Scotsman's ecstasy coming into Hebridean isle's elongated bay (6,3)
I believe the answer is:
ionian sea
'elongated bay' is the definition.
The definition suggests a singular noun which matches the answer.
'scotsman's ecstasy coming into hebridean isle's' is the wordplay.
'scotsman's' becomes 'ian's' (common Scottish name).
'ecstasy' becomes 'E' (informal term for the drug).
'coming into' is an insertion indicator.
'hebridean isle' becomes 'iona' (I've seen this before).
'ians'+'e'='ianse'
'ianse' placed within 'iona' is 'IONIAN SEA'.
Can you help me to learn more?
(Other definitions for ionian sea that I've seen before include "Part of the Mediterranean" , "Greek waters" , "Mediterranean area" , "Corfu location" , "Waters surrounding Corfu and Paxos" .)
