Variety of green fruit sent by English company (6)
I believe the answer is:
econut
'variety of green' is the definition.
'econut' can be an answer for 'green' (I've seen this before). I'm not sure about the 'variety of' bit.
'fruit sent by english company' is the wordplay.
I cannot really understand how this works, but
'fruit' could be 'nut' (nut is a kind of fruit) and 'nut' is present in the answer.
'english' could be 'e' (abbreviation) and 'e' is found in the answer.
'company' could be 'co' (abbreviation) and 'co' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for econut that I've seen is " green activist".)
