Unscripted → It is formed from "un-" (meaning not) and "scripted" (from Latin "scriptus", meaning written). The word "unscripted" means not written or not prepared in advance, often referring to spontaneous or improvised speech or action.
Think of 'not' ('un-') being combined with 'written' ('scriptus') to remember that 'unscripted' refers to something that is not pre-written or planned.
