In one way, fresh (3)
I believe the answer is:
new
'fresh' is the definition.
(I know that fresh can be written as new)
'in one way' is the wordplay.
'in' indicates a hidden word.
'NEW' is hidden in the letters of 'one way'.
(Other definitions for new that I've seen before include "Fresh, recent" , "Seen for the first time" , "Fresh, unused" , "Unfamiliar, restored" , "Unused or novel" .)
