Sanskrit áṡri
In Monier-Williams’ A Sanskrit-English Dictionary, he states that áṡri, aṡáni, and aṡma are derived from the Sanskrit root aṡ (1), meaning “to reach, come to, arrive at, get, gain, obtain, to master, become master of, to offer, to enjoy, to pervade, penetrate, fill, and to accumulate.” He asserts that áṡri denotes “the sharp side of anything, corner, angle (of a room or house), edge (of a sword), often.” It has cognates in other Indo-European languages with a similar meaning. For instance, acies, acer in Latin, and assmû in Lithuanian are analogous to áṡri denoting “edge and sharp.” This Sanskrit áṡri traces its origin to the Tamil root akku through the transformation of akku > aṡ > áṡri (cf. k>c change, e.g., paku (to divide) > bhaj; puku (to enter) > bhuj). The following words, related to Sanskrit áṡri, also originate from Tamil akku.
