I believe the answer is:

disingenuous

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

'cunning as an adjective' is the definition.
I can't tell whether this definition defines the answer.

'cryptically disguise noun' is the wordplay.
'cryptically' indicates anagramming the letters.
'disguise'+'noun'='disguisenoun'
'disguisenoun' anagrammed gives 'DISINGENUOUS'.

Can you help me to learn more?

(Other definitions for disingenuous that I've seen before include "Not sincere" , "Insincere" .)
