Pali sara (12)
Davids and Stede’s Pali-English Dictionary says Pali word sara means “the reed Saccharum sara and an arrow originally made of that reed.” It also shares etymological relationship with the Vedic word śara. However, it traces its origin to the Tamil root kaṭu (sharpness) through the transformation of kaṭu (sharpness) > kar > ṡará > sara. The following words, related to Pali sara, also originate from Tamil kaṭu (sharpness).
