Didn't see crashes en route (8)
I believe the answer is:
destined
'didn't see crashes en route' is the definition.
I can't judge whether this definition defines the answer.
'didn't see crashes' is the wordplay.
'crashes' indicates anagramming the letters.
'didnt'+'see'='didntsee'
'didntsee' is an anagram of 'DESTINED'.
Can you help me to learn more?
(Other definitions for destined that I've seen before include "Didn't see, being fated" , "Intended; doomed" , "Fated, fore-ordained" , "Intended (for a particular end)" , "Designated" .)
