Clever enough to seem right, in recalcitrant fault (6)
I believe the answer is:
artful
'clever' is the definition.
(similar in meaning)
'right in recalcitrant fault' is the wordplay.
'right' becomes 'r' (common abbreviation).
'in' means one lot of letters goes inside another.
'recalcitrant' indicates anagramming the letters.
'fault' anagrammed gives 'atful'.
'r' going within 'atful' is 'ARTFUL'.
'enough to seem' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for artful that I've seen before include "Cunning, wily" , "Dickens boy, an . . . . . . Dodger" , "Crafty like Dicken's Dodger" , "Crafty or cunning" , "Giving a false appearance of frankness" .)
