Note that ra may be taken as a postposition of the genitive as well as phonetic complement (see on line 3).
The accusative case in nouns is marked by a postposition, ku, as in Hindustani.
The postposition pampa, ixtli, the face, and the first possessive pronoun no.
If ra were a postposition, it would follow the suffix bi (on which see Hymn to Sin, line 27).
When the noun to which they are suffixed has a double form, the postposition is added to the short form.
