Plural of excellence; multiple instances or types of outstanding quality, virtue, or superiority.
From 'excellence' (from Latin 'excellentia') + '-es' (plural). Excellence means the quality of being excellent, and its plural captures multiple expressions or forms of this quality.
The plural 'excellences' is interesting because excellence seems like it should be uncountable (you can't have 'two excellences'), but you absolutely can—each skill or virtue can show its own excellence.
