Put up with assistant hogging bottle opener (5)
I believe the answer is:
abide
'put up with' is the definition.
(synonyms)
'assistant hogging bottle opener' is the wordplay.
'assistant' becomes 'aide' (aide is a kind of assistant).
'hogging' means one lot of letters goes inside another.
'opener' says to take the initial letters.
The initial letter of 'bottle' is 'b'.
'aide' placed around 'b' is 'ABIDE'.
(Other definitions for abide that I've seen before include "Accept" , "Hack" , "'. . . . . with me, fast falls the eventide'" , "Bear, endure" , "brook" .)
