दुर्गसिंह the famous commentator of the Katantra sutras, whose Vrtti on the sutras is the most popular one. It is called , कातन्त्रसूत्रवृत्ति or कातन्तवृत्ति or दौर्गसिंहीवृत्ति , also. A work on Paribhasas named परिभाषा- वृति, in which Paribhasas are ex- plained and established as based on the Katantra Vyakarana sutras, is attributed to Durga- simha. It is doubtful whether this commentator Durgasimha is the same as Durgacarya, the famous commentator of Yaska's Nirukta. There is a legend that Durgasimha was the brother of Vikramaditya, the founder of the Vikrama Era. Besides the gloss on the Katantra sutras, some gra- mmar works such as a gloss on the unadi sutras, a gloss ( वृत्ति ) on Kalapa-Vyakarana Sutras, a com- mentary on Karakas named षट्का- रकरत्न, Namalinganusasana and Paribhasavrtti are ascribed to Durgasimha. Some scholars be- lieve that the term अमरसिंह was only a title given to Durgasimha for his profound scholarship, and it was Durgasimha who was the author of the well-known work Amarakosa.
