Tutakaa kwenye kochi tukitazama runinga jioni.

Tutakaa breaks down like this:

• tu- = we
• -ta- = future marker, will
• -kaa = sit / stay / remain

So tutakaa means we will sit or we will stay, depending on context. In this sentence, because of kwenye kochi, the natural sense is we will sit on the couch.

In Swahili, subject markers and tense markers are usually attached directly to the verb stem.

So instead of writing separate words for we + will + sit, Swahili combines them into one verb word:

• tu-
  • -ta-
    • -kaa → tutakaa

The same thing happens in tukitazama.

It can mean both. Kukaa is a broad verb that can mean:

• to sit
• to stay
• to remain
• sometimes even to live/reside, depending on context

In this sentence, since the location is kwenye kochi, the best interpretation is sit.

Kwenye is a very common locative word meaning something like:

• on
• in
• at

The exact English translation depends on the noun that follows.

So:

• kwenye kochi = on the couch

With other nouns, kwenye might be better translated as in or at.

Swahili does not normally use articles like English a, an, or the.

So:

• kochi can mean a couch or the couch
• runinga can mean a television / TV or the television / TV

Context tells you which one is meant. In this sentence, English naturally uses the couch and TV.

Tukitazama can be broken down like this:

• tu- = we
• -ki- = a marker often used for while / when / if
• -tazama = watch / look at

So tukitazama means while we are watching or as we watch.

That is why the sentence has the sense:

• We will sit on the couch while watching TV in the evening.

No. -ki- is flexible. Depending on context, it can mean:

• while
• when
• if

For example, the same structure can express simultaneous action, condition, or time. In this sentence, because the two actions happen together, while is the best translation.

So here:

• tukitazama runinga = while watching TV

Yes, in natural English that is often a perfectly good translation.

But grammatically, tukitazama is a bit more specifically while watching or as we watch, not just a plain and.

So:

• more literal: We will sit on the couch while watching TV in the evening.
• more natural English in many situations: We’ll sit on the couch and watch TV in the evening.

Runinga means television or TV.

It is a standard Swahili word, but in everyday speech many speakers also use televisheni. So both may be heard, depending on region, register, and personal habit.

In this sentence:

• kutazama runinga = to watch TV

Jioni means in the evening / evening.

Time expressions in Swahili are fairly flexible. Putting jioni at the end is very natural, but you could also move it earlier for emphasis.

For example:

• Tutakaa kwenye kochi tukitazama runinga jioni.
• Jioni tutakaa kwenye kochi tukitazama runinga.

Both are natural. The difference is mostly about emphasis and flow, not basic meaning.
