Mzabuni amewasilisha nyaraka za zabuni na mahitaji ya kiufundi.

It can be broken down as:

• a- = the subject marker for a singular human noun in noun class 1
• -me- = a perfect marker, often giving the sense of has or a completed action
• wasilisha = submit, present, or deliver

So amewasilisha means something like has submitted or submitted, depending on context.

Because mzabuni is a singular human noun, and Swahili verbs agree with the noun class of the subject.

• mzabuni = singular bidder/tenderer
• singular human subject marker = a-

So:

• Mzabuni amewasilisha = The bidder has submitted
• Wazabuni wamewasilisha = The bidders have submitted

The plural subject marker would be wa-.

No. Mzabuni is grammatically singular human, but it is not inherently male.

It can refer to:

• a man
• a woman
• a company representative, depending on context

Swahili noun class agreement here is about grammar, not biological gender.

They are related, but they mean different things:

• zabuni = tender, bid, or procurement bid
• mzabuni = bidder or tenderer

So mzabuni is the person or entity making the bid, while zabuni is the bid/tender itself.

The za is a connector meaning of and it agrees with nyaraka.

• nyaraka = documents
• za = of, agreeing with the noun class of nyaraka
• zabuni = tender/bid

So nyaraka za zabuni literally means documents of the tender, which in natural English is tender documents or bid documents.

Because the connector must agree with mahitaji, not with kiufundi.

• mahitaji = requirements
• nouns in this class take ya as the of connector

So:

• mahitaji ya kiufundi = technical requirements

Here kiufundi expresses the idea of something being technical or of a technical nature. The important point is that ya agrees with mahitaji.

The singular is hitaji.

• hitaji = requirement / need
• mahitaji = requirements / needs

In this sentence, the plural is used because it refers to more than one requirement.

It can mean either, depending on context.

The -me- marker usually shows a completed action with present relevance, so has submitted is often a very good translation. But in many English contexts, submitted may sound more natural.

So both can be correct:

• The bidder has submitted the tender documents...
• The bidder submitted the tender documents...

Context decides which is best.

Because Swahili does not normally use articles like English does.

English needs words like:

• a bidder
• the bidder
• the documents

Swahili often leaves this to context. So mzabuni can mean:

• a bidder
• the bidder

depending on the situation.

Yes. This is a very normal Swahili sentence pattern:

• Subject: Mzabuni
• Verb: amewasilisha
• Object(s): nyaraka za zabuni na mahitaji ya kiufundi

So it follows a straightforward Subject–Verb–Object order, much like English.

Here na means and.

So it joins two things that were submitted:

• nyaraka za zabuni = tender documents
• mahitaji ya kiufundi = technical requirements

In other contexts, na can also mean with, so learners often need to rely on context.

In this sentence, nyaraka is plural: documents.

A related singular form is waraka, meaning something like document, paper, or letter, though in actual usage nyaraka is very common as a collective word for documents/paperwork.

That is why the agreement is plural:

• nyaraka za zabuni = tender documents

Kiufundi means technical or of a technical nature.

It comes from the idea of ufundi, which relates to craft, skill, or technical know-how. In phrases like mahitaji ya kiufundi, it works very naturally to express technical requirements.

So even though English uses a simple adjective, Swahili often expresses the same idea through a structure like:

• noun + ya/za/etc. + kiufundi

which literally feels like requirements of a technical nature.

You would change both the noun and the subject agreement on the verb:

• Mzabuni amewasilisha... = The bidder has submitted...
• Wazabuni wamewasilisha... = The bidders have submitted...

Notice the two changes:

• mzabuni → wazabuni
• a- → wa-

That is a very common Swahili agreement pattern for human nouns.
