Fears medic will encounter cases of extra drunkenness (6)
I believe the answer is:
dreads
'fears' is the definition.
('dread' can be a synonym of 'fear')
'medic will encounter cases of extra drunkenness' is the wordplay.
I cannot quite understand how this works, but
'medic' could be 'dr' and 'dr' is found in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for dreads that I've seen before include "Worries about" , "Looks ahead with apprehension" , "Greatly fears, is most apprehensive of" , "Is in great fear of" , "Is terrified" .)
