Make a little love with a light touch (4)

I believe the answer is:

kiss

I'm a little stuck... Click here to teach me more about this clue!

'light touch' is the definition.
(kiss can mean to brush against lightly)

I don't understand the remainder of the clue.

Can you help me to learn more?

(Other definitions for kiss that I've seen before include "Cross" , "Gentle touch of the lips" , "Evidence of romance" , "Transient touch" , "Snog" .)
