Right in but it's taken out (7)
I believe the answer is:
excerpt
'taken out' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'right in but' is the wordplay.
'right' becomes 'r' (abbreviation).
'in' means one lot of letters goes inside another.
'but' becomes 'except' (I've seen this in another clue).
'r' put into 'except' is 'EXCERPT'.
'it's' is the link.
Can you help me to learn more?
(Other definitions for excerpt that I've seen before include "Selection, extract" , "Selected passage from larger work" , "Short passage" , "Sample of work" , "bit of work" .)
