Bow before cool wind getting up round islands (11)
I believe the answer is:
archipelago
'islands' is the definition.
(I've seen this before)
'bow before cool wind getting up round' is the wordplay.
'bow' becomes 'arc' (synonyms).
'before cool' becomes 'hip' (I am not sure about the 'before' bit.).
'wind' becomes 'gale' (gale is a kind of wind).
'getting up' says the letters should be written in reverse.
'round' becomes 'o' (round can mean a round object).
'gale' back-to-front is 'elag'.
'arc'+'hip'+'elag'+'o'='ARCHIPELAGO'
Can you help me to learn more?
(Other definitions for archipelago that I've seen before include "Bahrain, for one" , "Extensive group of islands" , "Group of many islands" , "the Philippines maybe" , "Large group of islands" .)
