All around bar beside a new bar by port in region of Canada (8)
I believe the answer is:
labrador
'region of canada' is the definition.
(I've seen this in another clue)
'all around bar beside a new bar by' is the wordplay.
'around' says to take the centre.
'bar' becomes 'dor' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'beside' means one lot of letters go next to another.
'new' is an anagram indicator.
'by' means one lot of letters go next to another.
The middle letter of 'all' is 'l'.
'bar' anagrammed gives 'bra'.
'a' put next to 'bra' is 'abra'.
'dor' put after 'abra' is 'abrador'.
'l'+'abrador'='LABRADOR'
'port in' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for labrador that I've seen before include "Coastal region of eastern Canada" , "Type of retriever" , "Breed of gun dog" , "One that may have gone out with the guns" , "Newfoundland area; dog" .)
