Rang the bell as instructed, we hear (6)
I believe the answer is:
tolled
'rang the bell' is the definition.
'tolled' can be an answer for 'rang' (tolling is a kind of ringing). I am unsure of the 'the bell' bit.
'instructed we hear' is the wordplay.
'instructed' becomes 'told' (I've seen this before).
'we hear' indicates a 'sounds like' (homophone) clue.
'told' is a homophone of 'TOLLED'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for tolled that I've seen before include "Of bell, rang sonorously" , "Sounded the bell" , "Rang for the dead" , "Of bell, rang solemnly" , "Rang, or charged for using" .)
