Sailor married to girl in sci-fi film (6)
I believe the answer is:
avatar
'sci-fi film' is the definition.
'avatar' can be an answer for 'film' (I've seen this before). I am not certain of the 'sci-fi' bit.
'sailor married to girl' is the wordplay.
'sailor' becomes 'tar' (slang term for a sailor).
'married to' says to put letters next to each other.
'girl' becomes 'ava' ().
'tar' after 'ava' is 'AVATAR'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for avatar that I've seen before include "Cyberspace representation of a person" , "Hindu manifestation of deity in human form" , "Computer object representing the user" , "Incarnation; film (2009)" , "Human or animal manifestation of Vishnu" .)
