Excerpt from Antonioni's domestic tear-jerker? (5)

I believe the answer is:

onion

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

'tear-jerker?' is the definition.
(cutting onions can make you cry)

'excerpt from antonioni's domestic' is the wordplay.
'ONION' is hidden within the letters.
But, I'm not sure how this is indicated.

Can you help me to learn more?

(Other definitions for onion that I've seen before include "Strong tasting vegetable" , "Shape of Russian dome" , "it can bring tears" , "Eye-watering vegetable" , "Plant with edible bulb" .)

I've seen this clue in The Guardian.
