I'm a little stuck... Click here to teach me more about this clue!

'religious song' is the definition.
(hymn is a kind of religious song)

I can't explain the rest of the clue.

(Other definitions for hymn that I've seen before include "Godly song" , "Song of praise to God" , "Song sung in church" , "religious works" , "Psalm" .)

I've seen this clue in the Sydney Morning Herald.
