Speak for a technical insider (5)

I believe the answer is:

orate

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

'speak' is the definition.
(I know that orate is a more specific form of the action speak)

'for a technical insider' is the wordplay.
'ORATE' is hidden in amongst the letters.
But, I am unsure how the hidden word is indicated.

Can you help me to learn more?

(Other definitions for orate that I've seen before include "Speaker may" , "Make a lengthy speech" , "Make a formal address" , "Pontificate" , "Lecture" .)

I've seen this clue in the Sydney Morning Herald.
