Warmer in the main with huge opening flower? (4,6)
I believe the answer is:
gulf stream
'warmer in the main with huge opening flower?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'opening flower?' is the wordplay.
'opening' becomes 'gulf' (gulf is a kind of opening).
'flower?' becomes 'stream' (I've seen this before).
'gulf'+'stream'='GULF STREAM'
Can you help me to learn more?
(Other definitions for gulf stream that I've seen before include "Warm Atlantic current" , "thats currently warming us" , "North Atlantic Drift" .)
