حطيت الطبق في الحوض بعد الغدا.

A natural Egyptian pronunciation is:

ḥaṭṭēt eṭ-ṭabaʔ fil-ḥōḍ baʿd il-ghada

A few notes on that transcription:

• ḥ = a stronger, breathier h sound
• ṭ = an emphatic t
• ʿ = the sound of ع
• ʔ = a glottal stop, like the break in uh-oh

You may also hear small vowel differences like el-/il- depending on the speaker.

حطيت means I put or I placed.

It comes from the verb حطّ = to put / to place.

The ending -يت marks I in the past tense, so:

• حطّ = he put
• حطيت = I put

Depending on context, English might translate it as I put or I’ve put, but the basic meaning here is simple past.

Because in Arabic, the verb itself often already tells you the subject.

In حطيت, the ending shows that the subject is I, so أنا is not necessary.

You could say:

أنا حطيت الطبق في الحوض بعد الغدا

but that usually adds emphasis, like I put the plate...

Because everyday Arabic writing usually leaves out most diacritics.

So in normal spelling:

• حطيت is written without vowel marks
• but it is pronounced ḥaṭṭēt
• and الطبق is written without showing the full pronunciation, but is pronounced eṭ-ṭabaʔ

Native speakers know the pronunciation from experience and context.

Yes. Starting with the verb is very normal in Arabic.

So:

حطيت الطبق في الحوض بعد الغدا

is completely natural.

You can also put the subject first:

أنا حطيت الطبق في الحوض بعد الغدا

That version is also natural, but it gives a little more emphasis to I.

In Egyptian Arabic, الطبق is usually pronounced something like:

eṭ-ṭabaʔ

Two important things are happening:

• ال becomes eṭ- here because ط is a sun letter, so the l sound of ال assimilates to the next consonant.
• The final ق is often pronounced as a glottal stop in Cairene Egyptian, so طبق becomes ṭabaʔ.

So although the spelling is الطبق, the spoken form is closer to eṭ-ṭabaʔ.

It can mean either, depending on context.

In this sentence, الطبق most naturally means the plate.

In other situations, طبق can also mean dish, especially in a more general sense.

That’s very normal in Egyptian Arabic.

After verbs like حطّ (to put), Arabic commonly uses في where English might use in or into.

So:

حطيت الطبق في الحوض

naturally means I put the plate in / into the sink.

Arabic does not always make the same in vs into distinction that English does.

الحوض literally means something like basin or trough, but in everyday home language it usually means the sink.

So here:

في الحوض = in the sink

Its pronunciation is usually something like il-ḥōḍ or el-ḥōḍ.

Unlike الطبق, the ل of ال is pronounced here, because ح is a moon letter, not a sun letter.

In this sentence, الغدا means lunch.

This can be confusing if you know some Modern Standard Arabic, because غدًا in formal Arabic means tomorrow.

But in Egyptian Arabic:

• الغدا = lunch
• بكرة = tomorrow

So here بعد الغدا definitely means after lunch, not after tomorrow.

Because this is colloquial Egyptian spelling, not formal Modern Standard Arabic spelling.

In formal Arabic, lunch is usually written:

الغداء

But in everyday Egyptian writing, people often simplify spellings, and the final hamza is commonly left off:

الغدا

Both point to the same word here: lunch.

Because Egyptian Arabic does not use the full case-ending system of Modern Standard Arabic in normal speech.

So you get forms like:

• الطبق
• الحوض
• الغدا

without endings like -u, -a, or -i.

That is completely normal in spoken Egyptian Arabic.

Yes, this is clearly colloquial Egyptian Arabic.

A more formal Modern Standard Arabic version would be:

وضعتُ الطبقَ في الحوضِ بعدَ الغداءِ

Main differences:

• حطيت is colloquial Egyptian; وضعتُ is formal
• الغدا is colloquial spelling/pronunciation; الغداء is formal
• formal Arabic uses case endings, while Egyptian everyday speech does not

So the original sentence is the kind of thing you would actually hear in everyday Egyptian conversation.
