be jealous of, be envious
媢 centers on a resentful, envious feeling, especially in a personal or emotional context. The given meanings of jealousy and envy are direct expressions of this core idea.
媢 combines 女 (woman) with 冒, which likely contributes the sound and may relate to covering or offending, suggesting a hidden or offensive feeling. The exact historical development is uncertain.
A woman 女 beside 冒, which looks like a covered eye, suggests a jealous glare hidden behind a mask. Picture someone peeking out with envy.
For ボウ, imagine a jealous person throwing a bow (as in bow and arrow) at the object of their envy: bow -> ボウ, and the arrow is aimed with resentment.
