Tafadhali weka sabuni ya kuosha mikono karibu na sinki.

Tafadhali means please. It softens the command and makes it polite.

Without tafadhali, weka sabuni... is still grammatical, but it sounds more direct: Put the hand soap...
With tafadhali, it becomes more like Please put the hand soap...

Kuweka is the infinitive form, meaning to put or to place.

In this sentence, weka is the imperative form used to give a command to one person. So:

• kuweka = to put
• weka = put!

That is why the sentence uses weka.

In Swahili, commands usually do not need an explicit subject pronoun. The verb form itself already tells you that it is a command.

So weka by itself means put! and naturally implies you.

English often needs the implied subject understood as you, but Swahili does not add a separate word for it here.

If you are speaking to more than one person, the imperative changes from weka to wekeni.

So the sentence becomes:

Tafadhali wekeni sabuni ya kuosha mikono karibu na sinki.

That means Please put the hand soap near the sink when addressing multiple people.

Literally, it means something like soap for washing hands.

Breaking it down:

• sabuni = soap
• ya = of / for
• kuosha = to wash
• mikono = hands

So sabuni ya kuosha mikono is a natural way to say hand-washing soap or soap for washing hands.

Here, ya links sabuni with the phrase that describes its purpose.

So sabuni ya kuosha mikono means soap for washing hands. In English, we often use a noun modifier like hand soap, but Swahili commonly uses a structure like noun + ya + infinitive phrase to show purpose or association.

In other words, ya is helping connect soap with washing hands.

Mkono means hand or arm in the singular.
Mikono is the plural: hands.

Since the soap is for washing hands in general, the plural mikono is used.

This follows a common noun pattern in Swahili:

• mkono = hand
• mikono = hands

Karibu na means near, close to, or next to.

So:

• karibu na sinki = near the sink

Be careful not to confuse this with karibu used by itself in greetings or hospitality, where it can mean welcome or come in. In this sentence, karibu na is clearly the location phrase meaning near.

Sinki is a loanword, borrowed from English sink.

Swahili uses many loanwords, especially for modern objects. This is completely normal. So sinki is a standard and understandable word for sink.

That word order is very normal in Swahili.

Here the sentence is arranged as:

• Tafadhali = please
• weka = put
• sabuni ya kuosha mikono = the hand soap / soap for washing hands
• karibu na sinki = near the sink

So it follows a very natural pattern:

Please + put + thing + place

That is one of the reasons this sentence feels quite straightforward to English speakers.

Yes, in many contexts sabuni ya mikono can also be understood as hand soap.

However, sabuni ya kuosha mikono is more explicit. It clearly means soap for washing hands. That can be especially helpful for learners, or when you want to be very clear about the soap’s purpose.

So:

• sabuni ya mikono = hand soap
• sabuni ya kuosha mikono = soap for washing hands

Both can work, but the second is more descriptive.

Kuosha is pronounced roughly koo-OH-sha.

The uo sequence is pronounced smoothly, but both vowels are still there. Swahili vowels are usually pronounced clearly, unlike in English where vowels often reduce or blur.

A rough pronunciation of the whole sentence is:

ta-fa-DHA-li WE-ka sa-BU-ni ya ku-O-sha mi-KO-no ka-RI-bu na SIN-ki

The dh in tafadhali sounds like the th in this, not like the th in thin.

It is polite and neutral.

The presence of tafadhali makes it courteous, but the sentence is still simple and practical. It sounds appropriate for everyday situations such as a home, office, classroom, or public restroom.

It is not overly formal, and it is not rude. It is a very natural polite instruction.
