Article about one doctor with left finger protector (7)
I believe the answer is:
thimble
'finger protector' is the definition.
(I've seen this before)
'article about one doctor with left' is the wordplay.
I cannot really understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is located in the answer.
'doctor' could be 'mb' (Bachelor of Medicine) and 'mb' is located in the answer.
'left' could be 'l' (common abbreviation) and 'l' is located in the answer.
'article' could be 'the' (the definite article in English) and 'the' is found in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for thimble that I've seen before include "Belt him, carrying finger protector" , "Digital protection" , "Sewer's protection" , "Caucus-race prize (Alice)" , "Protection for part of arm" .)
