"Ah, gotcha"

ISEE

What you might say when suddenly understanding something in just two short words.

The clue "Ah, gotcha" mimics the sound of someone suddenly understanding something, like saying "Ah, I see!" out loud. The answer "ISEE" captures that phrase shortened into a casual, almost text-speak version. It’s a straightforward pun where the spoken reaction becomes the written solution, playing on how we abbreviate common expressions.
