IPA: /ˈhɑːrdiər/
KK: /ˈhɑrdiər/
More able to withstand difficult conditions or challenges than others.
This plant is hardier than the others, surviving even in harsh weather.
Hardier → It is formed from "hard" (from Old English "heard", meaning solid or firm) and "-ier" (a comparative suffix indicating more). The word "hardier" means more solid or firm than something else, indicating greater strength or resilience.
Think of something that is 'more solid' or 'more firm' — 'hard' means solid, and '-ier' shows a comparison, so hardier means stronger or tougher.
