Grammer
Nouns
The earliest record of the Heiban noun class system was composed by Stevenson (1956/57), in which he classified each noun class into two sections, the first being for singular form and the second for plural form. Each noun class has an indicative prefix. The separation of noun classes occurs due to the nouns belonging to a certain category. Guest (1997) further contributed to the findings of Stevenson by discovering more classification for nouns.
