Refuse to be enclosed in this cruise ship? (5)
I believe the answer is:
liner
'this cruise ship?' is the definition.
(I've seen this in another clue)
'refuse to be enclosed in' is the wordplay.
I cannot really see how this works, but
'in' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for liner that I've seen before include "eg QE2" , "Cosmetic; fine paintbrush" , "Large passenger-ship" , "It covers bin's interior" , "may be demonstrated by make-up artist" .)
