"Mto una maji mazuri"

Translation: A river has good water

[s.rombaut]

Why una?

[likes2hike]

The subject prefix must agree with the noun. 'Mto' is a MI- class noun (plural 'mito'), and so takes the 'u-' subject prefix in the singular. With practice, the patterns start to come more naturally. :)

[Ruben_in_Moss]

Una is also "you have", right?

[iongantas]

A single instance does not a pattern make.

[s.rombaut]

Will they give the pattern of those verbs?

[iongantas]

river, you have good water

isn't una you have? shouldn't it be ana if it mean it has?

[likes2hike]

Yes, "una" means "you have," but it also means "(it) has" for MI- class nouns such as maji. "Ana" means "he/she has."
