Dear Sanskritists,

I haven't been able to find a reference in Pāṇini grammar for a verse utilising a grammatical pun. The pun involves turning ma into sa.

Our teachers are indeed the most accomplished grammarians

who can substitute equality (samatā) for ownership (mamatā),
turning mamatā into samatā.
They have the best grammar.

सुतरां गुरवोऽस्माकं वैयाकरणसत्तमाः ।
आदिश्य ममतास्थाने समतां साधयन्ति ये ॥९॥

sutarāṁ guravo'smākaṁ vaiyākaraṇasattamāḥ |
ādiśya mamatāsthāne samatāṁ sādhayanti ye ||9||

I would be grateful for any help.
Many thanks,
