Etymology

Origin of indecisive

First recorded in 1720–30; in- 3 + decisive

Explanation

If you’re indecisive, you have a hard time making decisions. When you finally do make a decision, you may not be confident about it, or you might change your mind. Another definition for indecisive is not definitely settling something, like when election results are too close to call or some result has been called into question. Several historic American elections have had this happen in the recent past, and in that case, the election result remains indecisive until a recount has been finished or until one party gives a concession speech.
