Wine produced by Middle Eastern country endlessly (7)
I believe the answer is:
madeira
'wine' is the definition.
(Madeira is an example)
'produced by middle eastern country endlessly' is the wordplay.
'produced' becomes 'made' ('make' can be a synonym of 'produce'**).
'by' means one lot of letters go next to another.
'middle eastern country' becomes 'iraq' (I've seen this before).
'endlessly' means to remove the last letter.
'iraq' with its last letter removed is 'ira'.
'made'+'ira'='MADEIRA'
(Other definitions for madeira that I've seen before include "drink" , "Portuguese North Atlantic island" , "Dessert wine from a Portuguese Atlantic island" , "Sponge-cake" , "Portuguese island, capital Funchal" .)
