The reviewer gives it credit, I see (6)
I believe the answer is:
critic
'the reviewer' is the definition.
(I've seen this before)
'it credit i see' is the wordplay.
I cannot really understand how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is found in the answer.
'credit' could be 'cr' (abbreviation) and 'cr' is located in the answer.
'i' is within the answer.
'see' could be 'c' (the word for the letter, according to Chambers) and 'c' is located in the answer.
A single letter 'i' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'gives' acts as a link.
Can you help me to learn more?
(Other definitions for critic that I've seen before include "One writing reviews" , "One judges the merit of artistic works" , "Reviewer of plays, films etc" , "(Eg, theatre) reviewer" , "Newspaper reviewer" .)
