One had crashed - in this way? (4-2)
I believe the answer is:
head-on
'in this way?' is the definition.
Both the answer and definition are adverbs. Maybe you can see a link between them that I can't see?
'one had crashed' is the wordplay.
'crashed' indicates anagramming the letters.
'one'+'had'='onehad'
'onehad' anagrammed gives 'HEAD-ON'.
Can you help me to learn more?
(Other definitions for head-on that I've seen before include "One had (anag.)" , "This collision is full frontal" , "In direct opposition" , "Of car crash, full frontal" , "(Of crash) involving the front of vehicle)" .)
