Wananchi wanasikiliza mdahalo wa wagombea kwenye redio jioni.

Wanasikiliza can be broken down like this:

• wa- = they
• -na- = present tense marker
• sikiliza = listen

So wa-na-sikiliza literally gives the idea they are listening / they listen.

A useful thing to notice is that Swahili does not need a separate word for are here. The present meaning is already built into the verb through -na-.

The wa- at the beginning of wanasikiliza agrees with wananchi, which is a plural noun referring to people.

• mwananchi = citizen
• wananchi = citizens

Because the subject is plural and human, the verb uses the subject prefix wa-. This kind of agreement is a major feature of Swahili grammar.

Wananchi is the plural of mwananchi. It belongs to the common human noun pattern:

• singular: m- / mw-
• plural: wa-

So:

• mwananchi = one citizen
• wananchi = citizens

English speakers often need to get used to the fact that Swahili nouns belong to noun classes, and those classes affect agreement in other parts of the sentence.

In Swahili, kusikiliza usually takes a direct object. So you say:

• wanasikiliza mdahalo = they are listening to a/the debate

You do not need a separate word corresponding to English to here.

This is a common difference between English and Swahili:

• English: listen to the radio
• Swahili: sikiliza redio

This is a very common question.

• kusikiliza = to listen
  This suggests attention or intention.
• kusikia = to hear
  This is more about perceiving sound.

So in this sentence, wanasikiliza is correct because the citizens are actively listening to the debate.

Compare:

• Ninasikiliza redio = I am listening to the radio
• Nasikia sauti = I hear a sound/voice

Mdahalo wa wagombea means something like the candidates' debate or a debate of the candidates.

That middle wa is a linking word often called the associative marker. It often corresponds to English of or the possessive idea in candidates'.

So:

• mdahalo = debate
• wa = of
• wagombea = candidates

Together: debate of candidates → more naturally in English, candidates' debate

The form wa is chosen because it agrees with mdahalo.

Wagombea means candidates. The singular is mgombea.

So:

• mgombea = candidate
• wagombea = candidates

This is another example of the human noun pattern:

• singular m-
• plural wa-

In many contexts, mgombea / wagombea especially refers to political or election candidates.

Yes, kwenye redio here means on the radio or via the radio.

Kwenye is a locative word that can mean in, on, or at, depending on context. With something like redio, it is understood idiomatically as on the radio, not physically on top of a radio.

So this phrase means the debate is being heard through radio broadcasting.

Yes, very often you can hear redioni, and it is natural.

• kwenye redio = on the radio
• redioni = on the radio / at the radio

Both can work, though style and regional preference may vary. A learner should recognize both.

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

So a noun like mdahalo can mean:

• a debate
• the debate

The exact meaning depends on context.

If Swahili wants to be more specific, it can use other words such as demonstratives, context, or descriptive phrases. But very often no article is needed at all.

Jioni means in the evening or evening. In this sentence, it tells you when the action happens.

A useful thing to notice is that Swahili often uses time words without a preposition like in:

• jioni = in the evening
• asubuhi = in the morning
• usiku = at night

So jioni works as a time expression on its own.

Yes. Swahili word order is somewhat flexible, especially with time expressions.

The given sentence is neutral and natural:

• Wananchi wanasikiliza mdahalo wa wagombea kwenye redio jioni.

But you could also say:

• Jioni, wananchi wanasikiliza mdahalo wa wagombea kwenye redio.

That puts more focus on when it happens. The basic meaning stays the same.

Yes. It follows a very normal pattern:

• Wananchi = subject
• wanasikiliza = verb
• mdahalo wa wagombea = object
• kwenye redio = place/medium phrase
• jioni = time phrase

So the sentence is built in a straightforward, natural way. For an English speaker, the main differences are not the overall order, but things like noun-class agreement, the lack of articles, and the fact that kusikiliza takes a direct object.
