Embargo on articles - fruit? (6)
I believe the answer is:
banana
'fruit?' is the definition.
(type of fruit)
'embargo on articles' is the wordplay.
'embargo' becomes 'ban' (a ban on trade).
'on' is a charade indicator (letters next to each other) (in a down clue, letters appear on others).
'articles' becomes 'ana' ('an' and 'a', English indefinite articles).
'ban'+'ana'='BANANA'
(Other definitions for banana that I've seen before include "Fruit led by prohibition" , "Plantain-like fruit" , "Fruit that comes in a bunch" , "Curved fruit (in a split dessert?)" , "Fruit with soft, sweet flesh" .)
