One’s top performer in China, using false name, perhaps (10)
I believe the answer is:
misleading
'false name perhaps' is the definition.
I can't tell whether this definition defines the answer.
'one's top performer in china' is the wordplay.
'one's' becomes 'i's' (Roman numeral).
'top performer' becomes 'lead' (lead is a kind of performer. I am not sure about the 'top' bit.).
'in' is an insertion indicator.
'china' becomes 'ming' (Ming china is a type of porcelain).
'is'+'lead'='islead'
'islead' put inside 'ming' is 'MISLEADING'.
'using' is the link.
Can you help me to learn more?
(Other definitions for misleading that I've seen before include "Giving a wrong impression" , "Unreliable" , "Deceptive" , "Giving a false impression" , "pointing in the wrong direction" .)
