Cautiously → It is formed from "cautious" (from Latin "cautiosus", meaning careful or wary) and the suffix "-ly" (meaning in a manner of). The word "cautiously" means in a careful or wary manner.
Think of being 'careful' ('cautious') and doing something 'in a manner of' ('-ly'). This helps you remember that cautiously means acting in a careful way.
