Lango la mbele likifungwa, mbwa wetu hukaa tulivu ndani ya ua.

Because lango belongs to noun class 5, and the connector -a has to agree with that noun class.

So:

• lango = gate
• la = class-5 form of the connector -a
• mbele = front / in front

So lango la mbele literally means gate of the front, which is the normal way to say front gate.

Mbele literally means front, ahead, or in front.

In lango la mbele, it works like front in English, so the phrase means the front gate.

You will often see mbele in other expressions too, such as:

• mbele ya nyumba = in front of the house
• nenda mbele = go ahead / go forward

Likifungwa can be broken down like this:

• li- = subject marker agreeing with lango (class 5)
• -ki- = if / when
• fung- = root from kufunga = to close
• -w- = passive
• -a = final vowel

So likifungwa means something like if/when it is closed.

Because it agrees with lango, the verb starts with li-.

It can mean either, depending on context.

In Swahili, -ki- often introduces a condition or a repeated circumstance:

• if
• when
• whenever

In this sentence, because the main verb is hukaa (habitual), the overall sense is often when/whenever the front gate is closed rather than just a one-time if.

Because the gate is the thing receiving the action.

The sentence is about the gate being closed, not about someone closing the gate.

So Swahili uses the passive:

• kufunga = to close
• kufungwa = to be closed

If you wanted to say when someone closes the front gate, you would need an active verb with a subject, for example a structure like mtu akilifunga...

The verb kaa can mean stay, remain, sit, or sometimes live, depending on context.

Here, hukaa means usually stays/remains.

The prefix hu- marks a habitual action, so it gives the idea of:

• usually
• generally
• whenever this happens
• as a habit

So mbwa wetu hukaa tulivu means our dog usually stays calm.

In this habitual form, hu- is doing the tense/aspect job, and the subject is already clearly stated as mbwa wetu.

So Swahili does not need an extra subject prefix inside the verb here.

That is normal in sentences like this:

• watoto husoma = children study / children usually study
• mbwa wetu hukaa tulivu = our dog usually stays calm

Not necessarily.

Although kukaa can sometimes mean to sit, in this sentence it is better understood as to stay or remain.

So hukaa tulivu means:

• stays calm
• remains quiet
• keeps still

It is more about the dog's state or behavior than about the physical position of sitting.

Here tulivu is being used after the verb hukaa as a complement describing the dog's state: calm / quiet.

So the phrase works like:

• hukaa tulivu = stays calm / remains quiet

In this kind of structure, Swahili often uses the descriptive word directly after the verb to describe the resulting state.

Ndani ya means inside of or within.

So:

• ndani = inside, interior
• ya = linker used in this expression
• ua = yard, courtyard, enclosure, compound

So ndani ya ua means inside the yard/enclosure.

A useful pattern to remember is:

• ndani ya nyumba = inside the house
• ndani ya gari = inside the car
• ndani ya ua = inside the yard/enclosure

Here ua means something like yard, courtyard, or enclosed area/compound.

Depending on context, ua can refer to the enclosed outdoor space around a home. In this sentence, that fits well because the dog stays inside the enclosure once the front gate is closed.

It describes a usual pattern.

Two things point to that:

• -ki- in likifungwa can mean when/whenever
• hu- in hukaa marks habitual action

So the sentence is not just about one single moment. It means something like whenever the front gate is closed, our dog stays calm inside the yard.

Swahili often puts a condition or background situation first, just like English can do:

• When the front gate is closed, our dog stays calm...

So the first part sets the scene, and the second part gives the result.

Structure:

• Lango la mbele likifungwa = when/whenever the front gate is closed
• mbwa wetu hukaa tulivu ndani ya ua = our dog usually stays calm inside the yard

This word order is very natural in Swahili.
