Like to get first-class return for the continent (4)
I believe the answer is:
asia
'the continent' is the definition.
(Asia is an example)
'like to get first-class return' is the wordplay.
'like' becomes 'as'.
'to get' says to put letters next to each other.
'first class' becomes 'ai' (A1 - top quality).
'return' is a reversal indicator.
'ai' reversed gives 'ia'.
'as'+'ia'='ASIA'
'for' is the link.
(Other definitions for asia that I've seen before include "Tigers found here" , "group of countries" , "Heavily populated area" , "Part of the world" , "A is A (anag)" .)
