Uwezo wa kubeba ni mkubwa.

Uwezo means ability, capacity, or capability.

It is singular. In Swahili, uwezo belongs to the u-/n- noun class, and that affects how other words connect to it.

Its plural is usually uwezo as well in many practical contexts, though often the idea is treated as an uncountable noun, like capacity or ability in English.

Wa kubeba means of carrying or for carrying.

Here is the breakdown:

• wa = a connector meaning of
• kubeba = to carry

So:

• uwezo wa kubeba = capacity to carry
• literally: ability of carrying

This is a very common Swahili pattern:

• jambo la kusema = a thing to say
• uwezo wa kufanya kazi = ability to work
• nafasi ya kusoma = chance to study

The connector changes to match the noun that comes before it.

Since uwezo belongs to the u-/n- class, its genitive connector is wa.

So:

• uwezo wa kubeba = correct

Other nouns take different connectors:

• kitabu cha mwanafunzi = the student's book
• gari la baba = father's car
• nyumba ya mwalimu = the teacher's house

So wa is not chosen because of kubeba; it is chosen because of uwezo.

In Swahili, adjectives often agree with the noun class of the noun they describe.

Since uwezo is in the u-/n- class, the adjective takes the matching form:

• mkubwa = big, great, large

So:

• uwezo ni mkubwa = the capacity is great / the ability is great

Compare with other classes:

• kitabu kikubwa = a big book
• gari kubwa = a big car
• mtoto mkubwa = a big/older child
• uwezo mkubwa = great ability

The m- in mkubwa is part of the agreement pattern.

Ni is the copula, similar to is/are in English.

So:

• Uwezo wa kubeba ni mkubwa.
• The carrying capacity is great.

Without ni, the sentence would not sound like a normal complete statement in standard Swahili.

You can think of it like this:

• X ni Y = X is Y

Examples:

• Huyu ni mwalimu. = This person is a teacher.
• Nyumba ni kubwa. = The house is big.
• Uwezo wa kubeba ni mkubwa. = The carrying capacity is high/great.

Yes, but specifically it is an infinitive.

• kubeba = to carry

In this sentence, it behaves more like a verbal noun or an action word used after wa:

• uwezo wa kubeba = ability to carry

This is very common in Swahili. Infinitives with ku- are often used after nouns and connectors:

• njia ya kwenda = way to go / route for going
• muda wa kusubiri = time for waiting
• uwezo wa kuelewa = ability to understand

Yes. Depending on context, uwezo wa kubeba can be translated in several natural ways in English, such as:

• carrying capacity
• load capacity
• capacity to carry
• ability to carry

And mkubwa can be translated as:

• great
• large
• high

So in practical English, all of these could fit:

• The carrying capacity is great.
• The load capacity is high.
• It has a high carrying capacity.

The best translation depends on whether the context is technical, everyday, human, or mechanical.

Yes. -kubwa often means more than just big in a physical sense.

Depending on context, it can mean:

• great
• large
• important
• serious
• high

In this sentence, mkubwa does not mean physically big in a literal shape sense. It means the capacity is high/large/great.

So this is a more natural understanding:

• uwezo wa kubeba ni mkubwa = the carrying capacity is high

Yes. That would also be correct, but it is structured a little differently.

• uwezo mkubwa wa kubeba = great capacity to carry
• uwezo wa kubeba ni mkubwa = the capacity to carry is great

The first is a noun phrase. The second is a full sentence.

Compare:

• Ana uwezo mkubwa wa kubeba mizigo. = He/she has great ability to carry loads.
• Uwezo wa kubeba ni mkubwa. = The carrying capacity is great.

Yes, it is very normal.

The structure is:

• [noun phrase] + ni + [adjective]

So:

• Uwezo wa kubeba = subject
• ni = is
• mkubwa = great/high

This is a standard and natural Swahili sentence pattern.

A simple pronunciation guide is:

• Uwezo ≈ oo-weh-zoh
• wa ≈ wah
• kubeba ≈ koo-beh-bah
• ni ≈ nee
• mkubwa ≈ m-koo-bwah

A few useful notes:

• Swahili vowels are usually very consistent:
  • a as in father
  • e as in bet but clearer
  • i as in machine
  • o as in go but pure
  • u as in rule
• mkuu...-type clusters may feel unusual for English speakers, so mkubwa may take practice.
• Stress is usually on the second-to-last syllable:
  • u-WE-zo
  • ku-BE-ba
  • m-KU-bwa

Yes, depending on context.

For a person, it could mean:

• someone has a great ability to carry things

For an object, vehicle, machine, or structure, it could mean:

• it has a high carrying capacity
• it can carry a lot of weight

So the sentence is flexible. The surrounding context tells you whether it is about human strength, storage capacity, engineering, transport, or something similar.
