Rob mentioned that:
>Examples of inherently singular nouns are like man, house, boat.
>Examples of inherently plural nouns are: ants, leaves, cherries and raindrops.

>To indicate that the noun is the opposite of its inherent nature,
>the definite article 'o' (animate) or 'a' (inanimate) is replaced by the article) 'i'.

>o tloko     the man            i tloko      the men
>a petlepe the raindrops    i petlepe   the raindrop

What about indefinite nouns?  How would "a man" be differentiated from "some man" and how would "a raindrop" be differentiated from "some raindrops?"
