One way to be taken
I believe the answer is:
aback
'one way to be taken' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aback that I've seen before include "One is surprised when taken thus" , "To take someone -- is to surprise them" , "Sternwards" , "Towards the rear (arch.)" , "impeded by headwind?" .)
