Set up English duke to take Crete break (7)
I believe the answer is:
erected
'set up' is the definition.
(I've seen this before)
'english duke to take crete break' is the wordplay.
'english' becomes 'e' (abbreviation).
'duke' becomes 'd' (abbreviation).
'to take' is an insertion indicator.
'break' is an anagram indicator.
'e'+'d'='ed'
'crete' is an anagram of 'recte'.
'ed' placed around 'recte' is 'ERECTED'.
(Other definitions for erected that I've seen before include "Set up" , "Fixed up" , "No Clue" , "Put up (a building)" , "Constructed, built" .)
