Girl going round in a man's hat (8)

I believe the answer is:

samantha

I'm a little stuck... Click here to teach me more about this clue!

'girl' is the definition.

'going round in a man's hat' is the wordplay.
'a man's hat' anagrams to 'SAMANTHA'.
However, I am unsure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for samantha that I've seen before include "Girl that scores" , "Girl's name" .)
