A little distraction from Corona -

कोरोनास्पर्शभीतोऽसौ पाणिनि: शब्दशास्त्रविद् ।
स्वीयव्याकरणस्यान्तेऽस्पृष्टं वर्णद्वयं जगौ ।।

Scared of the touch of Corona, the great grammarian Panini, at the very end of his grammar, uttered the "untouched" sounds "a a" [अ अ].

Note: According to phoneticians, the pronunciation of the vowel "a" [अ] has a completely clear vocal track with no contact of oral organs.
