Pali sira (40)
According to Davids and Stede’s Pali-English Dictionary, Pali word sira refers to “head.” It is linguistically related to terms in other Indo-European languages such as Sanskrit śiras, śīan; Avesta sarō; Greek kαράρα (karára), κέρας (kéras), κρανίον (kraníon); Latin cerebrum; and Old High-German hirni. It is an offshoot of the Tamil root kaṭu (sharpness) through the transformation of kaṭu (sharpness) > kar > ṡíras > sira. The following words, related to Pali sira, also originate from the Tamil root kaṭu (sharpness).
