Start being slightly confused (5)
I believe the answer is:
begin
'start' is the definition.
(I know that start can be written as begin)
'being slightly confused' is the wordplay.
'being' can be anagrammed to 'BEGIN'.
However, I'm not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for begin that I've seen before include "Initiate" , "Launch" , "Commence" , "Found" , "Clandestine, furtive" .)
