Dear Colleagues!

In the list of siddhas given in the Haṭhapradīpikā there appears the following line that is treated by all editions known to me as a single compound:

cauraṅgī-mīna-gorakṣa-virūpākṣa-bileśayāḥ (HP 1.5cd).

Now, if the first name would be regarded as having the theme cauraṅgin-, the form in a compound should be cauraṅgi-, of course. I wonder if this is a case of a vernacular form used in a Sanskrit compound, or if it is no compound at all and we have a regular Sanskrit nominative. Any help would be highly appreciated, especially cases of words with clearly vernacular endings in Sanskrit texts.

Best wishes,
Sven
