Red Sea to French crowd (6)
I believe the answer is:
merlot
'red' is the definition.
(I know that Merlot is a red)
'sea to french crowd' is the wordplay.
'sea' becomes 'mer' (I have seen 'French sea ' mean 'mer' so perhaps 'sea' could also mean 'mer').
'to' means one lot of letters go next to another.
'french crowd' becomes 'lot' (a lot of people. I am not sure about the 'french' bit.).
'mer'+'lot'='MERLOT'
Can you help me to learn more?
(Other definitions for merlot that I've seen before include "Wine-producing black grape" , "Wine made from bad elm rot" , "Strange wine made from elm rot" , "Red wine grape variety" , "Kind of wine grape" .)
