dotted

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

Here is my best explanation:

'line' is the definition.
(thesaurus)

'girl and boy forming a sort' is the wordplay.
I cannot quite see how this works, but
'girl' could be 'ted' and 'ted' is located in the answer.
The remaining letters 'dot' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

'of' is the link.
