Without any breaks? That's no French way to work (7)
I believe the answer is:
nonstop
'without any breaks?' is the definition.
I can't judge whether this defines the answer.
'no french way to work' is the wordplay.
'no french' becomes 'non' ('no' in French).
'way' becomes 'st' (abbreviation for street).
'to work' becomes 'op' (abbreviation for opus).
'non'+'st'+'op'='NONSTOP'
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for nonstop that I've seen before include "Done without pause" , "Incessant" , "Continuous, without pause" , "Relentless" , "(Of a flight) direct" .)
