 — pictograph of a plow or arm muscle
力 originated as a pictograph of an ancient plow, the main tool requiring physical exertion in early agriculture. Some scholars also see it as a flexed arm showing muscle. From this concrete image it broadened to mean 'strength, power, force, effort'.
