Puzzled personnel in urban area (6)
I believe the answer is:
thrown
'puzzled' is the definition.
(thesaurus)
'personnel in urban area' is the wordplay.
'personnel' becomes 'HR' (Human Resources).
'in' is an insertion indicator.
'urban area' becomes 'town' (town is a kind of urban area).
'hr' placed inside 'town' is 'THROWN'.
(Other definitions for thrown that I've seen before include "Unseated" , "Defeated" , "given up intentionally" , "Having been projected through the air" , "Hurled, flung" .)
