Hymn

A hymn (the '-n' is silent: 'hymn' sounds like 'him') is a song in praise of God. It is usually intended to be sung in church, as part of a religious service: but hymns can besung anywhere.

The verb 'to hymn' means 'to sing the praises of', 'to sing hymns to' God. There is a figurative use in addition, where admirers of asomewone can be said to 'hymn her (or his) praises'.
