Girl clipping the edges off marigold sloppily (6)

I believe the answer is:

gloria

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

'girl' is the definition.

I don't understand how the rest of the clue works.

(Other definitions for gloria that I've seen before include "Prayer: '... in excelsis Deo'" , "Woman's name - Christian hymn praising God" , "piece of church music" , "Doxology" , "Part of the Mass; name" .)

I've seen this clue in The Times.
