Said to have been positioned in a rush (7)
I believe the answer is:
reputed
'said' is the definition.
(thesaurus)
'positioned in a rush' is the wordplay.
'positioned' becomes 'put' (I've seen this in another clue).
'in' is an insertion indicator.
'a rush' becomes 'reed' (I've seen this in other clues).
'put' put inside 'reed' is 'REPUTED'.
'to have been' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for reputed that I've seen before include "Generally believed (to be the case)" , "Generally believed to exist" , "Rumoured, reckoned" , "Considered" , "Alleged" .)
