Bond heard to move outside at last (6)
I believe the answer is:
adhere
'bond' is the definition.
(I know that bond can be written as adhere)
'heard to move outside at last' is the wordplay.
'to move' is an anagram indicator.
'at last' suggests the final letters.
The final letter of 'outside' is 'e'.
'heard' anagrammed gives 'adher'.
'adher'+'e'='ADHERE'
(Other definitions for adhere that I've seen before include "paste" , "Stick to - cement" , "Stay attached" , "Stick L" , "Stick with header" .)
