Something intoxicating about kiss? A lot could turn on it (4)
I believe the answer is:
axle
'something intoxicating about kiss? a lot' is the definition.
I can't judge whether this definition defines the answer.
'turn on it' is the wordplay.
'turn' becomes 'axl' (I can't explain this - if you can you should give a lot more credence to this answer).
'on' says to put letters next to each other.
'it' becomes 'e' ('e' can mean 'electronic' which is similar to 'IT').
'axl'+'e'='AXLE'
'could' is the link.
Can you help me to learn more?
(Other definitions for axle that I've seen before include "Shaft with wheels attached" , "Rod to carry a wheel" , "Rotating spindle" , "Pin in revolver" , "Shaft on which wheels rotate" .)
