Sanskrit Rādhā derives from √rādh, "to prosper, accomplish, propitiate" — Monier-Williams glosses the word as prosperity and success, and records her celestial namesake: the nakshatra Viśākhā is also called Rādhā. The restoration Rādhā keeps both long vowels exactly where the Sanskrit puts them; the ASCII "Radha" flattens the two syllables the tradition holds long. Tier-1 by rule: two macrons preserved.
