anti-
反 centers on opposition and reversal: being against something, turning back, or bending away from a straight path. The single gloss 'anti-' captures the core idea of facing or moving in the opposite direction.
反 is traditionally explained as a hand 又 bending or turning something, with 厂 possibly representing a bent object or a cliff face. The idea of bending back or opposing is central.
The right side 又 is a hand, and the left side 厂 looks like a bent surface. Picture a hand pressing against a bent wall, pushing back in opposition: 反 means anti- or reverse.
For ハン, imagine a hand pushing back against a huge pan: pan -> ハン, and the hand is opposing the pan's weight.
