Call in Latin America (4)
I believe the answer is:
name
'call' is the definition.
(as in calling or naming someone something)
'in latin america' is the wordplay.
'in' indicates a hidden word.
'NAME' is hidden within 'latin america'.
(Other definitions for name that I've seen before include "Handle" , "Mean sort of appellation" , "By which one is known" , "Moniker" , "Call; reputation" .)
