Tafadhali punguza sauti ya runinga, bibi anasoma kitabu sebuleni.

Tafadhali means please. It makes the command more polite.

It is not grammatically required, but without it the sentence sounds more direct. In this sentence, it softens punguza sauti ya runinga into a polite request.

It often appears at the beginning of a sentence, but you may also hear it in other positions depending on style.

Kupunguza is the infinitive, meaning to reduce or to lower.

Punguza is the imperative form, used when telling someone to do something:

• kupunguza = to lower
• punguza = lower

So here, punguza is correct because the speaker is giving a request or instruction.

If you were addressing more than one person, or using the plural imperative, you would commonly say punguzeni.

This is a very common Swahili structure:

• sauti = sound, voice
• ya = of
• runinga = television, TV

So literally it is the sound of the television.

In natural English, this often becomes the TV volume or the sound of the TV.

The word ya is part of the possessive or associative pattern in Swahili. It changes depending on the noun class of the first noun. Since sauti belongs to a class that takes ya, you get sauti ya runinga.

In Swahili, words like of must agree with the noun class of the noun that comes before them.

Here the head noun is sauti, so the connector must match sauti, not runinga.

That is why you get:

• sauti ya runinga

If the first noun were from a different noun class, the connector would change. For example:

• kitabu cha mwanafunzi = the student's book
• watoto wa bibi = grandmother's children

So ya is there because of the noun class of sauti.

No. Runinga is a standard Swahili word for television, but many speakers also use televisheni.

Both are understood. Which one you hear more often can depend on region, formality, and personal preference.

So a learner should recognize both:

• runinga
• televisheni

Bibi most often means grandmother, but it can also refer to an elderly woman, or be used respectfully for an older woman depending on context.

So the exact meaning depends on the situation. In this sentence, it most naturally means grandmother.

Anasoma can be broken down like this:

• a- = he or she
• -na- = present tense marker
• -soma = read, study

So anasoma means he/she is reading, he/she reads, or sometimes he/she is studying, depending on context.

Here it means she is reading.

It can mean both.

That is very common in Swahili:

• kusoma kitabu = to read a book
• kusoma shuleni = to study at school

The surrounding words tell you which meaning is intended. Since the sentence includes kitabu meaning book, the meaning here is clearly read.

Because Swahili verbs already include subject and tense information inside the verb itself.

In English, you need is reading.
In Swahili, that idea is packed into anasoma:

• a- = she
• -na- = present or ongoing action
• -soma = read

So there is no need for a separate word like is.

Swahili generally does not use articles like English a, an, and the.

So nouns such as bibi, kitabu, and runinga appear without articles. Whether they mean a book, the book, a grandmother, or the grandmother depends on context.

That is normal in Swahili, and learners have to get used to relying more on context than on articles.

Sebule means living room or sitting room.

When you add -ni, it becomes a location word:

• sebule = living room
• sebuleni = in the living room, at the living room

The ending -ni is a very common locative ending in Swahili. It often gives the idea of in, at, or to, depending on context.

So bibi anasoma kitabu sebuleni means that the reading is happening in the living room.

Yes, it is very natural.

The first part is a polite imperative:

• Tafadhali punguza sauti ya runinga

The second part is a normal statement with subject, verb, object, and location:

• bibi = subject
• anasoma = verb
• kitabu = object
• sebuleni = location

Swahili word order is often similar to English in simple sentences, though it can be more flexible when speakers want to emphasize something.

Yes, they could be separate sentences.

The comma links two closely related ideas:

• lower the TV volume
• grandmother is reading in the living room

The listener is expected to understand the connection: the TV should be quieter because grandmother is reading.

In very careful writing, someone might choose to make the relationship more explicit, or simply write them as two sentences. But as written, the meaning is clear and natural enough.

A few useful pronunciation points:

• Swahili usually pronounces every vowel clearly
• stress is usually on the second-to-last syllable
• dh in tafadhali sounds like the th in this

Approximate syllable breakdowns:

• ta-fa-DHA-li
• pu-NGU-za
• sa-U-ti
• ru-NIN-ga
• a-na-SO-ma
• ki-TA-bu
• se-bu-LE-ni

Two especially useful details:

• sauti has all its vowels pronounced, so do not crush it into one English-style syllable
• runinga has a hard ng sound before g

If you pronounce the vowels clearly and keep the penultimate stress, you will already sound much more natural.
