Nearly no good, nearly type nothing (5)
I believe the answer is:
nihil
'nothing' is the definition.
('nihil' means 'nothing' in Latin)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for nihil that I've seen before include "'... obstat' - Catholic imprimatur or approval" , "Nothing (Latin)" , "love" .)
