Miss, born first of December (4)
I believe the answer is:
need
'miss' is the definition.
(thesaurus)
'born first of december' is the wordplay.
'born' becomes 'nee' (I've seen this before).
'first of' suggests taking the first letters.
The first letter of 'december' is 'd'.
'nee'+'d'='NEED'
(Other definitions for need that I've seen before include "Require; want" , "Distressful situation" , "Cry out for - prerequisite" , "Necessitate" , "What's lacking" .)
