Responsibility each Argentinian carries (6)
I believe the answer is:
charge
'responsibility' is the definition.
(thesaurus)
'each argentinian carries' is the wordplay.
'carries' says the answer is hidden in the clue.
'CHARGE' is hidden within 'each argentinian'.
(Other definitions for charge that I've seen before include "Do as the Light Brigade did" , "15 - or required payment" , "offensive, > explosive > tax" , "running cost" , "Sortie" .)
