Current authority protecting large part of Scotland (5)
I believe the answer is:
islay
'scotland' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'current authority protecting large part' is the wordplay.
'current' becomes 'I' (symbol for electric current).
'authority' becomes 'say' (I've seen this in another clue).
'protecting' means one lot of letters goes inside another (inserted letters are held or protected).
'part' says to take the initial letters.
The first letter of 'large' is 'l'.
'say' going around 'l' is 'slay'.
'i'+'slay'='ISLAY'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for islay that I've seen before include "malt from here!" , "somewhere off Scottish mainland" , "Scottish island" , "Isle known for distilleries" , "Island of the Inner Hebrides" .)
