To prejudice Smollett, for instance (6)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
tobias
'smollett for instance' is the definition.
(poet Tobias Smollett is an example)
'to prejudice' is the wordplay.
'prejudice' becomes 'bias' (biasing is a kind of prejudicing).
'to'+'bias'='TOBIAS'
(Other definitions for tobias that I've seen before include "Biblical man" , "Boy" , "-- Smollett, novelist" .)
