Musa bai dawo daga wurin wanzami ba tukuna.

This is the normal Hausa way to make this kind of clause negative.

In this sentence, bai ... ba means did not / has not around the verb phrase:

• bai dawo ba = he did not return / he has not returned

So the negation is discontinuous: one part comes before the verb, and ba comes later.

Compare:

• Musa ya dawo. = Musa returned / has returned.
• Musa bai dawo ba. = Musa did not return / has not returned.

With tukuna, the meaning becomes has not returned yet.

Bai is the negative form used here for 3rd person singular masculine—that is, he.

Since Musa is grammatically masculine, Hausa uses:

• ya in the affirmative
• bai ... ba in the negative

So:

• Musa ya dawo = Musa returned
• Musa bai dawo ba = Musa did not return

If the subject were feminine, Hausa would use a different form:

• Aisha ta dawo = Aisha returned
• Aisha ba ta dawo ba = Aisha did not return

In Hausa, it is very normal for a full noun subject like Musa to be followed by a subject marker before the verb.

So Hausa often works like:

• Musa ya dawo
• Musa bai dawo ba

Even though Musa already tells you who the subject is, Hausa still uses the appropriate subject marker. This is a basic and very common feature of Hausa sentence structure.

Dawo means return, come back, or come again, depending on context.

In this sentence, dawo is best understood as:

• return
• come back

So:

• bai dawo ba tukuna = has not come back yet

A useful contrast is:

• zo = come
• dawo = come back / return
• tafi = go

So dawo includes the idea of coming back from somewhere.

Literally, it means from the place of the barber.

Breakdown:

• daga = from
• wurin = place of / at the place of
• wanzami = barber

So daga wurin wanzami means:

• from the barber’s place
• more naturally in English, from the barber or from the barbershop

Hausa very often uses wurin + person/noun to mean at someone’s place, with someone, or to/from someone’s place, depending on the preposition.

Because Hausa commonly expresses locations connected with people by using wuri/wurin.

So instead of saying something directly equivalent to English from the barber, Hausa often says from the barber’s place:

• daga wurin likita = from the doctor’s place / from the doctor
• a wurin malam = at the teacher’s place / with the teacher
• zuwa wurin aboki = to a friend’s place

In your sentence, daga wurin wanzami is the natural Hausa way to express from the barber / from the barbershop.

Here tukuna means yet.

So:

• bai dawo ba tukuna = he has not returned yet

In negative sentences, tukuna often appears near the end of the clause. That placement is very common and natural.

Without tukuna, the sentence would simply mean:

• Musa bai dawo daga wurin wanzami ba. = Musa has not returned from the barber / Musa did not return from the barber.

With tukuna, the meaning adds the idea that the return is still expected:

• not yet

In English, the best translation is often present perfect:

• Musa has not returned from the barber yet.

But depending on context, English might also use:

• Musa didn’t come back from the barber yet
  although this is less standard in some varieties of English

The Hausa form here is often described as a negative completive/perfective construction. In practice, with tukuna, it usually corresponds naturally to English has not ... yet.

So the most natural learner-friendly understanding is:

• bai dawo ba tukuna = has not come back yet

Because Hausa negation in this pattern wraps around the whole predicate, not just the verb alone.

So the structure is roughly:

• bai
  • verb + other information + ba

In your sentence:

• Musa bai dawo daga wurin wanzami ba tukuna

The negative frame surrounds the verbal idea has not returned from the barber. Then tukuna comes after that.

This is normal Hausa word order. You should think of bai ... ba as one unit, even though the two parts are separated.

Yes—but the exact English translation depends on the preposition used with it.

Wurin itself is about place/location, and another word tells you the direction or relationship:

• a wurin = at
• zuwa wurin = to
• daga wurin = from

So in your sentence:

• daga wurin wanzami = from the barber’s place

That is why wurin should not be translated the same way every time by itself.

Yes, that is a very natural implication.

Literally, the sentence says:

• Musa has not yet returned from the barber’s place

A very natural interpretation in context is:

• Musa is still at the barber’s
• or Musa hasn’t come back from the barber yet

So even though Hausa says it in terms of not returning yet, the real-world meaning can easily be that he is still there.
