Could you do a bit worse than open them? (5)
I believe the answer is:
doors
'a bit worse than open them?' is the definition.
I can't tell whether this defines the answer.
'could you do' is the wordplay.
I cannot really understand how this works, but
'do' is within the answer.
The remaining letters 'ors' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for doors that I've seen before include "Openings" , "Barriers to entrances" , "Ways in and out" , "Portals" , "Swinging or sliding barriers" .)
