Stuns and ousts deviant (8)

Ross

I believe the answer is:

astounds

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

'stuns' is the definition.
Although both the answer and definition are verbs in their -s form, I can't understand how they can define each other.

'and ousts deviant' is the wordplay.
'deviant' indicates anagramming the letters.
'and'+'ousts'='andousts'
'andousts' anagrammed gives 'ASTOUNDS'.

Can you help me to learn more?

(Another definition for astounds that I've seen is " Amazes, astonishes".)

I've seen this clue in The Irish Times.
