Informed where toilet paper is soft (2,3,4)
I believe the answer is:
in the loop
'soft' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'informed where toilet paper' is the wordplay.
I cannot quite see how this works, but
'toilet' could be 'loo' (loo is a kind of toilet) and 'loo' is present in the answer.
'informed' could be 'hep' ('hep' can be similar in meaning to 'informed') and 'hep' is located in the leftover letters.
'paper' could be 'i' (UK newspaper) and 'i' is present in the answer.
This may be the basis of clue (or it may be nonsense).
'is' acts as a link.
Can you help me to learn more?
(Other definitions for in the loop that I've seen before include "briefed?" , "Well informed" , "kept informed" .)
