Third person singular present of shine; emits or reflects bright light, or performs exceptionally well.
From Old English scīnan, related to German scheinen, from Proto-Germanic *skīnaną meaning 'to shine, appear bright'. The metaphorical sense of 'excelling' developed in the 16th century.
The word 'shine' has evolved from purely describing light emission to capturing human excellence - we say someone 'shines' when they perform brilliantly. Interestingly, many languages use light metaphors for intelligence and success, suggesting a universal human connection between brightness and achievement.
