Put off by man not closing washing up liquid? (5)
I believe the answer is:
deter
'put off' is the definition.
(both can mean to discourage)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for deter that I've seen before include "stop" , "Hinder, prevent" , "Frighten off; prevent" , "Put (someone) off" , "Discourage (an activity)" .)
