Questions & Answers about Na ga wani tsuntsu a sama.
Na here is a combined subject + tense marker.
- It marks 1st person singular (I)
- and also tells you the action is in the completed past (perfective).
So Na ga literally means something like "I (completed-past) saw", but in English we just say "I saw" or sometimes "I have seen", depending on context.
Yes, Hausa has an independent pronoun ni = "I / me".
- In normal sentences, Hausa usually uses the short subject form (here na) attached to the verb, so Na ga… is the default.
- Ni is used mainly for emphasis, contrast, or focus:
Ni na ga wani tsuntsu a sama.
I (and not someone else) saw a bird in the sky.
In a neutral sentence, Na ga wani tsuntsu a sama is the natural choice.
