ماما عملت طبق بطاطس للفطار.

A natural pronunciation would be something like:

mama ʿamalet ṭabaʔ baṭāṭes lel-faṭār

A few helpful notes:

• ماما = mama
• عملت = ʿamalet
  The ع is the deep throat sound ʿ.
• طبق = ṭabaʔ
  In Egyptian Arabic, ق is often pronounced like a glottal stop, so this sounds like ṭabaʔ rather than ṭabaq.
• بطاطس = baṭāṭes
• للفطار = lel-faṭār
  Even though it is written with ل + الفطار, in speech it comes out as lel-faṭār.

Because the subject ماما is feminine.

In the past tense, Egyptian Arabic marks gender on the verb:

• عمل = he did / he made
• عملت = she did / she made

So:

• ماما عملت = Mom made
• If the subject were masculine, you would say something like بابا عمل = Dad made

Here it means made.

The verb عمل is very common in Egyptian Arabic and can mean both:

• to do
• to make

The exact meaning depends on context.

In this sentence, since the object is food, made is the natural meaning:

• ماما عملت طبق بطاطس = Mom made a potato dish

Because Arabic does not have an indefinite article like English a/an.

So:

• طبق can mean a dish
• الطبق means the dish

In this sentence, طبق has no الـ, so it is indefinite: a dish.

It can mean both, depending on context.

Common meanings of طبق include:

• plate
• dish
• a prepared food dish

In طبق بطاطس, it means a potato dish or a dish of potatoes, not just a physical plate.

So context tells you which meaning is intended.

Because Arabic often puts two nouns next to each other to make a phrase like:

• طبق بطاطس = a potato dish
• literally, something like dish potatoes

This kind of noun combination is very common. English often uses of or an adjective, but Arabic often does not need an extra word here.

So طبق بطاطس sounds natural in Egyptian Arabic.

If you added من in many cases, it would sound more literal, like a dish made from potatoes, which is possible in some contexts, but less natural for this simple sentence.

بطاطس means potatoes, but in everyday Arabic it often works like a general food word, similar to how English sometimes says potato or potatoes depending on the phrase.

So:

• بطاطس = potatoes
• طبق بطاطس = a potato dish / a dish of potatoes

In real usage, learners should treat بطاطس as the normal everyday word for the food item potatoes.

Here لـ means for.

So:

• للفطار = for breakfast

It is made of:

• لـ = for
• الفطار = the breakfast

Together:

• للفطار = for breakfast

In pronunciation, this usually sounds like lel-faṭār in Egyptian Arabic.

Yes. In Egyptian Arabic, فطار is the normal everyday word for breakfast.

So:

• فطار = breakfast
• الفطار = the breakfast

In the phrase للفطار, English translates it simply as for breakfast, even though Arabic uses the definite form.

This is very normal. Arabic often uses the where English does not.

Because in Egyptian Arabic, subject-first word order is very common.

So:

• ماما عملت طبق بطاطس للفطار = Mom made a potato dish for breakfast

This is very natural in spoken Egyptian.

You may also see verb-first order in Arabic more generally, especially in more formal styles, but in everyday Egyptian speech, starting with the subject is extremely common.

Yes, you could, but the feeling changes a little.

• ماما is very common, warm, and conversational: Mom / Mommy / Mama
• أمي means my mother and can sound more formal or more written

So in natural everyday Egyptian speech, ماما is very believable and common.

Because this is Egyptian Arabic, not formal written Modern Standard Arabic.

In Egyptian Arabic:

• case endings are not used the way they are in MSA
• words are pronounced in a shorter, more streamlined way
• everyday speech drops many formal endings

That is why the sentence looks and sounds simpler than formal Arabic grammar charts might lead you to expect.

Yes, it strongly feels Egyptian colloquial.

A few clues are:

• ماما as a very everyday spoken word
• الفطار for breakfast, which is very natural in Egyptian
• the overall simple spoken-style structure

A Modern Standard Arabic sentence with a similar meaning would usually be phrased a bit differently. So this sentence is best understood as natural spoken Egyptian Arabic.
