Kapteni anamsaidia mwenzake wakati wa mechi.

It has four main parts:

• a- = he/she
• -na- = present tense
• -m- = him/her
• -saidia = help

So anamsaidia means he/she helps him/her or he/she is helping him/her.

That -m- is the object marker, and Swahili often uses it when the object is a specific person.

So in Kapteni anamsaidia mwenzake, the verb already tells you the captain is helping him/her, and then mwenzake names who that person is. This is very normal in Swahili, especially with human objects.

No. Swahili does not normally mark gender the way English does.

In this sentence:

• a- can mean he or she
• -m- can mean him or her
• mwenzake also does not show male vs. female

So the exact gender comes from context, not from the grammar itself.

Mwenzake means something like his/her companion, colleague, counterpart, fellow, or teammate, depending on context.

In a sports sentence like this one, learners often understand it as his/her teammate or fellow player. It is a relationship word, not necessarily a close friend.

Here, wakati means time or period, and wa is a linking word meaning roughly of.

So wakati wa mechi is literally the time of the match, which naturally means during the match.

This X wa Y pattern is very common in Swahili.

Even though kapteni does not have an obvious class prefix like some other nouns, it refers to a person, so it takes the normal singular human agreement on the verb.

That is why you get:

• Kapteni anamsaidia... = The captain helps/is helping...

The important point is that human nouns usually trigger the person agreement pattern.

-na- is the present tense marker.

Depending on context, it can mean either:

• helps
• is helping

So this sentence can describe something habitual or something happening now. Context tells you which is intended.

Yes. The basic order here is:

• Kapteni = subject
• anamsaidia = verb
• mwenzake = object
• wakati wa mechi = time phrase

But the time phrase can move for emphasis. For example:

• Wakati wa mechi, kapteni anamsaidia mwenzake.

That still means the same thing, just with more focus on during the match.

Yes. Kusaidia is the standard verb meaning to help or to assist.

In this sentence, the dictionary form kusaidia changes into anamsaidia because Swahili verbs add prefixes for the subject, tense, and object. So the core meaning stays help, but the full verb form packs in a lot of grammar.
