European doctor managed to cut this writer's skin (8)
I believe the answer is:
membrane
'skin' is the definition.
(thesaurus)
'european doctor managed to cut this writer's' is the wordplay.
I cannot quite understand how this works, but
'european' could be 'e' (abbreviation e.g. EU) and 'e' is found within the answer.
'doctor' could be 'mb' (Bachelor of Medicine, Medicinae Baccalaureus) and 'mb' is found within the answer.
'managed' could be 'ran' (I've seen this before) and 'ran' is present in the answer.
'writer' could be 'me' (the person who is writing these clues) and 'me' is located in the answer.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for membrane that I've seen before include "Thin pliable sheet of material" , "Thin sheet covering organs" , "Thin sheet surrounding body parts" , "Thin skin-like tissue lining organs" , "Thin sheet that surrounds body parts" .)
