Follow scholar's teaching (5)
I believe the answer is:
dogma
'teaching' is the definition.
(dogma is a kind of teaching)
'follow scholar's' is the wordplay.
'follow' becomes 'dog' (I've seen this before).
'scholar' becomes 'ma'.
'dog'+'ma'='DOGMA'
(Other definitions for dogma that I've seen before include "fixed opinion" , "Article of faith" , "Inflexible principle" , "Tenet" , "Some believe it certainly" .)
