Informed where one might find toilet roll — close to mop (2,3,4)
I believe the answer is:
in the loop
'informed' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'one might find toilet roll close to mop' is the wordplay.
I cannot quite see how this works, but
'one' could be 'the' (both can introduce a definite example of something) and 'the' is present in the answer.
'toilet' could be 'loo' (loo is a kind of toilet) and 'loo' is located in the answer.
This may be the basis of clue (or it may be nonsense).
'where' acts as a link.
Can you help me to learn more?
(Other definitions for in the loop that I've seen before include "Well informed" , "briefed?" , "kept informed" .)
