Thanks charity, say, for steps taken in Latin America? (5)
I believe the answer is:
tango
'for steps taken in latin america?' is the definition.
(as in dance steps)
'thanks charity' is the wordplay.
'thanks' becomes 'ta' (UK informal version of 'thank you').
'charity' becomes 'NGO' (charities are non-governmental organisations).
'ta'+'ngo'='TANGO'
'say' acts as a link.
(Other definitions for tango that I've seen before include "One from Argentina" , "Last - in Paris (film)" , "Rhythmic movement" , "Colourful dance from Argentina" , "Argentinian dance form" .)
