Nilikushukuru uliponisindikiza kuelekea benki jana jioni.

It has four parts:

• ni- = I
• -li- = past tense
• -ku- = you as the object
• -shukuru = thank

So Nilikushukuru literally means I thanked you.

A useful extra note: -ku- is singular you. If you were talking to more than one person, the object marker would normally be different.

The whole idea when you accompanied me is packed into one verb form:

• u- = you
• -li- = past tense
• -po- = a time-related relative marker, often translated as when
• -ni- = me
• -sindikiza = accompany / escort / see off

So uliponisindikiza means when you accompanied me or when you escorted me.

This is very normal in Swahili: things that need several words in English are often built into one verb.

In this sentence, -po- connects the verb to a time idea. It often means something like when, at the time that, or the moment that.

Compare:

• ulinisindikiza = you accompanied me
• uliponisindikiza = when you accompanied me

So -po- is what turns the second verb into a time clause.

Yes. You could use a phrase like wakati ulinisindikiza... for when you accompanied me...

But uliponisindikiza is compact and very natural Swahili. Learners often expect a separate word because English uses one, but Swahili very often builds that meaning into the verb instead.

Kusindikiza usually means to accompany, to escort, or sometimes to see someone off.

It is a little more specific than just going with someone. It often suggests that one person is accompanying another person for support, courtesy, guidance, or safety.

So here it is not just you were also going; it suggests you accompanied me on the way.

Kuelekea means to head toward, to go in the direction of, or to move toward.

So:

• kwenda benki = to go to the bank
• kuelekea benki = to head toward the bank / toward the bank

In many contexts, English might still translate both simply as to the bank, but kuelekea can sound slightly less focused on actually arriving and more focused on the direction of movement.

Not necessarily.

Because kuelekea means toward or in the direction of, it does not always strongly emphasize arrival. It describes the movement or heading.

If the speaker wanted to emphasize arriving at the bank, a different wording might be clearer, depending on context.

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

So benki can mean:

• a bank
• the bank

The exact meaning comes from context, not from a separate article.

Jana jioni means yesterday evening.

Swahili often uses time expressions directly, without a preposition:

• jana = yesterday
• jioni = evening

So you do not need something like in or on before it.

Putting time expressions at the end is very common and natural in Swahili.

So this order works well:

• Nilikushukuru uliponisindikiza kuelekea benki jana jioni.

But Swahili word order is often flexible enough that time expressions can sometimes appear elsewhere for emphasis. The version here is just a normal, neutral ordering.

Yes.

It has:

1. a main clause: Nilikushukuru = I thanked you
2. a time clause: uliponisindikiza kuelekea benki jana jioni = when you accompanied me toward the bank yesterday evening

So the sentence structure is basically:

I thanked you + when you accompanied me toward the bank yesterday evening

That is one of the most important features of Swahili grammar.

Swahili verbs regularly include:

• the subject
• tense
• sometimes a relative marker
• the object
• the verb root

So instead of using many separate words, Swahili often builds the whole relationship into the verb itself.

That is why forms like Nilikushukuru and uliponisindikiza look long at first, but they are actually very systematic once you learn the pieces.
