Is suet made out of paper? (6)
I believe the answer is:
tissue
'paper?' is the definition.
(I know that tissue is a type of paper)
'is suet made out of' is the wordplay.
'made' indicates anagramming the letters.
'out of' means one lot of letters goes inside another (some letters on the outside of others).
'suet' anagrammed gives 'tsue'.
'is' placed within 'tsue' is 'TISSUE'.
(Other definitions for tissue that I've seen before include "load of lies?" , "Thin stuff" , "cell block?" , "Disposable piece of absorbent paper" , "light material" .)
