Tafadhali, weka kifaa hiki mezani.

Tafadhali means please. It is used to make the command more polite.

In Tafadhali, weka kifaa hiki mezani, the speaker is giving an instruction, but tafadhali softens it, just like please in English.

You can often place tafadhali at the beginning of a sentence, and that is very common.

Weka is the imperative form of the verb -weka, which means to put, to place, or to set.

So weka means put! or place! when speaking directly to one person.

This is a basic command form in Swahili:

• -weka = to put / place
• weka! = put! / place!

In Swahili, the imperative usually does not need an explicit subject. The person being addressed is understood automatically.

So:

• Weka already means put (you)!
• You do not need to add a separate word for you

This is similar to English commands:

• Put the device on the table.
• English also usually leaves out you, even though it is understood.

Kifaa is a noun meaning device, tool, or instrument, depending on context.

Grammatically, it belongs to the ki-/vi- noun class in Swahili. This is important because words that go with the noun, such as demonstratives and adjectives, must agree with that noun class.

For example:

• singular: kifaa = device
• plural: vifaa = devices

That noun class agreement is why the next word is hiki, not some other form.

In Swahili, demonstratives like this often come after the noun.

So:

• kifaa hiki = this device

This is a very normal Swahili word order:

• noun first
• demonstrative after it

Compare:

• kitabu hiki = this book
• kiti hiki = this chair
• kifaa hiki = this device

Hiki means this, but it is specifically the form that agrees with nouns in the ki-/vi- class when they are singular.

Since kifaa is a ki- class noun, the correct demonstrative is hiki:

• kifaa hiki = this device

Different noun classes use different forms of this:

• mtu huyu = this person
• meza huu = this table
• kitabu hiki = this book

So hiki is chosen because it matches the noun class of kifaa.

Mezani means something like on the table, at the table, or on the tabletop, depending on context.

It comes from:

• meza = table
• -ni = a locative ending, often meaning in, at, or on

So:

• meza = table
• mezani = at/on the table

In this sentence, the natural English meaning is on the table.

Not always. The locative ending -ni is broader than the English word on. It can mean:

• in
• at
• on
• sometimes just in the area of or at the place of

The exact meaning depends on the noun and the context.

Examples:

• nyumbani = at home / in the house
• shuleni = at school
• mezani = on the table / at the table

So in this sentence, mezani is best understood as on the table, but the ending itself is more flexible than a single English preposition.

Because Swahili often expresses location through the locative ending -ni instead of using a separate preposition like English does.

English says:

• on the table

Swahili says:

• mezani

So the idea of location is built into the noun form itself, rather than being expressed with a separate word.

Yes, it is very typical.

The sentence follows a natural pattern:

• Tafadhali = please
• weka = put
• kifaa hiki = this device
• mezani = on the table

So the structure is basically: Please + verb + object + location

That is a very normal way to form this kind of sentence in Swahili.

Yes. If you remove tafadhali, the sentence becomes:

Weka kifaa hiki mezani.

That still means Put this device on the table, but it sounds more direct and less polite.

So:

• Tafadhali, weka kifaa hiki mezani. = polite request
• Weka kifaa hiki mezani. = direct command

You would need to change the noun and the demonstrative to the plural form.

• singular: kifaa hiki = this device
• plural: vifaa hivi = these devices

So the sentence would be:

Tafadhali, weka vifaa hivi mezani.

Notice the agreement:

• kifaa → vifaa
• hiki → hivi

A simple pronunciation guide is:

• kifaa ≈ kee-FAA
• hiki ≈ HEE-kee

A few helpful points:

• Swahili vowels are usually pronounced clearly and consistently.
• ki sounds like kee
• hi sounds like hee
• In kifaa, the aa is a long vowel sound

So kifaa hiki sounds roughly like kee-FAA HEE-kee.

It is normal, clear, and natural Swahili. It works well in everyday situations, especially if you want to be polite.

Tafadhali makes it courteous, and the rest of the sentence is straightforward and standard.

So this is a very useful model sentence for everyday polite instructions.
