Overawe naïf, going back to disguise it again, in a different way (4)
I believe the answer is:
anew
'in a different way' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for anew that I've seen before include "Afresh" , "Once more (poetic)" , "From the beginning again" , "Again but differently" , "Wane in a different way, again" .)
