Worry European drivers will go wrong way (4)
I believe the answer is:
care
'worry' is the definition.
(eg without a care means without a worry)
'european drivers will go wrong way' is the wordplay.
'european' becomes 'e' (abbreviation e.g. EU).
'drivers will' becomes 'rac' (I can't justify this - if you can you should give a lot more credence to this answer).
'go wrong way' says the letters should be written in reverse (I've seen 'going wrong way' mean this).
'e'+'rac'='erac'
'erac' reversed gives 'CARE'.
Can you help me to learn more?
(Other definitions for care that I've seen before include "Consideration" , "Be concerned or nurse" , "The provision of what's necessary, for health say" , "Worry" , "Attention - caution U protection" .)
