Refer to work Greek character turned up that's prosaic (8)
I believe the answer is:
unpoetic
'prosaic' is the definition.
(I've seen this before)
'refer to work greek character turned up' is the wordplay.
'refer to' becomes 'cite' (synonyms).
'work' becomes 'op' (common abbreviation for 'opus').
'greek character' becomes 'nu' (letter from the Greek alphabet).
'turned up' shows that the letters should be reversed in order.
'cite'+'op'+'nu'='citeopnu'
'citeopnu' written backwards gives 'UNPOETIC'.
'that's' is the link.
(Other definitions for unpoetic that I've seen before include "Not in the style of verse" , "prosaic" .)
