Bore fit and lusty rogue (8)

I believe the answer is:

stultify

I'm a little stuck... Click here to teach me more about this clue!

'bore fit and lusty rogue' is the definition.
I can't judge whether this definition defines the answer.

'fit and lusty rogue' is the wordplay.
'and' means one lot of letters go next to another.
'rogue' is an anagram indicator (letters go rogue).
'fit' after 'lusty' is 'lustyfit'.
'lustyfit' is an anagram of 'STULTIFY'.

Can you help me to learn more?

(Other definitions for stultify that I've seen before include "Dull the mind with tedious tasks" , "Make useless" , "Make futile" , "Cause to appear stupid" , "Render ineffectual - lusty fit (anag)" .)
