Crazy motorway driver, see - precisely! (8)
I believe the answer is:
minutely
'precisely' is the definition.
(I've seen this before)
'crazy motorway driver see' is the wordplay.
I cannot really see how this works, but
'crazy' could be 'nut' (I've seen this before) and 'nut' is found in the answer.
'motorway' could be 'mi' (resembles M1, English motorway) and 'mi' is located in the answer.
'see' could be 'ely' (see is a place with a cathedral - e.g. Ely) and 'ely' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for minutely that I've seen is " Precisely".)
