Boatman adrift around island somewhere across the pond (8)
I believe the answer is:
manitoba
'somewhere across the pond' is the definition.
I can't tell whether this defines the answer.
'boatman adrift around island' is the wordplay.
'adrift' is an anagram indicator.
'around' means one lot of letters goes inside another.
'island' becomes 'i'.
'boatman' is an anagram of 'mantoba'.
'mantoba' placed around 'i' is 'MANITOBA'.
Can you help me to learn more?
(Other definitions for manitoba that I've seen before include "Strange boatman I find in Canada" , "Is Oman a bit in Canada, strangely?" , "part of N America" , "Winnipeg area" , "region bordering Hudson Bay" .)
