A doctor favoured hugging a man (6)
I believe the answer is:
adrian
'man' is the definition.
(I've seen this before)
'a doctor favoured hugging a' is the wordplay.
'doctor' becomes 'dr' ('Dr' can be a synonym of 'doctor'**).
'favoured' becomes 'in' (I've seen this in other clues).
'hugging' indicates putting letters inside.
'in' going around 'a' is 'ian'.
'a'+'dr'+'ian'='ADRIAN'
(Other definitions for adrian that I've seen before include "Boy" , "English pope, born Nicholas Breakspear" , "-- Mole, Sue Townsend's creation" , "The Secret Diary of ... Mole, Aged 13? (Sue Townsend)" , "Name of six Popes" .)
