Suitable cut-out for computer (6)
I believe the answer is:
laptop
'computer' is the definition.
(laptop computer is a kind of computer)
'suitable cut-out' is the wordplay.
'suitable' becomes 'apt' (I've seen this before).
'cut' becomes 'lop' (lopping is a kind of cutting**).
'out' is an insertion indicator.
'apt' inserted within 'lop' is 'LAPTOP'.
'for' acts as a link.
(Other definitions for laptop that I've seen before include "Some work on this" , "Kind of computer" , "Type of computer" , "device?" , "PC" .)
