Girl transported by aliens (6)

I believe the answer is:

selina

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

'girl' is the definition.

'transported by aliens' is the wordplay.
'aliens' anagrams to 'SELINA'.
However, I'm not clear how the anagram is indicated.

Can you help me to learn more?

(Other definitions for selina that I've seen before include "A woman" , "Girl" .)

I've seen this clue in the Evening Standard.
