About this kanji
The kanji 硬 represents the idea of hardness or being solid. It is often used as an adjective, with the kun'yomi reading かた.い (katai) meaning "hard". You’ll find it in useful compounds like 硬貨 (こうか, kouka), which means "coin," referring to hard currency, and 硬度 (こうど, koudou), meaning "hardness," which measures how hard something is. Another important compound is 硬化 (こうか, kouka), which means "hardening," a process where something becomes firm. A usage note is that while it describes physical hardness, it can also refer to figurative hardness, like a stubborn attitude.
