Sharhin yana da amfani.

A helpful breakdown is:

• Sharhin = the comment / the explanation / the review
• yana = a present/imperfective marker agreeing with a masculine singular subject
• da = with / having
• amfani = use / benefit / usefulness

So the sentence is literally something like:

The comment/explanation, it has usefulness.

That is why the natural English meaning is The comment/explanation is useful.

Yes, from an English point of view it can feel repetitive, but this is normal in Hausa.

With a full noun subject, Hausa very often also uses a matching subject pronoun/aspect marker in the clause:

• Sharhin yana da amfani
• literally: The explanation, it has usefulness

This is a standard Hausa pattern, not an error and not extra emphasis by itself.

English usually says:

• The explanation is useful

But Hausa commonly says the equivalent of:

• The explanation, it is useful

The -n here marks the noun in its definite form, so sharhin means the comment/explanation/review, not just a comment/explanation in a general sense.

So:

• sharhi = comment / explanation / review
• sharhin = the comment / the explanation / the review

For a learner, the easiest way to understand it here is: the sentence is talking about a specific, identifiable comment or explanation.

Yana is the form used for a masculine singular subject in the present/imperfective pattern.

In this sentence, the subject sharhin is treated as masculine singular, so Hausa uses yana.

You can think of it as carrying ideas like:

• it is
• it has
• present-time predication for a masculine singular subject

Very importantly, this is grammatical gender, not biological sex. Even inanimate nouns in Hausa are grammatically masculine or feminine.

If the noun were feminine, you would typically see tana instead.

Because Hausa often expresses qualities in ways that are different from English.

Here, amfani is a noun meaning use, benefit, usefulness. So:

• yana da amfani
• literally: it has usefulness / it has benefit

That is the Hausa way of saying it is useful.

So instead of using a simple adjective exactly like English useful, Hausa often uses a structure with da plus a noun.

It can be understood as both, depending on how literally you want to read it.

In many Hausa sentences, da has the sense of:

• with
• having

So:

• yana da anfani/amfani
  = it has benefit/usefulness = it is useful

This is a very common Hausa pattern. English translates it naturally with is, but Hausa builds the meaning through yana da + noun.

There is no single separate word here that matches English is exactly.

Hausa does not always use to be the same way English does. In this sentence, the idea of is useful is expressed by the whole structure:

• yana da anfani/amfani

So instead of looking for one word that equals is, it is better to learn the whole pattern:

• X yana da Y = X has Y / X is Y-like in that way

Here:

• Sharhin yana da amfani = The explanation is useful

It can mean several related things, depending on context.

Common possibilities include:

• comment
• explanation
• commentary
• review
• annotation

So the best English translation depends on what kind of text or situation you are talking about. In one context it may be The comment is useful, while in another it may be The explanation is useful or The review is useful.

A rough learner-friendly pronunciation is:

SHAHR-hin YA-na da am-fa-NI

A few points:

• sh sounds like English sh in shop
• the h is pronounced
• r is usually a light tap or flap, not a heavy English r
• yana is roughly YA-na
• amfani is roughly am-fa-NI

If you want to sound more natural, pay attention to rhythm and listen to native audio, because Hausa tone and vowel length also matter.

A common way is:

Sharhin ba shi da amfani.

This means:

• Sharhin = the comment/explanation
• ba shi da = does not have / is not with
• amfani = use / usefulness

Literally:

The comment does not have usefulness.

Natural English:

The comment is not useful.

Notice that the affirmative pattern yana da changes in the negative to ba shi da for a masculine singular subject.
