Baada ya kufua nguo, usivae nguo zenye unyevu.

Baada ya means after. In Swahili, baada ya is commonly followed by an infinitive verb to mean after doing something.

So:

• baada ya kufua nguo = after washing clothes

Here, kufua is the infinitive to wash clothes / to do laundry.

A useful pattern is:

• baada ya + infinitive

For example:

• baada ya kula = after eating
• baada ya kusoma = after studying
• baada ya kufika = after arriving

Both can relate to washing, but they are not exactly the same.

• kufua is especially used for washing clothes / doing laundry
• kuosha is a more general to wash

So in this sentence, kufua nguo is the natural choice because the topic is laundry.

Compare:

• kuosha mikono = to wash hands
• kuosha gari = to wash a car
• kufua nguo = to wash clothes

A learner can think of kufua as the more specific laundry verb.

It appears twice because the sentence has two different parts:

• Baada ya kufua nguo = after washing clothes
• usivae nguo zenye unyevu = do not wear clothes that are damp

So the first nguo is the object of kufua and the second nguo is the object of usivae.

Swahili often repeats nouns where English might sometimes replace them with them or leave them understood. Repeating the noun keeps the sentence clear and natural.

Usivae is a negative command directed at one person.

It comes from the verb:

• kuvaa = to wear

In a negative command, Swahili often uses:

• usi-
  • verb in the appropriate final form

So:

• usivae = don’t wear

This is singular, meaning you are telling one person not to do something.

Compare:

• vaa nguo hizi = wear these clothes
• usivae nguo hizi = don’t wear these clothes

This is because negative commands in Swahili usually use the subjunctive-type final vowel -e rather than the normal infinitive ending -a.

So from kuvaa:

• base idea: vaa = wear
• negative command: usivae = don’t wear

This pattern is very common:

• kula → usile = don’t eat
• kunywa → usinywe = don’t drink
• kusoma → usisome = don’t read
• kuvaa → usivae = don’t wear

Yes. Usivae is for one person. If you are speaking to more than one person, you would say:

• msivae nguo zenye unyevu

So:

• usivae = don’t wear (singular)
• msivae = don’t wear (plural)

This is a very useful distinction in Swahili, since commands often show whether you are addressing one person or several.

Zenye means something like that have or which have.

So:

• nguo zenye unyevu = clothes that have moisture / clothes that are damp

It agrees with nguo, which belongs to the N class and takes agreement like zi-/z- in the plural sense here.

That is why you get zenye, not something like wenye or enye.

A good way to understand it is:

• -enye = having, with
• z-enye = having/with, agreeing with nguo

You will see similar forms with other noun classes:

• mtu mwenye pesa = a person who has money
• kitu chenye maji = a thing with water
• nguo zenye unyevu = clothes with moisture

Unyevu means moisture, dampness, or wetness.

In this sentence, it refers to clothes still being a bit wet or damp after washing.

So:

• nguo zenye unyevu = damp clothes / clothes with moisture

This is a noun, not an adjective by itself in this sentence. Swahili often expresses ideas like damp clothes through a structure like:

• clothes that have moisture

rather than using a simple adjective exactly like English does.

Here it is understood as plural: clothes.

But an important thing to know is that nguo often has the same form in singular and plural. The form itself does not change, so context tells you whether it means:

• a garment/item of clothing
• or clothes/clothing

In this sentence, the meaning is clearly plural or collective, since we are talking about laundry and wearing clothes in general.

The agreement word zenye also helps show that the sense here is plural/class 10.

Yes, in many everyday contexts that is a perfectly natural translation, especially if the clothes are still not dry.

But more literally:

• nguo zenye unyevu = clothes with moisture / damp clothes

So damp clothes is often the most precise translation. Wet clothes may sound a bit stronger in English, as if they are very wet, while unyevu can suggest they are still moist or not fully dry.

Yes, Swahili allows some flexibility in word order, especially with time phrases like baada ya kufua nguo.

For example, this is also understandable:

• Usivae nguo zenye unyevu baada ya kufua nguo.

But the original version:

• Baada ya kufua nguo, usivae nguo zenye unyevu.

is very natural because it sets the time/context first: After washing clothes...

That structure is especially common when giving advice or instructions.

The comma is helpful, but in ordinary writing it is not always absolutely required.

It marks the introductory phrase:

• Baada ya kufua nguo, ...

This is similar to English, where we often put a comma after an opening phrase like After washing the clothes, ...

So the comma makes the sentence easier to read, but the meaning would still be clear without it.
