Questions & Answers about Ni zan amsa tambaya yanzu.
Ni is the independent pronoun meaning I / me.
The future marker za already carries a subject pronoun, so zan by itself means I will. That means:
- Zan amsa tambaya yanzu. = I will answer the question now.
- Ni zan amsa tambaya yanzu. = I will answer the question now (with extra emphasis on I).
So you do not have to say ni; it is grammatically optional and mainly adds emphasis or contrast (for example: Not you, I will answer the question now).
Zan is the future marker za combined with the pronoun ni (I):
- za + ni → zan
So zan amsa literally means I‑will answer.
Other persons in the future usually keep za and the pronoun separate (except for zai, which is very common):
- I: zan (za + ni) – I will
- you (m sg): za ka – you will
- you (f sg): za ki – you will
- he: zai (za + shi / ya) – he will
- she: za ta – she will
- we: za mu – we will
- you (pl): za ku – you (pl) will
- they: za su – they will
