Toilet paper's beginning to twist (4)
I believe the answer is:
loop
'twist' is the definition.
(thesaurus)
'toilet paper's beginning' is the wordplay.
'toilet' becomes 'loo' (loo is a kind of toilet).
'beginning' says to take the initial letters.
The first letter of 'papers' is 'p'.
'loo'+'p'='LOOP'
'to' acts as a link.
(Other definitions for loop that I've seen before include "Oval or U-shaped coil or bend" , "Closed circuit eg as hearing aid" , "Aircraft manoeuvre; encircle" , "Noose" , "Branch line" .)
