Cheat, in error, playing for cash (7)
I believe the answer is:
busking
'cheat in error playing' is the definition.
The definition suggests a present participle verb which matches the answer.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for busking that I've seen before include "Performing in the street for money" , "providing entertainment for commuters?" , "Playing street music" , "performing for donations" , "Serenading passers-by" .)
