Origin

This character combines a hand radical on the left with the character 最 (sai) on the right, which serves as a sound hint for the pronunciation. The hand component 扌 indicates the character involves a manual action—something you do with your hands. When you take a picture or snapshot, you use your hands to operate a camera, so the hand radical captures that physical act of grasping or manipulating something. The 最 component tells you roughly how to pronounce the word (sai becomes sats in the reading), while the hand element carries the meaning of a hands-on action.
