A severe medic in English street closest to where the sun rises (11)
I believe the answer is:
easternmost
'closest to where the sun rises' is the definition.
(the sun rises in the east)
'a severe medic in english street' is the wordplay.
'a severe' becomes 'stern' (I've seen this in another clue).
'medic' becomes 'mo' (medical officer).
'in' indicates putting letters inside.
'english street' becomes 'east' (I can't explain this - if you can you should believe this answer much more).
'stern'+'mo'='sternmo'
'sternmo' placed inside 'east' is 'EASTERNMOST'.
Can you help me to learn more?
(Other definitions for easternmost that I've seen before include "closest to where the sun rises" , "extreme geographical location" , "on the extreme right, conventionally" , "Furthest from the west" .)
