Sporty enough to cause a car crash, some day (4)
I believe the answer is:
racy
'crash some day' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?
'sporty enough to cause a car' is the wordplay.
'sporty enough' becomes 'y' (I can't explain this - if you can you should give a lot more credence to this answer).
'to' says to put letters next to each other (I've seen this in other clues).
'cause' indicates anagramming the letters.
'car' with letters rearranged gives 'rac'.
'y' after 'rac' is 'RACY'.
Can you help me to learn more?
(Other definitions for racy that I've seen before include "Sexually suggestive" , "Lively" , "Suggestive, risque" , "bawdy quality" , "Spicy" .)
