Tukifika nyumbani, tutamngoja mama.

Tukifika can be broken down as:

• tu- = we
• -ki- = a marker often used for when, if, or upon
• -fika = arrive

So tukifika literally means something like when we arrive or if we arrive, depending on context.

It can mean either if we arrive or when we arrive, because -ki- often covers both ideas.

In a sentence like Tukifika nyumbani, tutamngoja mama, the most natural sense is usually when we arrive home, we will wait for mother/mum.

If the situation is uncertain, it could also be understood as if we arrive home. Context decides which meaning is intended.

Nyumbani is a locative form meaning at home, home, or to/at the house, depending on context.

Swahili often does not need a separate preposition where English does. So:

• nyumbani = home / at home
• tukifika nyumbani = when we arrive home

This is very natural in Swahili.

Tutamngoja can be divided like this:

• tu- = we
• -ta- = future marker, will
• -m- = object marker for him/her
• -ngoja = verb stem from kungoja, to wait for

So tutamngoja means we will wait for him/her.

Since mama comes after it, the full meaning is we will wait for mother/mum.

This is very normal in Swahili.

When the object is a specific person, especially an animate and definite one, Swahili often includes an object marker in the verb even if the noun is also said separately.

So:

• tutamngoja mama = literally something like we will-wait-for-her mother
• Natural English: we will wait for mother/mum

The -m- agrees with mama as a person.

In standard Swahili, with a specific human object like mama, the object marker is usually expected. So tutamngoja mama is the better and more natural form.

You may sometimes hear variation in casual speech, but for learners, it is best to use the object marker with definite human objects.

The dictionary form is kungoja, meaning to wait for.

In the sentence, that verb is expanded with subject, tense, and object markers:

• ku-ngoja = to wait for
• tu-ta-m-ngoja = we will wait for him/her

So the core verb is -ngoja.

Swahili verbs often pack a lot of information into one word. A single verb can include:

• the subject
• the tense
• the object
• the verb meaning itself

So tutamngoja contains all of this:

• we
• will
• her/him
• wait for

This is one of the most important patterns in Swahili grammar.

Swahili does not use articles like the or a.

Also, kinship terms such as mama, baba, dada, and kaka are often used by themselves when the person is clear from context.

So mama can naturally mean:

• mum
• mother
• sometimes the mother, depending on context

If you want to be more specific, you can say things like:

• mama yangu = my mother
• mama yetu = our mother

Yes, that is possible, and it would still be understandable.

However, Tukifika nyumbani, tutamngoja mama is a very natural way to put the time/condition first: When we get home, we’ll wait for mum.

Starting with tukifika nyumbani gives the sentence a clear when that happens, then... structure.

No. -ki- is not a future marker by itself.

It usually introduces a clause meaning if, when, whenever, or while, depending on context. The future in this sentence appears in the second verb:

• tukifika = when/if we arrive
• tutamngoja = we will wait for her

So the real future marker here is -ta- in tutamngoja.

The comma separates the introductory clause from the main clause:

• Tukifika nyumbani = When we arrive home
• tutamngoja mama = we will wait for mother/mum

It works much like English punctuation in a sentence such as When we get home, we’ll wait for Mum.
