Turkish official that is upset about very loud curtains (7)
I believe the answer is:
effendi
'turkish official' is the definition.
(I've seen this before)
'that is upset about very loud curtains' is the wordplay.
'that is' becomes 'ie' (short for Latin 'id est', 'that is').
'upset' shows that the letters should be reversed in order.
'about' means one lot of letters goes inside another.
'very loud' becomes 'ff' (musical abbreviation).
'curtains' becomes 'end' (I've seen this in another clue).
'ie' in reverse letter order is 'ei'.
'ff'+'end'='ffend'
'ei' going around 'ffend' is 'EFFENDI'.
(Other definitions for effendi that I've seen before include "Old Turkish title of respect for government officials" , "Eastern Mediterranean honorific" , "respectable address" , "Turkish address now comparable to 'Mr'" , "Turkish man respectfully" .)
