Glue, for example (8)
I believe the answer is:
adhesive
'glue for example' is the definition.
(glue is a kind of adhesive)
This is the entire clue.
(Other definitions for adhesive that I've seen before include "Tacky" , "Sticky; glue" , "Stuff that sticks" , "doing some bonding" , "Hide vase (anag)" .)
