Lee is odd name for girl (5)
I believe the answer is:
'name for girl' is the definition.
(I've seen this before)
'lee is odd' is the wordplay.
'odd' indicates anagramming the letters.
'leeis' with letters rearranged gives 'ELSIE'.
(Other definitions for elsie that I've seen before include "Girl's name" , "Female name; rhymes with London football team" , "Name for girl" , "Lady" , "woman" .)
