Nitanunua stempu moja kabla ya kutuma barua hii.

Nitanunua can be broken into:

• ni- = I
• -ta- = future tense marker (will)
• -nunua = buy

So nitanunua literally means I will buy.

This is very typical Swahili verb structure:
subject marker + tense marker + verb stem

For example:

• ninasoma = I am reading
• nitasoma = I will read
• nilisoma = I read / I was reading

In Swahili, a full finite verb is usually written as one word because the subject marker, tense marker, and verb stem are all part of the same verb form.

So English I will buy becomes one word in Swahili:

• ni-
  • -ta-
    • -nunua → nitanunua

This is normal in Swahili grammar, not a special case.

In Swahili, numbers usually come after the noun they describe.

So:

• stempu moja = one stamp
• barua mbili = two letters
• vitabu vitatu = three books

This is different from English, where the number usually comes before the noun.

Yes. Stempu means stamp and it is a loanword, ultimately from English.

Swahili contains many borrowed words, adapted to Swahili sound patterns.
Other examples include:

• baiskeli = bicycle
• benki = bank
• meza = table

So stempu moja means one stamp.

Kabla ya kutuma means before sending or before I send in this sentence.

Breakdown:

• kabla = before
• ya = of / linking word used here after kabla
• kutuma = to send / sending

So literally it is something like before of sending, but in natural English we say before sending or before I send.

This is a very common pattern:

• kabla ya kuondoka = before leaving
• kabla ya kula = before eating
• kabla ya kusoma = before reading

The ku- here marks the infinitive form of the verb.

• -tuma = send
• kutuma = to send / sending

After expressions like kabla ya, Swahili often uses this infinitive form.

So:

• kabla ya kutuma = before sending
• baada ya kusoma = after reading
• bila kusema is a little different structurally, but also shows how Swahili often uses verb forms where English might use -ing

Swahili often leaves the subject unstated in non-finite expressions like this when it is clear from context.

In this sentence, the main verb nitanunua already tells us the subject is I, so kabla ya kutuma barua hii is naturally understood as before sending this letter or before I send this letter.

If needed, Swahili can make the subject more explicit in other ways, but here it is not necessary.

Yes. In natural translation, it can often be understood either way depending on context.

Swahili infinitive constructions like kabla ya kutuma do not always specify the subject explicitly, so English may translate them in more than one natural way:

• before sending this letter
• before I send this letter

Both fit this sentence well.

In Swahili, demonstratives such as this usually come after the noun.

So:

• barua hii = this letter
• kitabu hiki = this book
• watu hawa = these people

This is the normal order in Swahili.

Because barua belongs to a noun class that takes the demonstrative hii for this.

Swahili nouns are grouped into classes, and words that go with them often have to agree with that class.

For example:

• barua hii = this letter
• nyumba hii = this house

But with other noun classes, the form changes:

• kitabu hiki = this book
• mtu huyu = this person
• watu hawa = these people

So hii is used because it matches the noun class of barua.

Swahili does not have articles like English a, an, and the.

That means nouns often appear without any separate article word:

• stempu moja = one stamp
• barua hii = this letter

Definiteness is usually understood from context or shown in other ways, such as with a demonstrative like hii (this).

So Swahili does not need a separate word for a or the here.

Yes, very typical.

The sentence follows a common pattern:

Verb + object + time-related phrase + another object phrase

Breakdown:

• Nitanunua = I will buy
• stempu moja = one stamp
• kabla ya kutuma = before sending
• barua hii = this letter

So the overall structure is very natural Swahili.

Yes. You could say:

• Nitanunua stempu kabla ya kutuma barua hii.

That would mean I will buy a stamp before sending this letter.

Adding moja emphasizes the number one:

• stempu = a stamp / stamp
• stempu moja = one stamp

So moja is used when you want to specify the quantity clearly.

A rough pronunciation guide is:

Nee-tah-noo-NOO-ah STEM-poo MO-jah KAH-blah yah koo-TOO-mah bah-ROO-ah HEE-ee

A few tips:

• Swahili vowels are usually pronounced clearly:
  • a as in father
  • e as in bed (but often a bit purer)
  • i as in machine
  • o as in go (without a heavy glide)
  • u as in rule
• Stress is usually on the second-to-last syllable:
  • nitaNUnua
  • STEMpu
  • MOja
  • kuTUma
  • baRUa

Yes, absolutely. It is a very useful pattern:

Nita- + verb + object + kabla ya ku- + verb + object

Examples:

• Nitasoma kitabu hiki kabla ya kulala.
  I will read this book before sleeping.

• Nitapika chakula kabla ya kuondoka.
  I will cook food before leaving.

• Nitaandika ujumbe kabla ya kwenda.
  I will write a message before going.

So this sentence is a great model for learning future tense and kabla ya + infinitive structures.
