In one way, very original (3)
I believe the answer is:
new
'original' is the definition.
(similar in meaning)
'in one way very' is the wordplay.
'in' indicates the answer is hidden within the clue.
'NEW' is hidden in the letters of 'one way very'.
(Other definitions for new that I've seen before include "Contemporary" , "Original" , "'Fresh, novel (3)'" , "Unused or novel" , "Not existing before" .)
