Honest following row (5)
I believe the answer is:
frank
'honest' is the definition.
('frank' can be similar in meaning to 'honest')
'following row' is the wordplay.
'following' becomes 'f' (used when citing page numbers etc).
'row' becomes 'rank' (I've seen this before).
'f'+'rank'='FRANK'
(Other definitions for frank that I've seen before include "stamp" , "Old German" , "Without evasion" , "Open" , "Anne ---, diarist" .)
