Make certain. No right to follow (5)
I believe the answer is:
ensue
'to follow' is the definition.
(ensue can mean to follow or happen as a result)
'make certain no right' is the wordplay.
'make certain' becomes 'ensure' (synonyms).
'no' suggests deleting specific letters.
'right' becomes 'r' (common abbreviation).
'ensure' with 'r' taken out is 'ENSUE'.
(Other definitions for ensue that I've seen before include "Transpire" , "Result in a particular way" , "Proceed" , "Happen as a result, follow ( 5)" , "Occur afterwards" .)
