That zhig, a “heteronomous particle” (phrad gzhan dbang can), can be used in the sense of (a) an indefinite article “a, an” or “one” (cf. gang zhig “a certain”) and (b) an imperative particle (skul tshig ston byed kyi tshig) is perhaps clear to us. But what is perhaps less clear is its (c) “nominalizing function,” which may be rendered as “one that is,” “those that are,” “that which is,” “that which are,” and so on.
