Subsequently learn to abroad (5,2)
I believe the answer is:
later on
'subsequently' is the definition.
(subsequently means later on)
'learn to abroad' is the wordplay.
'abroad' is an anagram indicator.
'learn'+'to'='learnto'
'learnto' is an anagram of 'LATER ON'.
(Other definitions for later on that I've seen before include "in the future" , "In the fullness of time" , "At a subsequent time" , "Afterwards" , "'Subsequently, afterward (5,2)'" .)
