decide, fix, agree upon, appoint
決 centers on making a firm choice or settlement: deciding, fixing, agreeing upon, or appointing something with finality.
決 combines 氵 (water) with 夬, which likely contributes the sound and the idea of separating or breaking through, suggesting water cutting a channel and thus a decisive action.
Water 氵 flows and cuts a clear path through the right side 夬, like a decision cutting through uncertainty.
For ケツ, imagine a decisive person named Ketsu who always makes quick decisions: Ketsu -> ケツ, and their firm choice is like water cutting a channel.
