Katika taifa letu, kila mgombea anapaswa kueleza sera zake waziwazi.

Katika means in, within, or inside in a fairly neutral or formal way.

In this sentence, Katika taifa letu means In our nation.

A few comparisons:

• katika = in/within; often common in written or formal Swahili
• kwenye = on/in/at; often used with locations in everyday speech
• ndani ya = inside of, in the interior of

So Katika taifa letu sounds natural and somewhat formal, which fits a sentence about candidates and policies.

In Swahili, possessives usually come after the noun, not before it.

So:

• taifa letu = our nation
• literally: nation our

This is the normal pattern in Swahili:

• kitabu changu = my book
• rafiki yetu = our friend
• sera zake = his/her policies

English puts the possessive first; Swahili usually puts it second.

Swahili possessives must agree with the noun class of the thing being possessed.

Taifa belongs to noun class 5 in the singular. For that class, our becomes letu.

So:

• taifa letu = our nation

The important idea is that the possessive agrees with taifa, not with the people who own it.

Kila means each or every.

After kila, Swahili normally uses a singular noun:

• kila mgombea = every candidate

Even though the meaning refers to many people one by one, the noun stays singular. This is similar to English every candidate, not every candidates.

So kila mgombea is correct, while kila wagombea would be wrong.

The plural of mgombea is wagombea.

• mgombea = candidate
• wagombea = candidates

But because the sentence uses kila (every/each), Swahili uses the singular:

• kila mgombea = every candidate

If you wanted to say the candidates, then wagombea could be used.

Anapaswa means something like he/she should, he/she is supposed to, or he/she is required to, depending on context.

It can be broken down like this:

• a- = he/she subject marker for a person in singular
• -na- = present tense marker
• -paswa = be obliged / be expected / be supposed to

So anapaswa literally gives the idea he/she is supposed to or he/she should.

Because mgombea is singular, the verb also uses the singular person marker a-.

Because Swahili usually puts the subject information inside the verb.

In anapaswa, the a- already means he/she.

So Swahili often does not need a separate subject pronoun unless you want emphasis.

For example:

• anapaswa = he/she should
• wanapaswa = they should

This is very different from English, where you normally need an independent subject like he, she, or they.

The ku- form is the infinitive, like English to explain.

So:

• kueleza = to explain / to state

After a verb like anapaswa (should / is supposed to), Swahili normally uses the infinitive:

• anapaswa kueleza = he/she should explain

This is similar to English should explain, though Swahili expresses it with the infinitive form.

This is a very common question.

In Swahili, possessives agree with the thing possessed, not with the possessor.

Here, the possessed noun is sera (policies). For this noun class, the possessive pattern is za-.

So:

• zake = his/her ... for this noun class
• sera zake = his/her policies

Even though the owner is one person, you still use zake, because it must agree with sera, not with mgombea.

That is one of the biggest differences from English.

Wazi means clear, open, or plain.

When it is repeated as waziwazi, it becomes an adverb-like form meaning:

• clearly
• openly
• plainly

Reduplication like this is common in Swahili and often adds emphasis or gives a more adverbial sense.

So kueleza sera zake waziwazi means to explain or state one’s policies clearly/openly.

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

So a noun like mgombea can mean:

• a candidate
• the candidate
• candidate

The exact meaning depends on context.

In this sentence, the meaning is understood from the whole expression:

• kila mgombea = every candidate

So Swahili does not need a separate word for the.

Yes. Swahili word order is somewhat flexible, especially for location or context phrases.

This sentence begins with Katika taifa letu to set the scene: In our nation...

You could also place that phrase later, though the original order sounds natural and formal:

• Kila mgombea anapaswa kueleza sera zake waziwazi katika taifa letu.

That said, the original version is good because it foregrounds the national context first.

It sounds fairly formal and somewhat political/civic in tone.

Words like these contribute to that feeling:

• taifa = nation
• mgombea = candidate
• sera = policies
• waziwazi = openly/clearly

So this sounds like something you might read in a civics text, news article, speech, or discussion about elections rather than very casual conversation.
