Negative duo that won't bond on record is entering retreat (4,4)
I believe the answer is:
lone pair
'negative duo that won't bond' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'on record is entering retreat' is the wordplay.
'record' becomes 'EP' (abbreviation for extended play record).
'is entering' is an insertion indicator.
'retreat' becomes 'lair' (both can mean a private hideout).
'on'+'ep'='onep'
'onep' going within 'lair' is 'LONE PAIR'.
Can you help me to learn more?
I've seen this clue in The Guardian.
