Lee is odd name for girl (5)
I believe the answer is:
elsie
'name for girl' is the definition.
(I've seen this before)
'lee is odd' is the wordplay.
'odd' indicates an anagram.
'lee'+'is'='leeis'
'leeis' is an anagram of '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" .)
