優しい is the common modern word for 'kind' or 'gentle', while 優 used to mean 'gentle' is literary and rarely used today.
有 and 優 are pronounced identically as ゆう but 有 means 'existence/possession' while 優 means 'excellent/superior,' so context and kanji are needed to distinguish them.
The kanji 優 originally depicts a person with a sorrowful expression, later extended to mean 'gentle', 'superior', or 'actor'. The reading ゆう is the on'yomi. The grading sense is a modern usage derived from the idea of excellence.
