Sound way to make friends! (5)
I believe the answer is:
click
'sound' is the definition.
(click is a kind of sound)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for click that I've seen before include "Be compatible" , "come down on mouse" , "One can with mouse, too" , "Depress the button on a camera" , "Kind of beetle" .)
