Roaming brother is due to tour European islands (5,8)
I believe the answer is:
outer hebrides
'roaming brother is due to tour european islands' is the definition.
I can't tell whether this defines the answer.
'roaming brother is due to tour european' is the wordplay.
'roaming' indicates anagramming the letters.
'to tour' indicates putting letters inside (to tour can mean to go around).
'european' becomes 'E' (abbreviation e.g. EU).
'brother'+'is'+'due'='brotherisdue'
'brotherisdue' with letters rearranged gives 'outerhebrids'.
'outerhebrids' enclosing 'e' is 'OUTER HEBRIDES'.
Can you help me to learn more?
(Other definitions for outer hebrides that I've seen before include "remote Scottish area" , "Lewis and Harris location" , "Island group containing Lewis and Harris" , "The Western Isles" , "Scots isles" .)
