"Mother, I am starting!"

Translation: Mama, ninaanza!

[ElDoctr]

Swahili speakers often leave off "ni" when the meaning is clear. I believe this is only for first person

[vtopphol]

Yes, this is for first person singular only in present tence. There is however a gnomic tense with the same first person singular form as the shortened present tence.

[syntyche1981]

What is a gnomic tense?

[AGreatUserName]

It's a verb form that's used for "timeless" or "tenseless" situations, such as things that are always true or eternal.

[s.rombaut]

Why also naanza? you cant know the person right?

[vtopphol]

It's just a shortened form of ninaanza. Still 1st person singular present tense.
