態

Phono-semantic compound:

心 (heart, mind) – semantic, indicating emotion, inner state

能 (ability, to be able) – phonetic element, here reflecting an older reading (nai), which later shifted to tai

The character conveys the outward expression of inner feelings, hence "appearance," "state," or "attitude."

形態 (형태) – form, shape, morphology

態度 (태도) – attitude, manner, bearing

常態 (상태) – normal state, usual condition

實態 (실태) – actual condition, reality

生態 (생태) – ecology, mode of life

The phonetic element 能 is not related in meaning to “態,” but its archaic pronunciation provided the sound base.

Closely paired with 形 (form) to form 形態, highlighting both external shape and internal state.
