Bidiyon yana da amfani.

The ending -n is a very common Hausa noun ending that often makes the noun definite or specific. So Bidiyon here is roughly the video or that specific video.

A simple way to think about it is:

• bidiyo = video / a video
• bidiyon = the video

You will often see this ending as -n or -r, depending on the noun.

It is similar in function, but not exactly the same as English is.

Hausa does not use one single verb that covers every case of English to be. In this sentence, yana is part of a very common pattern for describing a present state or quality:

noun + yana/tana + da + noun

So Bidiyon yana da amfani is literally close to:

The video has use/benefit

which English naturally expresses as The video is useful.

That is normal Hausa grammar. Even when the subject noun is already stated, Hausa often still uses a matching subject marker such as yana, tana, or suna.

So the structure is not strange in Hausa; it is just how the sentence is built.

You can break it down like this:

• Bidiyon = the video
• yana = it is / it has, matching a masculine singular noun in this pattern
• da anfani = with use/benefit

So yes, it may feel a bit like The video, it has benefit, but that is a normal Hausa structure.

Because bidiyo is treated as a masculine singular noun in Hausa.

Hausa nouns have grammatical gender, and the agreement word has to match the noun:

• yana = masculine singular
• tana = feminine singular
• suna = plural

So with bidiyo, the matching form is yana.

Here da is part of the pattern yana da / tana da / suna da, which often expresses having.

So:

• yana da littafi = he has a book
• yana da anfani = it has use/benefit

In this sentence, that whole idea is translated naturally as is useful.

So da here is not and. It is part of a possession-like structure.

No, amfani is basically a noun meaning use, benefit, usefulness.

That is why the sentence is literally something like:

The video has usefulness/benefit.

Hausa often expresses qualities this way instead of using a simple adjective in the same way English does.

So:

• literal sense: it has benefit
• natural English meaning: it is useful

Yes. That is a very common beginner confusion.

These two are different:

• yana da anfani = it is useful
• yana amfani da ... = he/she/it is using ...

The position of da is important:

• yana da anfani = has usefulness
• yana amfani da abu = is using a thing

So even though the words look similar, the meanings are different.

A common way is:

Bidiyon ba shi da anfani.

This is literally something like:

The video does not have usefulness.

Notice the pattern:

• positive: Bidiyon yana da anfani.
• negative: Bidiyon ba shi da anfani.

Yes, but it changes the feel a bit.

• Bidiyon yana da anfani sounds more like the video or that specific video
• Bidiyo yana da anfani sounds less clearly definite, more like a video or just video in a general sense

So if the meaning shown to the learner is The video is useful, the form Bidiyon makes very good sense.
