애정하다 ae-jeong-ha-da
Modern, casual verb for "to really love or be fond of" something
A younger-generation twist — turning the noun '애정' (affection) into a casual verb, the way English speakers might say 'I'm really into this'. You'll hear '나 이 노래 애정해' from someone in their 20s far more than from their parents.
