Fog and rain at the front enveloping European man (6)
I believe the answer is:
mister
'front enveloping european man' is the definition.
'mister' can be an answer for 'man' (mister is a kind of man). I am not sure about the 'front enveloping european' bit.
'fog and rain at' is the wordplay.
'fog' becomes 'mist' (synonyms).
'and' is a charade indicator (letters next to each other).
'rain at' becomes 'er' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'mist'+'er'='MISTER'
'the' acts as a link.
Can you help me to learn more?
(Other definitions for mister that I've seen before include "Mr" , "Bloke" , "that's what you'd call him" , "Form of address to a man, used without his name" , "Merits of form of address to man" .)
