Show I acted wrongly in the beginning (8)
I believe the answer is:
indicate
'show' is the definition.
(I know that show can be written as indicate)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for indicate that I've seen before include "Point out, make known" , "Point, show, signal" , "Make a signal" , "Point out or give some notion of" , "Point out, suggest" .)
