Send a message in it, extraordinarily (4)

I believe the answer is:

text

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

'send a message' is the definition.
I can't tell whether this definition defines the answer.

'in it extraordinarily' is the wordplay.
'in' indicates a hidden word.
'TEXT' is hidden in the letters of 'it extraordinarily'.

Can you help me to learn more?

(Other definitions for text that I've seen before include "Use phone" , "Send a written message by phone" , "Wording" , "Script" , "Contact" .)

I've seen this clue in The Telegraph.
