Sojojin sun dawo.

The -n is a determiner ending that often gives the noun a more definite or specific sense.

• sojoji = soldiers
• sojojin = the soldiers / those soldiers

So in this sentence, sojojin refers to a specific group of soldiers, not just soldiers in general.

The singular is soja = soldier.

So the forms are:

• soja = soldier
• sojoji = soldiers
• sojojin = the soldiers

A useful thing to remember is that Hausa plurals are often not made in one simple regular way like English -s. You usually need to learn the singular and plural together.

sun is the subject marker used with a third-person plural subject in the perfective/completed form.

Here it matches sojojin because sojojin is plural.

So:

• sun = they, in this verbal pattern
• sun dawo = they returned / they have returned

It is not just a free-standing pronoun by itself. In sentences like this, it is part of the normal verbal structure.

Because in Hausa, a full noun subject is commonly followed by a subject marker before the verb.

So the structure is:

• Sojojin = the soldiers
• sun = plural subject marker
• dawo = returned / came back

That means Hausa often works like this:

• Musa ya dawo = Musa returned
• Aisha ta dawo = Aisha returned
• Sojojin sun dawo = The soldiers returned

Even when the subject is already named, Hausa still normally keeps the matching subject marker.

It can mean either, depending on context.

The form sun here is perfective/completed, so English may translate it as:

• they returned
• they have returned
• sometimes even they came back

Hausa does not always match English tense choices one-for-one, so context decides the most natural translation.

dawo means to return, to come back, or to go back, depending on context.

In this sentence it is intransitive, meaning it does not take a direct object:

• sun dawo = they returned / they came back

There is also a related expression:

• dawo da ... = bring ... back

So dawo by itself is return, while dawo da means bring back.

Yes, you may hear that, but the nuance changes.

• sojoji = soldiers
• sojojin = the soldiers / the specific soldiers

So:

• Sojoji sun dawo can sound more general: soldiers have returned
• Sojojin sun dawo sounds more specific: the soldiers have returned

In your sentence, the -n suggests a known or identifiable group.

Yes. This is a very normal Hausa clause pattern:

Subject + subject marker + verb

So here:

• Sojojin = subject
• sun = subject marker
• dawo = verb

This pattern is extremely common in Hausa.

A rough English-friendly pronunciation is:

soh-JOH-jin soon DAH-wo

A few helpful notes:

• j sounds like the j in jam
• dawo has two clear syllables: da-wo
• sun is pronounced with a short vowel, roughly soon, but not as long as English soon

Also, Hausa is a tonal language, but tone is usually not written in ordinary spelling, so beginners usually learn pronunciation by listening as well as reading.

Not exactly.

• su is the independent pronoun: they / them
• sun is the form used before the verb in this perfective-type structure

So in this sentence, sun is the correct form, not su.

A beginner-friendly way to think of it is:

• su = standalone they
• sun = they when attached to this kind of verb phrase

No. In this sentence, gender is not shown.

That is because the subject is plural:

• sojojin = the soldiers
• sun = they

In Hausa, third-person singular often shows gender distinctions, but plural forms like sun do not. So this sentence could refer to male soldiers, female soldiers, or a mixed group, depending on context.
