Given lift when grouse endlessly seen in island group (5)
I believe the answer is:
samoa
'island group' is the definition.
(I've seen this before)
'given lift when grouse endlessly' is the wordplay.
'given lift when' becomes 'sa' (I am not sure about this - if you are sure you should believe this answer much more).
'grouse' becomes 'moan' (I've seen this in another clue).
'endlessly' means to remove the last letter.
'moan' with its final letter taken away is 'moa'.
'sa'+'moa'='SAMOA'
'seen in' is the link.
Can you help me to learn more?
(Other definitions for samoa that I've seen before include "Commonwealth country in the Pacific, capital Apia" , "Group of volcanic islands in the S Pacific" , "Pacific island nation, capital Apia" , "Group of Polynesian 14s" , "island territory" .)
