حط مسحوق الغسيل ومنعم الهدوم في الغسالة.

حط means put / place.

In this sentence, it is the imperative form, so it is a command: Put ...

In Egyptian Arabic, حط is the normal everyday verb for to put. It is very common in speech.

A useful detail: this form is usually understood as singular masculine.
Other common forms are:

• حطي = put ... (to one woman)
• حطوا = put ... (to more than one person)

It is usually pronounced ḥoṭṭ, with a doubled t sound.

Because in Arabic, especially in commands, it is very natural to start with the verb.

So:

• حط مسحوق الغسيل... = Put the detergent...

This verb-first order is very normal in Arabic. English can also do this in commands, so this part actually matches English pretty well.

حط is the Egyptian Arabic everyday word.
ضع is the more formal Modern Standard Arabic (MSA) version.

So:

• حط = colloquial Egyptian, natural in daily speech
• ضع = formal / written / Standard Arabic

A native speaker giving a real-life instruction would very likely say حط, not ضع.

Literally, مسحوق الغسيل means something like washing powder or laundry detergent.

It is made of two nouns:

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

Together they form an iḍāfa construction, which is a very common Arabic noun pattern:

• مسحوق الغسيل = laundry detergent / washing powder

Even if the detergent is not literally powder in every situation, this phrase is often used as the normal name for laundry detergent.

منعم الهدوم means fabric softener.

Literally:

• منعم = softener
• الهدوم = clothes

So the whole phrase is literally clothes softener.

This is also an iḍāfa construction:

• منعم الهدوم = fabric softener

In everyday Egyptian Arabic, this is a very natural way to say it.

Because الهدوم is the everyday Egyptian Arabic word for clothes.

• هدوم = clothes, everyday Egyptian
• ملابس = clothes, more formal / Standard Arabic

So if you want to sound natural in Egyptian conversation, هدوم is very useful.

A learner will hear هدوم much more often in casual speech.

This is because both expressions are being used as noun compounds in an iḍāfa structure:

• مسحوق الغسيل
• منعم الهدوم

In Arabic, the first noun in an iḍāfa often appears without ال.

So:

• مسحوق الغسيل = laundry detergent
• منعم الهدوم = fabric softener

This is normal Arabic structure, not a mistake.

If you added ال to the first noun, the meaning or feel would shift, often making it sound more specifically like the detergent or the softener, depending on context.

Yes. Here في means in.

So:

• في الغسالة = in the washing machine

After a verb like حط (put), Arabic commonly uses في to show where something is being placed.

So the structure is:

• حط X في Y
• put X in Y

That matches English very closely.

It is commonly pronounced something like el-ghassāla.

A few useful points:

• ال in Egyptian is usually pronounced el- or il-, not al-
• غ is a deep throaty sound, often written gh
• the س is doubled in pronunciation here

So:

• الغسالة → el-ghassāla

It means the washing machine.

A natural pronunciation would be roughly:

ḥoṭṭ masḥūʔ il-ghasīl wi-munaʕʕim il-hudūm fil-ghassāla

A few notes:

• حط = ḥoṭṭ
• و often sounds like wi in Egyptian speech
• في الغسالة often runs together as fil-ghassāla

You do not need to pronounce it in a super careful word-by-word way. In normal speech, it flows smoothly.

Yes, it strongly sounds like Egyptian Arabic.

The biggest clues are:

• حط for put
• الهدوم for clothes
• the general colloquial style

A more formal MSA version might be something like:

• ضع مسحوق الغسيل ومنعّم الملابس في الغسالة

But the original sentence is much more natural for everyday Egyptian speech.

Yes.

The command form changes depending on who you are addressing:

• حط = to one man
• حطي = to one woman
• حطوا = to a group

So you could say:

• حطي مسحوق الغسيل ومنعم الهدوم في الغسالة
  = said to one woman

• حطوا مسحوق الغسيل ومنعم الهدوم في الغسالة
  = said to a group

This is very useful, because Arabic imperatives regularly change for gender and number.
