طباشير الترزي عند الكم.

A rough Egyptian pronunciation is:

ṭabāšīr et-terzi ʿand el-komm

Or, more approximately for an English speaker:

ta-baa-SHEER et-TER-zi ʿand el-KOMM

A few helpful notes:

• ط is a heavier, darker t than English t
• ش sounds like sh
• ع is the consonant ʿayn, which has no exact English equivalent
• الترزي is pronounced et-terzi, not el-terzi, because ت is a sun letter
• الكم stays el-komm, because ك is not a sun letter
• The last m in الكم is doubled in pronunciation: komm

Yes. This is completely normal in Arabic.

In Arabic, especially in the present tense, sentences often do not use an explicit verb for to be. So a sentence like this can simply be:

• طباشير الترزي = the tailor’s chalk
• عند الكم = at/by the sleeve

Arabic just puts those parts together, and the meaning of is is understood automatically.

This kind of sentence is often called a nominal sentence.

Because طباشير الترزي is an iḍāfa construction, often called a genitive/possessive construction.

In an iḍāfa:

• the first noun does not take الـ
• the second noun can be definite
• if the second noun is definite, the whole phrase becomes definite

So:

• الترزي = the tailor
• طباشير الترزي = the tailor’s chalk

Even though طباشير has no الـ, the whole phrase is still definite because الترزي is definite.

This is a good question, because طباشير can look plural to learners.

In everyday usage, طباشير often works like a mass noun or collective noun, similar to English chalk. So it can refer to chalk in general, not necessarily to several separate pieces.

If you want to be very explicit about one piece of chalk, Egyptian Arabic often uses something like:

• حتة طباشير = a piece of chalk

So in this sentence, طباشير is best understood as chalk rather than as a clearly countable plural like three chalks.

Here, عند means something like:

• at
• by
• near
• with in the sense of location/presence

So عند الكم means at the sleeve or by the sleeve area.

You are also right that عند can be used to express possession in Arabic, especially with pronouns:

• عندي = I have
• عندك = you have

But that is really the same core idea of being at/with someone. In this sentence, because عند is followed by الكم, it is clearly locational, not possessive.

Here الكم means the sleeve.

In Egyptian pronunciation, it is roughly:

el-komm

Important points:

• the final m is doubled in pronunciation
• if fully marked with vowels and shadda, it would be something like الكُمّ
• without vowel marks, the spelling الكم can look ambiguous to learners

In other contexts, the same consonants can relate to quantity in more formal Arabic, but here the context makes sleeve the intended meaning.

Yes. In Egyptian Arabic, ترزي is a very common everyday word for tailor.

You may also know خيّاط, which is the more formal or standard Arabic word and is widely understood.

So very roughly:

• ترزي = common everyday Egyptian word
• خيّاط = more formal / MSA-style word

A learner will hear ترزي a lot in Egyptian speech.

This order is the most straightforward, neutral order for this sentence.

Structure:

• طباشير الترزي = the noun phrase / topic
• عند الكم = the predicate giving the location

So the sentence is basically:

• The tailor’s chalk
  • is at the sleeve

Arabic can sometimes move the location phrase earlier for emphasis or style, but طباشير الترزي عند الكم is the plain, natural way to say it.

Arabic often uses the definite article الـ in places where English also uses the, and sometimes even where English might sound slightly less definite.

Here الكم refers to a specific sleeve or sleeve area understood from the context, so the sleeve is natural in Arabic.

This is very common in Arabic: once something is identifiable from the situation, Arabic often marks it as definite.
