Restrain the workers to show affection? (4,5)
I believe the answer is:
hold hands
'show affection?' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'restrain the workers' is the wordplay.
'restrain' becomes 'hold' (synonyms).
'the workers' becomes 'hands' (hand is a kind of worker).
'hold'+'hands'='HOLD HANDS'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for hold hands that I've seen before include "What partners do" , "in bridge with two hearts in play?" .)
