الغلاف جديد والطبعة قديمة.

A common Egyptian-style pronunciation would be:

il-ghilāf gidīd wiṭ-ṭabʿa ʔadīma

A few quick notes:

• جديد is usually pronounced gidīd in Egyptian, with a hard g.
• قديمة is often pronounced ʔadīma in Cairene Egyptian, because ق often becomes a glottal stop.
• الطبعة is pronounced iṭ-ṭabʿa / eṭ-ṭabʿa, not al-tabʿa, because of sound assimilation.
• Exact vowels can vary a bit by region and speaker.

In Arabic, present-tense sentences like this often do not use a separate word for is/are.

So:

• الغلاف جديد = The cover is new
• الطبعة قديمة = The edition is old

This is very normal in both Egyptian Arabic and Standard Arabic.

If you wanted past tense, then you would use a verb such as كان:

• الغلاف كان جديد = The cover was new

Because الغلاف and الطبعة are the things being talked about, while جديد and قديمة are the predicates describing them.

In a sentence like this:

• الغلاف جديد = The cover is new

the predicate adjective is normally indefinite, so it does not take الـ.

Compare these two patterns:

• الغلاف جديد = The cover is new
• الغلاف الجديد = the new cover

That is a very important difference:

• noun + adjective without ال can be a full sentence
• noun + adjective with matching ال is a noun phrase

Because adjectives in Arabic agree with the noun in gender.

• غلاف is masculine, so you use جديد
• طبعة is feminine, so you use قديمة

A common clue is the ending ـة:

• طبعة ends in ـة, so it is feminine
• the adjective also becomes feminine: قديمة

If the second noun were masculine, you would use قديم instead.

Because ط is a sun letter.

When الـ comes before a sun letter, the l sound is not pronounced. Instead, the next consonant is doubled.

So:

• الطبعة is written with ال
• but pronounced roughly iṭ-ṭabʿa / eṭ-ṭabʿa

By contrast, غ in الغلاف is a moon letter, so the l is pronounced there:

• الغلاف → il-ghilāf

This written-vs-pronounced difference is extremely common in Arabic.

In Egyptian Arabic, the conjunction و is often pronounced wi or sometimes just a short w/u sound, depending on what follows and on the speaker.

So:

• والطبعة may sound like wiṭ-ṭabʿa

This is just the normal Egyptian pronunciation of and in connected speech.

In Standard Arabic, learners often first meet it as wa, but in Egyptian everyday speech wi is very common.

Because in many Egyptian accents, especially Cairene Arabic, the letter ق is often pronounced as a glottal stop ʔ rather than q.

So:

• قديم becomes ʔadīm
• قديمة becomes ʔadīma

In Standard Arabic, you would pronounce it more like qadīma.

So the spelling stays the same, but the pronunciation changes by dialect.

The ع in طبعة is the sound written as ʿ in transliteration: ṭabʿa.

For English speakers, this is often one of the hardest Arabic sounds. A simple practical tip:

• don’t replace it with a full English vowel
• try making a brief, tight sound in the throat while moving from b to the final a

You do not need perfect pronunciation immediately. If you say something close to tab-a at first, people may still understand you, but it is worth gradually training yourself to hear and produce ʿ.

Yes. The basic wording works in both.

What mainly changes is the pronunciation:

• Egyptian: il-ghilāf gidīd wiṭ-ṭabʿa ʔadīma
• More Standard-style pronunciation: al-ghilāf jadīd waṭ-ṭabʿa qadīma

In full formal Standard Arabic, you might also hear case endings in careful speech:

• al-ghilāfu jadīdun waṭ-ṭabʿatu qadīmatun

But in normal conversation, those endings are usually dropped, and the sentence looks very much like this.
