Ba za mu fita ba har sai an gyara famfo.

Hausa often uses double negation marking around the verb phrase. In this future sentence:

• Ba
  • za mu fita
    • ba

This is the normal way to say we will not go out or we won’t go out.

So the two bas do not cancel each other out. They work together as one negative frame.

Za is the usual marker for the future in Hausa.

So:

• za mu fita = we will go out
• ba za mu fita ba = we will not go out

A very useful pattern to remember is:

• za + subject pronoun + verb = future
• ba + za + subject pronoun + verb + ba = negative future

In standard Hausa word order, the future marker za comes before the subject pronoun.

So the normal pattern is:

• za ni
• za ka
• za ki
• za mu
• za su

That is why za mu fita means we will go out.

You may sometimes see spellings like zamu in informal writing, but in standard writing it is usually separated as za mu.

Fita basically means go out, come out, or leave, depending on context.

In this sentence, it most naturally means something like:

• go out
• leave

So Ba za mu fita ba can be understood as We won’t go out or We won’t leave.

Har sai usually means until in sentences like this.

So:

• Ba za mu fita ba har sai ... = We won’t go out until ...

It introduces the condition or point that must happen first.

A helpful way to think of it is:

• first, the repair must happen
• only then can mu fita happen

In some contexts har sai can feel close to unless, but here until is the best understanding.

An is a very common Hausa impersonal marker. It often gives a meaning like:

• someone did it
• it was done
• they did it in a general, unspecified way

So an gyara famfo means something like:

• the tap was repaired
• someone repaired the tap
• the tap has been fixed

The person doing the action is not specified. English often uses a passive here, and Hausa often uses an for that kind of idea.

Because the speaker is not interested in saying who did the repair. The important point is only that the repair gets done.

Compare:

• sun gyara famfo = they repaired the tap
  • this tells you there is a specific they
• an gyara famfo = the tap was repaired / someone repaired the tap
  • this leaves the doer unspecified

So an gyara is a very natural choice here.

Gyara is the verb to repair / to fix. In an gyara famfo, it appears in a completed sense: the repair is viewed as something that must be done before the main action happens.

So the idea is not just until they are repairing it, but rather until it has been repaired / fixed.

That completed meaning fits very well after har sai, because the sentence is talking about a point that must be reached before going out.

Famfo usually refers to a tap, faucet, or sometimes a pump, depending on context.

In a sentence about repairing something in the house, tap or faucet is a very natural understanding.

It is also a loanword, ultimately related to English pump, though its meaning in Hausa can shift depending on usage.

Yes. That is a very good natural English translation.

Each part matches well:

• Ba za mu fita ba = We won’t go out / leave
• har sai = until
• an gyara famfo = the tap is fixed / repaired

So We won’t leave until the tap is fixed is a smooth and accurate translation.

Yes. This is a very important pattern.

You can reuse it with many verbs:

• Ba za mu ci ba = We will not eat
• Ba za mu tafi ba = We will not go
• Ba za mu yi aiki ba = We will not work

So the pattern is:

• Ba za mu + verb + ba

If you change the subject pronoun, you can make many other sentences too:

• Ba za ka tafi ba = You will not go
• Ba za su zo ba = They will not come

This sentence is a good model for learning Hausa future negation.
