Computer image of some aristocrat available to review (6)
I believe the answer is:
avatar
'computer image' is the definition.
'avatar' can be an answer for 'image' (I have seen 'Online image ' mean 'avatar' so perhaps 'image' could also mean 'avatar'). I am unsure of the 'computer' bit.
'some aristocrat available to review' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'to review' shows that the letters should be reversed in order.
'ratava' can be found hidden inside 'aristocrat available'.
'ratava' backwards is 'AVATAR'.
'of' is the link.
Can you help me to learn more?
(Other definitions for avatar that I've seen before include "Computer object representing the user" , "Divine incarnation" , "Divine manifestation" , "A person who seems to embody a particular ideal" , "Manifestation of a deity (Hinduism)" .)
