accusative singular masculine of niraya (noun)
Analysis. nis (away from, out of) + aya (going) — a state one has gone into or fallen away from the human realm into.
Etymology. nis + √i (go). The prefix nis (out of, away from) combines with the root for motion to suggest a realm one descends into and becomes trapped away from the world of humans and devas. No direct cognates in English or Latin, but the spatial imagery of falling away is cognate with English nether (descended realm).
