'Doctor Strange' — I'm watching online (9)
I believe the answer is:
streaming
'watching online' is the definition.
I can't tell whether this defines the answer.
'doctor strange i'm' is the wordplay.
'doctor' is an anagram indicator.
'strange'+'im'='strangeim'
'strangeim' is an anagram of 'STREAMING'.
Can you help me to learn more?
(Other definitions for streaming that I've seen before include "going in large quantities" , "moving en masse" , "Way of classifying the children" .)
