Rubbish match official getting us embittered at first (6)
I believe the answer is:
refuse
'rubbish match' is the definition.
'refuse' can be an answer for 'rubbish' (thesaurus). I am unsure of the 'match' bit.
'official getting us embittered at first' is the wordplay.
'official' becomes 'ref' (match official in football, say).
'getting' means one lot of letters go next to another.
'at first' says to take the initial letters.
The first letter of 'embittered' is 'e'.
'ref'+'us'+'e'='REFUSE'
Can you help me to learn more?
(Other definitions for refuse that I've seen before include "Say no to garbage" , "Decline to accept - rubbish" , "litter" , "Decline to take the rubbish" , "Decline, repudiate" .)
