الخياطة على البطانة.

It is most naturally understood as a phrase or label, not a complete everyday sentence.

In Arabic, especially in:

• captions
• instructions
• tailoring notes
• headings

you can often get just a noun phrase like this without a verb.

So this can sound like:

• a note on a sewing diagram
• a section title
• a brief instruction label

If you wanted a fuller Egyptian-style sentence, you might say something like:

• الخياطة بتكون على البطانة = The sewing is on the lining
• or an imperative such as خيّط على البطانة = Sew on the lining

A natural Egyptian-style pronunciation would be approximately:

el-khiyāṭa ʿala l-baṭāna

A few pronunciation notes:

• خ = a throaty kh sound, like in Scottish loch or German Bach
• ع = the Arabic ʿayn, a deep throat sound with no exact English equivalent
• ط = an emphatic t, heavier/darker than normal t
• ة at the end is usually pronounced -a when you pause

So:

• الخياطة → el-khiyāṭa
• على → ʿala
• البطانة → el-baṭāna or, in connected speech after ʿala, often ʿala l-baṭāna

الخياطة is a noun, specifically a verbal noun or masdar.

It comes from the verb related to sewing. So grammatically, it behaves like a noun meaning:

• sewing
• the sewing
• sometimes tailoring, depending on context

In this phrase, it is not a verb. That is why there is no tense here like is sewing or sewed.

Because both nouns are definite.

الـ is the Arabic definite article, equivalent to the.

So:

• الخياطة = the sewing
• البطانة = the lining

Arabic often uses definiteness differently from English. A phrase can sound natural with the on both nouns even where English might not always say the twice.

In a context like a sewing instruction or diagram, both items are usually understood as specific:

• the sewing being discussed
• the lining of the garment being discussed

على usually means on, on top of, or onto, depending on context.

Here it shows the relationship between the sewing and the lining:

• the sewing is on the lining
• or the sewing is done onto the lining

This is a very common preposition in Arabic, and in Egyptian Arabic it is usually pronounced ʿala.

That ending is called taa marbuuTa: ة.

In words like these, it very often marks a feminine noun.

So:

• خياطة
• بطانة

are both feminine nouns.

In pronunciation, ة is usually:

• -a when you stop at the word
• -t when another ending is attached or in certain grammatical combinations

For example:

• خياطة → khiyāṭa
• but in a construction like خياطة الملابس you would hear the t more clearly: khiyāṭat il-malābis

It can work in both, but it feels neutral and fairly standard in wording.

The main differences are in pronunciation, not in the written words.

For example:

• In Standard Arabic, you might pronounce it closer to al-khiyāṭa ʿalā al-biṭāna
• In Egyptian Arabic, it would more naturally sound like el-khiyāṭa ʿala l-baṭāna

So a learner might see this written form in either context, but pronounce it differently depending on whether they are aiming for MSA or Egyptian.

Because normal Arabic writing usually leaves out most short vowels.

So the written form: الخياطة على البطانة

does not show all the pronunciation details.

Also, in Egyptian Arabic, grammatical case endings are not used in speech.

In very formal Standard Arabic, the fully vocalized version could be something like:

• الخياطةُ على البطانةِ

But in everyday reading and all normal Egyptian pronunciation, you do not say those case endings.

Yes.

Depending on context, الخياطة can refer to:

• sewing as an action
• stitching
• tailoring
• the craft of sewing

So learners may see it translated a little differently in different contexts. In a clothing or fabric context, the exact English choice depends on what is being described:

• the act
• the technique
• the craft
• the stitched area

In connected speech, Arabic words often flow together.

So instead of carefully saying:

• ʿala el-baṭāna

many speakers will say something closer to:

• ʿala l-baṭāna

That does not change the meaning. It is just smoother natural pronunciation.

This kind of linking is very common in Egyptian Arabic.
