Nominally backward, a bit introverted (6)
I believe the answer is:
trevor
'nominally backward a bit introverted' is the definition.
I can't tell whether this defines the answer.
'backward a bit introverted' is the wordplay.
'backward' shows that the letters should be reversed in order.
'a bit' indicates the answer is hidden within the clue (the answer is formed by a bit of the clue).
'rovert' is hidden within 'introverted'.
'rovert' reversed gives 'TREVOR'.
Can you help me to learn more?
(Other definitions for trevor that I've seen before include "Man's name" , "- Howard, English actor (Mutiny on the Bounty)" , "Chap" , "boy" , "Fellow" .)
