काशिका वृत्ति (आचार्य वामन एवं जयादित्य - अष्टाध्यायी सूत्र-वृत्ति सम्पूर्ण सान्वय सटीक)

? No. Let's read the text of Kashika 4.1.78 in standard editions: "गोत्रे यावञिञौ विहितावनानार्षौ तदन्तयोः प्रातिपदिकयोर्गुरूपोत्तमयोः स्त्रियां ष्यङादेशो भवति।" Wait! Does Kashika say "विहितावनानार्षौ"? Wait! Why would it say "विहितावनानार्षौ"? Wait, is it "विहिताव् अनार्षौ" or "विहितावनानार्षौ"? Wait! Could it be "विहिताव्" + "अनानार्षौ"? Why "अनानार्षौ"? "अ-नानार्षौ"?? Double negative? Wait, or is it a typo in this printed edition: विहितावनानार्षौ? Look at the image in line 17: वि-हि-ता-व-ना-ना-र्षौ! YES! There are literally TWO नाs in the print! Look: वि हि ता व ना ना र्षौ! Wait, let's look at both: First ना: has a loop, horizontal bar, vertical stem. Second ना: has a loop, horizontal bar, vertical stem, with र्andौon top:र्षौ`!
