Find loo or skip preliminaries and take a little stroll behind walls? (7)
I believe the answer is:
indoors
'a little stroll behind walls?' is the definition.
I can't judge whether this definition defines the answer.
'find loo or skip preliminaries and take' is the wordplay.
I cannot really see how this works, but
'or' is within the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is found within the answer.
'take' could be 'do' ('To take' a course is 'to do' a course) and 'do' is present in the answer.
The remaining letters 'is' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for indoors that I've seen before include "With a roof over one's head?" , "Inside a building" , "Within the four walls" , "under cover" , "Covered" .)
