Medicine initially under suspicion after lawyer's debut in court (7)
I believe the answer is:
linctus
'medicine' is the definition.
(I've seen this before)
'initially under suspicion after lawyer's debut in court' is the wordplay.
'initially' says to take the initial letters.
'after' says to put letters next to each other.
'debut' says to take the initial letters.
'court' becomes 'ct' (abbreviation used in road names).
The first letters of 'under suspicion' is 'us'.
The initial letter of 'lawyers' is 'l'.
'l'+'in'+'ct'='linct'
'us' put after 'linct' is 'LINCTUS'.
(Other definitions for linctus that I've seen before include "Syrup that may see a cough off" , "Syrupy medicine to relieve sore throats" , "Cough medicine" , "The prescription" , "Thick liquid medicine" .)
