Doctor should admit tense Scottish leader (8)
I believe the answer is:
sturgeon
'scottish leader' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'doctor should admit tense' is the wordplay.
'doctor' becomes 'surgeon' (surgeon is a kind of doctor).
'should admit' indicates putting letters inside.
'tense' becomes 't' (grammatical abbreviation).
'surgeon' enclosing 't' is 'STURGEON'.
Can you help me to learn more?
(Other definitions for sturgeon that I've seen before include "The fish for caviars" , "Fish sought for caviar" , "Egg producer" , "provider of delicacy?" , "Main resident" .)
