Involved with Spinner? Precisely not! (4)
I believe the answer is:
into
'involved with' is the definition.
(I've seen this before)
'spinner? precisely not' is the wordplay.
'spinner? precisely' becomes 'int' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'not' becomes 'o' (I've seen this in other clues).
'int'+'o'='INTO'
Can you help me to learn more?
(Other definitions for into that I've seen before include "digging" , "Enthusiastic about" , "ignition regularly missing" , "Expression of division" , "Knowledgeable about" .)
