Sanskrit rīti (7)
According to Monier-Williams’ A Sanskrit-English Dictionary, Sanskrit word rīti means “going, motion, course; a stream, current; a streak, line, row; limit, boundary; general course or way, usage, custom, practice, method, manner; natural property or disposition; style of speaking or writing, diction.” The word rīti is derived from the root ri, connoting “to release, set free, let go; to sever, detach from; to yield, bestow; and to be shattered or dissolved, melt, become fluid, drop, and flow.” It originates from the Tamil root aruvi, through the transformation of aruvi > ri > rīti.
