Its lingual analogue is the word Shūnyam.
It’s auditory analogue is the sound: ‘Silence!’ [You violate the silence in commanding: ‘Silence!’]

Shūnyam, the formal Sanskrit for Śūnya in common-speak, etymologically originate in the notion of hollowness, of ’empty inside’. The term ‘Empty’ as used in English translations of Shūnyam originates directly from the vocabulary of Classical Logic [as does the word ‘Form’ as used in the Heart Sutra].
