Tutakutana kituoni mara tu gari moshi litakapowasili.

tutakutana breaks down into:

• tu- (1st person plural subject “we”)
• -ta- (future tense marker “will”)
• kutana (verb root “meet”)

So literally tu-ta-kutana = “we will meet.”

• kituo means “station” or “stop.”
• The suffix -ni is the locative marker meaning “at” or “in.”

Thus, kituoni = “at the station.”

mara means “time” or “once,” and tu adds the sense of “just” or “only.” Together mara tu = “as soon as” or “just when.” It indicates that the meeting happens immediately after the train’s arrival.

• gari = “vehicle, carriage”
• moshi = “steam”

Historically gari moshi meant “steam carriage,” hence “train.” Today many Swahili speakers also use the loanword treni, so you could equally say treni instead of gari moshi.

litakapowasili = li- + ‑ta- + ‑ka- + ‑po- + wasili

• li- = subject concord for class 5 noun gari (“it”)
• -ta- = future tense marker (“will”)
• -ka- = relative‐clause marker (“when”)
• -po- = locative/time focus in the relative clause
• wasili = verb root “arrive”

Altogether it means “when it will arrive” or “once it arrives.”

Swahili commonly pairs -ta-…-po- to form a time clause meaning “as soon as.” You could use a present‐relative also: inapofika (“when it arrives”) but ta-…-po- emphasizes that both events are future and occur in quick succession (“as soon as it will arrive, we will meet”).

Yes. For example:

• Tutakutana kituo cha treni mara itakapofika.
• Mara tu gari moshi litakapowasili, tutakutana kituoni.
• Tutakutana kituoni inapofika treni.

All these preserve “We will meet at the station as soon as the train arrives.”
