مسحوق الغسيل جنب الغسالة.

A natural Egyptian pronunciation is:

masḥūʔ il-ghasīl gamb il-ghasāla

A few notes:

• مسحوق → masḥūʔ
  The final written ق is often pronounced as a glottal stop ʔ in Egyptian Arabic.
• الغسيل → il-ghasīl
• جنب → gamb in Egyptian
  In more formal Arabic, this is usually janb.
• الغسالة → il-ghasāla

A smooth full pronunciation would sound something like:

masḥūʔ il-ghasīl gamb il-ghasāla

Because in Arabic, especially in the present tense, to be is usually not spoken.

So:

• مسحوق الغسيل جنب الغسالة literally looks like:
• Laundry detergent next to the washing machine

But it means:

• The laundry detergent is next to the washing machine

This is completely normal in Arabic.
If you want the past or future, then forms of كان and other verbs can appear, but in a simple present statement, no is/am/are is needed.

جنب means:

• next to
• beside
• sometimes by

In Egyptian Arabic, it is very commonly pronounced gamb.

So:

• جنب الغسالة = next to the washing machine

It is one of the most common ways to express location.

Examples:

• الكرسي جنب الباب = The chair is next to the door
• الموبايل جنبك = The phone is next to you

That is a dialect feature of Egyptian Arabic.

In Egyptian Arabic:

• the letter ج is usually pronounced like g in go
• so جنب becomes gamb

In Modern Standard Arabic, you would usually hear something closer to:

• janb

So this is a very useful word for recognizing the difference between Egyptian and more formal Arabic.

Literally, it is:

• مسحوق = powder
• الغسيل = the washing / the laundry

So the literal sense is something like:

• washing powder
• laundry powder

In real usage, it often means:

• laundry detergent
• washing powder

Even if the English translation shown to the learner is laundry detergent, the Arabic expression may still literally contain the idea of powder.

They come from the same root related to washing, but they mean different things:

• الغسيل = the laundry / the washing
• الغسالة = the washing machine

So:

• مسحوق الغسيل = laundry detergent / washing powder
• الغسالة = the washing machine

This is a good example of how Arabic builds related words from the same root.

الـ is the Arabic definite article, meaning the.

In this sentence:

• الغسيل = the laundry / the washing
• الغسالة = the washing machine

Arabic often uses the in places where English may or may not use it, especially in fixed expressions.

For example:

• مسحوق الغسيل is a standard expression for laundry detergent / washing powder
• It does not necessarily sound overly specific the way the sometimes does in English

So even though English might say laundry detergent, Arabic commonly says something literally closer to powder of the laundry.

Yes. This is a complete and very normal Arabic sentence.

It is a type of nominal sentence: a sentence built around nouns or noun-like elements rather than an expressed verb.

Structure here:

• مسحوق الغسيل = the topic / thing being talked about
• جنب الغسالة = where it is

So the whole sentence is complete:

• The laundry detergent is next to the washing machine

This kind of sentence is extremely common in Arabic.

Yes, but the meaning or focus may shift.

Original:

• مسحوق الغسيل جنب الغسالة
• The laundry detergent is next to the washing machine

If you say:

• الغسالة جنب مسحوق الغسيل that means:
• The washing machine is next to the laundry detergent

In English, these two are often practically the same in real life, but grammatically the subject has changed.
So the word order matters because it changes what the sentence is primarily saying something about.

A more formal version would usually be:

مسحوق الغسيل بجانب الغسالة

or

مسحوق الغسيل إلى جانب الغسالة

Why?

• Egyptian Arabic commonly uses جنب / gamb
• Modern Standard Arabic more often uses بجانب / bijānib or إلى جانب

Also, in MSA, جنب is more likely to be pronounced janb, not gamb.

So the Egyptian sentence is natural and everyday, while the MSA versions sound more formal.

In Egyptian Arabic, you would usually use مش.

So:

• مسحوق الغسيل مش جنب الغسالة = The laundry detergent is not next to the washing machine

This is the normal simple negation for a sentence like this in Egyptian Arabic.

Usually جنب suggests beside or next to, so it often feels a bit closer than just near.

• جنب = right by / beside / next to

If you want to say something more like near, Egyptian Arabic often uses:

• قريب من = near / close to

So:

• مسحوق الغسيل جنب الغسالة = the detergent is right next to the machine
• مسحوق الغسيل قريب من الغسالة = the detergent is near the machine

In everyday speech, though, people may sometimes use these a little loosely depending on context.

You could turn it into a yes/no question just by using questioning intonation:

• مسحوق الغسيل جنب الغسالة؟ = Is the laundry detergent next to the washing machine?

In speech, your voice rises at the end.

If you want to ask Where is the laundry detergent?, a very natural Egyptian question is:

• مسحوق الغسيل فين؟ = Where is the laundry detergent?

And the answer could be:

• جنب الغسالة = Next to the washing machine

Not in normal spoken Egyptian Arabic.

In written or formal Modern Standard Arabic, nouns can have case endings, but in everyday Egyptian speech these are not used.

So a learner should focus on the spoken forms:

• masḥūʔ il-ghasīl gamb il-ghasāla

without worrying about case endings in conversation.

That is one reason spoken Egyptian often feels simpler than fully inflected formal Arabic.
