Shot at first allure (7)
I believe the answer is:
attempt
'shot' is the definition.
(thesaurus)
'at first allure' is the wordplay.
'first' says to put letters next to each other.
'allure' becomes 'tempt' ('tempt' can be a synonym of 'allure').
'at'+'tempt'='ATTEMPT'
(Other definitions for attempt that I've seen before include "Essay" , "Endeavor, try" , "Try to climb (a peak)" , "bid to kill someone" , "Try, hazard" .)
