Mshtakiwa amekiri kosa.

Mshtakiwa means the accused person, the defendant, or the one being charged, depending on context.

It is a noun referring to a person, and it belongs to the m-/wa- noun class for people:

• singular: mshtakiwa
• plural: washtakiwa

So if you wanted the defendants, you would say washtakiwa.

It comes from the verb -shtaki, meaning to accuse or to charge.

Amekiri can be broken down like this:

• a- = subject marker for he/she or a singular person noun such as mshtakiwa
• -me- = perfect marker, often giving the sense of has/have
• -kiri = verb root meaning admit or confess

So:

• a-me-kiri = he/she has admitted

Because mshtakiwa is a singular person noun, the verb takes a-.

In Swahili, ideas like has, had, is, or will are often built into the verb itself rather than expressed as separate words.

So in amekiri, the -me- part carries the idea of has:

• amekiri = has admitted

This is very different from English, where auxiliary verbs like has are separate words.

The difference is mainly tense/aspect:

• amekiri = has admitted / has confessed
• alikiri = admitted / confessed

The -me- form often connects the action to the present in some way, like the English present perfect. The -li- form is a more straightforward past tense.

So:

• Mshtakiwa amekiri kosa. = The defendant has admitted the offense.
• Mshtakiwa alikiri kosa. = The defendant admitted the offense.

Kosa literally means fault, mistake, wrong, or offense.

In legal contexts, it can mean things like:

• offense
• charge
• crime
• guilt/fault

So in this sentence, kosa is best understood from context. Depending on the translation style, it might be rendered as:

• the offense
• the charge
• the wrongdoing
• guilt

That is why this sentence can feel slightly broader than a single fixed English translation.

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

That means a noun like mshtakiwa can mean:

• a defendant
• the defendant

and kosa can mean:

• a fault
• the offense
• an error

You figure out the exact meaning from context.

The word order is:

Subject + Verb + Object

So:

• Mshtakiwa = subject
• amekiri = verb
• kosa = object

This is the same basic order as in English:

• The defendant has admitted the offense.

So in that sense, the sentence structure is fairly familiar to an English speaker.

The a- is the subject marker used for:

• he
• she
• singular human nouns in the same agreement class

Since mshtakiwa is a singular person, the verb must agree with it:

• Mshtakiwa amekiri = The defendant has admitted

If the subject were plural, the verb would change:

• Washtakiwa wamekiri kosa. = The defendants have admitted the offense.

Here:

• wa- = subject marker for plural people
• -me- = perfect marker
• -kiri = admit

It is passive in form.

Mshtakiwa literally has the sense of the one who is accused/charged. That is why it refers to the defendant or accused person, rather than the accuser.

This is a common pattern in Swahili, where a noun can be formed from a verb and include a passive meaning.

So from -shtaki = accuse, you get mshtakiwa = the accused person.

Yes, very possibly.

Because kosa can cover a range of meanings such as fault, wrongdoing, offense, or guilt, the phrase can sometimes be understood more idiomatically as:

• has admitted guilt
• has confessed to the offense
• has admitted the charge

The best English translation depends on the legal or conversational context.

You would change the subject noun and the subject marker on the verb:

• singular: Mshtakiwa amekiri kosa.
• plural: Washtakiwa wamekiri kosa.

Breakdown of the plural verb:

• wa- = they / plural people
• -me- = have
• -kiri = admit

So wamekiri means they have admitted.

You can say:

Mshtakiwa hajakiri kosa.

Breakdown:

• ha- = negative subject marker for singular third person
• -ja- = negative perfect
• -kiri = admit

So:

• amekiri = has admitted
• hajakiri = has not admitted

This is a useful contrast to learn early.

A simple pronunciation guide is:

msh-ta-KI-wa a-me-KI-ri KO-sa

A few notes:

• sh sounds like the sh in ship
• vowels are usually pure and clear:
  • a like a in father
  • e like e in bed but often cleaner
  • i like ee in see
  • o like o in told, but without a strong glide
• stress in Swahili is usually on the second-to-last syllable, so:
  • msh-ta-KI-wa
  • a-me-KI-ri
  • KO-sa

Yes, it sounds fairly formal and especially natural in a legal context.

Words like mshtakiwa and kosa are common in court, police, or official discussions. In everyday conversation, people might choose different wording depending on what exactly they mean.

So this is a good sentence for learning grammar, but it also clearly belongs to a more formal register than casual daily speech.
