Unadvised → It is formed from "un-" (meaning not) and "advised" (from Latin "advisare", meaning to consider or deliberate). The word "unadvised" means not having considered or deliberated, often implying a lack of caution or thoughtfulness in decision-making.
Think of 'not' ('un-') having 'considered' something ('advisare') — that's why unadvised means not having thought things through.
