Button's quicker taking English pole (8)
I believe the answer is:
fastener
'button's' is the definition.
(thesaurus)
'quicker taking english pole' is the wordplay.
'quicker' becomes 'faster' ('faster' can be a synonym of 'quicker').
'taking' is an insertion indicator.
'english' becomes 'e' (abbreviation).
'pole' becomes 'n'.
'e'+'n'='en'
'faster' placed around 'en' is 'FASTENER'.
(Other definitions for fastener that I've seen before include "Pin, popper or zip, perhaps" , "Clip, catch, etc" , "Fixer, securer" , "Clip, catch or other means of fixing securely" , "It could secure" .)
