Going round Greek island one sees a lively dance (9)
I believe the answer is:
ecossaise
'dance' is the definition.
(I've seen this before)
'going round greek island one sees a lively' is the wordplay.
I cannot quite see how this works, but
'round' could be 'o' (round can mean a round object) and 'o' is located in the answer.
'island' could be 'is' (abbreviation) and 'is' is located in the answer.
'one' could be 'a' (a thing is one thing) and 'a' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for ecossaise that I've seen is " Country dance".)
