Japo kifurushi kilichopotea kimepatikana, ada ya usafirishaji haijarejeshwa.

Japo means although, even though, or though. It introduces a contrast:

• Japo kifurushi kilichopotea kimepatikana = Although the lost package has been found

It is a concessive word: one thing is true, but another unexpected thing is also true.

A close synonym is ingawa. In many contexts, you could replace japo with ingawa without much change in meaning.

Because kifurushi belongs to noun class 7, and class 7 nouns usually trigger ki- agreement.

So:

• kifurushi = package
• class 7 agreement = ki-

That agreement shows up on words linked to the noun:

• ki-li-cho-potea
• ki-me-patikana

If the noun were plural, vifurushi, the agreement would usually change to vi-.

Kilichopotea can be broken down like this:

• ki- = class 7 agreement, matching kifurushi
• -li- = past tense
• -cho- = relative marker for class 7, meaning something like which/that
• -potea = be lost, get lost

So kilichopotea literally means something like:

• that which got lost
• more naturally: which was lost or that got lost

So kifurushi kilichopotea = the package that was lost.

Not exactly. It functions like an adjective in English, but grammatically it is better understood as a relative verb form or a relative clause built into one word.

English often uses:

• the lost package
• the package that was lost

Swahili commonly uses the second type of idea inside one verb form:

• kifurushi kilichopotea

So it behaves like a description of the noun, but it is verbal in structure.

Because kimepatikana means it has been found or it has turned up, while kimepata would mean it has gotten/obtained something, which is a different idea.

Breakdown of kimepatikana:

• ki- = class 7 subject, matching kifurushi
• -me- = perfect aspect, often has/have
• -patikana = be found, be available, turn up

So:

• kimepatikana = it has been found

This is the natural form when the package is the thing that was found.

Haijarejeshwa breaks down like this:

• ha- = negative
• -i- = subject marker for class 9, matching ada
• -ja- = negative perfect
• -rejesh- = return, restore, refund
• -w- = passive
• -a = final vowel

So haijarejeshwa means:

• it has not been returned
• in this context, it has not been refunded

A useful comparison:

• imerejeshwa = it has been returned/refunded
• haijarejeshwa = it has not been returned/refunded

Because ada belongs to noun class 9. In Swahili, agreement is based on noun class, not on whether something is physically a person or object.

That is why you get:

• ada ya usafirishaji
• ada ... haijarejeshwa

Here the class 9 agreement shows up as:

• ya in ada ya usafirishaji
• i- inside haijarejeshwa

This is something learners often just have to memorize with the noun.

Ya is the connector meaning of, and it agrees with ada, the first noun.

So:

• ada ya usafirishaji = fee of shipping
• natural English: shipping fee

This -a connector changes form depending on noun class:

• kitabu cha mwanafunzi = student’s book / book of the student
• mlango wa nyumba = door of the house
• ada ya usafirishaji = shipping fee

Here it is ya because ada is class 9.

Usafirishaji means shipping, transport, or shipment as a process or service.

It comes from the verb kusafirisha, which means to transport or to ship.

A simple way to see it is:

• safirisha = transport, ship
• usafirishaji = transportation, shipping

The noun refers to the activity or service itself, so ada ya usafirishaji is the fee charged for that service.

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

So a noun like kifurushi can mean:

• a package
• the package

The exact meaning comes from context.

In this sentence, the context makes it clear that we mean a specific package and a specific fee, so English naturally uses the:

• the lost package
• the shipping fee

Because the sentence is talking about two different events with two different time perspectives:

• kilichopotea = the package that got lost earlier
• kimepatikana = it has been found now, with a present result

So the loss is treated as an earlier event, while the finding is presented as something relevant to the present moment.

That contrast is very natural in Swahili:

• earlier event: -li-
• present-result meaning: -me-

Yes. You could also say:

• Ada ya usafirishaji haijarejeshwa, japo kifurushi kilichopotea kimepatikana.

The meaning stays very similar.

The original order puts the although part first, which sets up the contrast immediately:

• package found ... but fee still not refunded

That word order is very natural and common in both Swahili and English.
