Etymology

"Undecided" combines the negative prefix "un-" with "decided," which stems from the Latin "decidere" (to cut off). The word evolved through Old French "decider" before entering English, retaining the sense of resolving uncertainty. The addition of "un-" flips the meaning to "not resolved," reflecting hesitation or lack of conclusion.
