Questions & Answers about Hukumar ta duba shaida sannan ta ba ni izini.
Hukuma is the basic noun, while Hukumar is the definite form, roughly the agency / the authority.
In Hausa, definiteness is often shown with an ending such as -r or -n. Because hukuma is a feminine noun, it takes -r, giving hukumar.
So Hukumar here means something like the agency rather than just an agency.
In Hausa, a finite verb normally needs a preverbal subject marker. Here, ta is the marker used for 3rd person singular feminine in the completive aspect.
So Hukumar ta duba is literally structured more like:
the agency + it + checked
That may feel redundant to an English speaker, but it is normal Hausa grammar.
Because there are two verb phrases:
- ta duba shaida
- ta ba ni izini
Each clause needs its own subject marker, so ta appears again before the second verb. Both ta forms refer back to Hukumar.
