Good press extremely desirable for wine department (7)
I believe the answer is:
gironde
'wine department' is the definition.
'gironde' can be an answer for 'department' (I have seen 'French department' mean 'gironde' so perhaps 'department' could also mean 'gironde'). I am not certain of the 'wine' bit.
'good press extremely desirable' is the wordplay.
'good' becomes 'g' (abbreviation).
'press' becomes 'iron' (ironing is a kind of pressing).
'extremely' says to hollow out the word (remove centre letters) (only the extremes of the word are used).
'desirable' with its centre taken out is 'de'.
'g'+'iron'+'de'='GIRONDE'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for gironde that I've seen before include "French department around Bordeaux" , "Origin of claret" , "French river" , "Region of France" .)
