Mwalimu alituonyesha jinsi ya kutumia dira wakati wa somo la jiografia.

Because in Swahili, the verb normally carries a subject marker, even when the subject noun is stated separately.

So in Mwalimu alituonyesha:

• Mwalimu = the teacher
• a- = he/she

That is normal Swahili grammar. The noun and the verb agree with each other.

It breaks down as:

• a- = he/she
• -li- = past tense
• -tu- = us
• -onyesha = show

So a-li-tu-onyesha means he/she showed us.

No. Swahili does not mark gender here.

• Mwalimu can refer to a male or female teacher.
• a- means he/she, not specifically one or the other.

You only know the teacher’s gender if the wider context makes it clear.

Literally, it is something like the way of using or the manner of using.

In normal English, that becomes how to use.

So:

• jinsi = way, manner, how
• ya = a linking word here
• kutumia = to use

Together, jinsi ya kutumia dira means how to use a compass.

Here, ya is a linking/associative marker. It connects jinsi to the infinitive phrase kutumia dira.

A useful way to think of it is:

• jinsi ya kutumia dira = the way of using a compass = how to use a compass

Learners often first meet ya as meaning something like of, and that idea helps here, even though the whole phrase is best translated more naturally as how to use.

Because ku- is the infinitive prefix, similar to English to.

So:

• kutumia = to use
• verb stem: -tumia = use

This is the normal dictionary form of a Swahili verb. After jinsi ya, Swahili keeps the infinitive: jinsi ya kutumia = how to use.

Sometimes in natural English, yes, depending on context. But onyesha literally means show or demonstrate.

So this sentence most literally means:

• The teacher showed us how to use a compass

In a classroom setting, English might also say taught us how to use a compass, but the Swahili verb here emphasizes showing/demonstrating.

These are both examples of the Swahili associative marker, often translated loosely as of or used in phrases like during.

The form changes depending on the noun before it.

• wakati wa somo = during the lesson
• somo la jiografia = geography lesson

So:

• wa agrees with wakati
• la agrees with somo

This is part of the noun class system in Swahili. English keeps of the same, but Swahili changes the linker to match the noun class.

It means during the geography lesson or during geography class.

Piece by piece:

• wakati = time
• wa = of
• somo = lesson/class
• la jiografia = of geography

So literally it is close to at the time of the geography lesson, but in natural English we usually say during the geography lesson.

In this sentence, yes, dira most naturally means a compass, the tool used in geography or navigation.

In other contexts, dira can sometimes have a broader or more figurative sense related to direction or guidance, but here the classroom and geography context makes the physical instrument the most likely meaning.

Broadly, yes. The sentence follows a pattern that feels fairly familiar to an English speaker:

• Mwalimu = subject
• alituonyesha = verb
• jinsi ya kutumia dira = what was shown
• wakati wa somo la jiografia = time phrase

So the overall structure is quite close to English: The teacher showed us how to use a compass during the geography lesson.
