Take courses perhaps in English after row (4)
I believe the answer is:
dine
'take courses perhaps' is the definition.
(as in courses of a meal)
'english after row' is the wordplay.
'english' becomes 'e' (abbreviation).
'after' says to put letters next to each other.
'row' becomes 'din' (both can mean a loud disturbance).
'e' put after 'din' is 'DINE'.
'in' is the link.
(Other definitions for dine that I've seen before include "Have an evening meal" , "Take meal" , "Take dinner" , "Feed" , "Have supper" .)
