Abstract noun referring to the quality of being superior or excellent. Often used in formal or literary contexts.

Archaic adjectival noun meaning skillful or adept. Rarely used in modern Japanese outside of classical texts.

In classical texts, '優なる者' meant 'a skillful person'.
良 is one grade lower than 優 on the same 優・良・可 academic grading scale.
可 is the lowest passing grade, well below 優 on the same grading scale.
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.
