Cough mixture was our connection, we hear (7)
I believe the answer is:
linctus
'cough mixture' is the definition.
(I've seen this before)
'our connection we hear' is the wordplay.
I cannot quite understand how this works, but
'we' could be 'us' and 'us' is found in the answer.
This explanation may well be incorrect...
'was' is the link.
Can you help me to learn more?
(Other definitions for linctus that I've seen before include "Thick cough mixture" , "The prescription" , "Syrup that may see a cough off" , "Syrupy medicine to relieve sore throats" , "Thick liquid medicine" .)
