Endless garbage? Take 50% of that to power (7)
I believe the answer is:
nonstop
'endless' is the definition.
(thesaurus)
'garbage? take 50 of that to power' is the wordplay.
I cannot quite see how this works, but
'of' could be 'o' and 'o' is located in the answer.
'to' is within the answer.
'power' could be 'p' and 'p' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for nonstop that I've seen before include "(Of a flight) direct" , "Incessant" , "Continuous, without pause" , "Around-the-clock" , "without rest" .)
