Finished tango, glaring (5)
I believe the answer is:
overt
'glaring' is the definition.
(thesaurus)
'finished tango' is the wordplay.
'finished' becomes 'over' (over can mean finished or ended).
'tango' becomes 'T' (phonetic alphabet: alpha, bravo, charlie etc.).
'over'+'t'='OVERT'
(Other definitions for overt that I've seen before include "Patent, evident" , "Open, not secret or hidden" , "Done in an obvious way" , "Open,up front" , "Not locked away" .)
