Worker so very loud? Keep away! (5,3)
I believe the answer is:
hands off
'keep away' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'worker so very loud?' is the wordplay.
'worker' becomes 'hand' (hand is a kind of worker).
'very loud?' becomes 'ff' (musical abbreviation).
'hand'+'so'+'ff'='HANDS-OFF'
Can you help me to learn more?
(Other definitions for hands off that I've seen before include "Don't interfere" , "Don't touch!" , "Not getting involved" , "Operated by remote control" .)
