What semantic field underlies 即?

Question

I can grasp how卩 (“to kneel”) relates to definitions 1-3 below. But how does 皀 + 卩 compound to mean definitions 4-14 that don't relate to food or kneeling and that all differ from each other? Definitions 5 and 7 are the ones that overlap at all! I screenshot Yellowbridge.

Answer 2

甲金文从「皀」从「卩」，像人跪（卩）于食器前就食之形，本义是就食，引申为接近。
