She is supercautious about crossing the street, always looking both ways before stepping off the curb.
Supercautious → It is formed from "super-" (meaning above or beyond) and "cautious" (from Latin "cautiosus", meaning careful or wary). The word "supercautious" means being excessively careful or wary beyond the usual level.
Think of being 'above' ('super-') the usual level of 'carefulness' ('cautious') — that's why supercautious means being extremely careful.
