Key Differences

Associate "Indecisive" with "indecision" – both start with "in-."
"In" typically means "not," making "Indecisive" mean "not decisive."
Think of "decision" and add "in-" for the negative form.
Remember the phrase: "It's IN to be decisive; hence, Indecisive."
There's no "un-" prefix in "decision," so it shouldn't be in its adjective form.
