Hide vase that's broken? Here's glue (8)
I believe the answer is:
adhesive
'glue' is the definition.
(I've seen this before)
'hide vase that's broken?' is the wordplay.
'that's broken?' indicates an anagram.
'hide'+'vase'='hidevase'
'hidevase' with letters rearranged gives 'ADHESIVE'.
'here's' is the link.
(Other definitions for adhesive that I've seen before include "What a sticker" , "very clingy" , "It sticks things together" , "Sticky; glue" , "doing some bonding" .)
