Girl seen around May (3)
I believe the answer is:
amy
'girl' is the definition.
'around may' is the wordplay.
'around' is an anagram indicator.
'may' is an anagram of 'AMY'.
'seen' is the link.
(Other definitions for amy that I've seen before include "Girl" , "- Johnson, Eng. aviatrix" , "Youngest of Little Women" , "--, Johnson, solo flyer" , "so-called little woman" .)
