Girl speaks about love where keepers sought? (10)

'keepers sought?' is the definition.
I can't tell whether this definition defines the answer.

'girl speaks about love' is the wordplay.
I cannot quite understand how this works, but
'girl' could be 'g' and 'g' is found within the answer.
'speaks' could be 'mouths' ('mouth' can be a synonym of 'speak') and 'mouths' is found within the answer.
'about' could be 'a' (abbreviation in Chambers) and 'a' is located in the answer.
'love' could be 'o' (love means zero in tennis) and 'o' is found within the answer.
A single letter 'l' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

'where' is the link.

Can you help me to learn more?
