عندي جاكت اخضر.

Literally, عندي means at me or by me.

Egyptian Arabic often expresses possession with عند + a pronoun ending:

• عندي = I have
• عندك = you have
• عنده = he has
• عندها = she has

So instead of using a verb exactly like English have, Arabic often uses this possession structure.

It can, but it does not have to.

The -ي at the end of عندي already means me, so the subject is understood. That makes أنا optional.

• عندي جاكت اخضر = I have a green jacket
• أنا عندي جاكت اخضر = I have a green jacket

Adding أنا can give extra emphasis, but leaving it out is very normal.

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

So a bare noun like جاكت can mean a jacket. Context tells you it is indefinite.

That means:

• جاكت = a jacket
• الجاكت = the jacket

Because that is the normal word order in Arabic.

In English, you say:

• green jacket

In Arabic, you usually say:

• jacket green → جاكت اخضر

So the adjective follows the noun.

Yes, Arabic nouns have grammatical gender, even when English nouns do not.

In this sentence, جاكت is being treated as masculine, so the adjective is also masculine:

• اخضر / أخضر = masculine green

With loanwords, gender can sometimes vary in colloquial Arabic, but this sentence clearly uses masculine agreement.

For comparison:

• masculine: أخضر
• feminine in Egyptian colloquial: خضرا
• feminine in Standard Arabic: خضراء

Yes, in more careful spelling, it is usually written أخضر.

But in everyday typing, especially in dialect writing, people often leave off the hamza and write:

• اخضر

So اخضر and أخضر are the same word here. Informal Arabic spelling, especially for dialect, is less standardized than formal Standard Arabic.

A rough pronunciation is:

ʿandi gaket akhdar

A few important sounds:

• ع in عندي is a deep throat sound with no exact English equivalent
• ج in Egyptian Arabic is usually pronounced like hard g in go
• خ in اخضر sounds like the ch in Scottish loch or German Bach
• the final ت in جاكت is pronounced

So جاكت in Egyptian sounds more like gaket/gacket than English jacket.

It is a borrowed word, used very commonly in everyday speech.

You may see different spellings, such as:

• جاكت
• جاكيت

Both are common ways of writing jacket in Arabic script.

A more formal or more purely Arabic word would be something like سترة, but جاكت/جاكيت is very natural in colloquial Egyptian.

Yes, you could.

The difference is often:

• عندي = I have / I own / I possess
• معايا = I have with me / it is on me / I am carrying it

So:

• عندي جاكت اخضر = I have a green jacket
• معايا جاكت اخضر = I have a green jacket with me

In real conversation, the difference can be small, but معايا often suggests physical possession right now.

In Egyptian Arabic, you can say:

ماعنديش جاكت اخضر

This is built with the Egyptian negation pattern ما-...-ش around عندي.

So:

• عندي = I have
• ماعنديش = I don’t have

You may also see it spaced as ما عنديش.

You would make both the noun and the adjective definite:

عندي الجاكت الاخضر

That is because in Arabic, when a noun is definite, its adjective also becomes definite.

So:

• جاكت اخضر = a green jacket
• الجاكت الاخضر = the green jacket

Because normal Arabic writing usually leaves out most short vowels.

That means learners have to know or learn the pronunciation from experience, context, or dictionaries.

For example, the script:

• عندي جاكت اخضر

does not show every vowel sound explicitly, but a speaker knows how to read it. This is completely normal in Arabic writing.

It is best understood as Egyptian colloquial Arabic.

Clues include:

• the use of the everyday loanword جاكت
• the informal spelling اخضر
• the natural spoken-style structure

A more formal Standard Arabic version might be:

• لديّ سترة خضراء
• or عندي سترة خضراء

So the sentence you gave is very natural for everyday Egyptian speech.
