Sinhalese aga
In his Sinhala English Dictionary, Clough asserts that the Sinhalese word aga refers to the “end, front, extremity, great depth, profundity, sorrow, distress, house, rock, stone, fear, body, fire, medicine, part, portion, sun, and snake, Cobra capella.” It also means “first, noble, principal, and chief.” It is an offshoot of Tamil akku through the transformation of akku > ágra > aga.
