انا مش محتاج سكر، لكن عايز بسكوت مع الشاي.

It is Egyptian Arabic.

Clues:

• مش is the common Egyptian negator here.
• عايز is a very common Egyptian word for wanting.
• The overall phrasing sounds colloquial, not formal written Arabic.

A more MSA-style version would be something like:

أنا لا أحتاج سكرًا، لكن أريد بسكويتًا مع الشاي.

In Arabic, the present-tense verb to be is usually not spoken in sentences like this.

So:

• أنا محتاج = I am in need / I need
• أنا عايز = I want

This is very normal in Egyptian Arabic.
The sentence does not need a separate word for am.

Yes, very often it can.

You can say:

مش محتاج سكر، لكن عايز بسكوت مع الشاي.

That still sounds natural if the subject is already clear from context.

However, keeping أنا can help:

• emphasize I
• make the sentence clearer
• sound a little more explicit

So both are fine.

مش is the negation word here. It makes محتاج negative:

• محتاج = needing / in need of
• مش محتاج = not needing / don’t need

In Egyptian Arabic, مش is very commonly used to negate:

• adjectives
• nouns
• states
• participle-like words such as محتاج and عايز

So أنا مش محتاج سكر is the natural Egyptian way to say I don’t need sugar.

محتاج is originally an active participle, but in everyday Egyptian it often behaves a lot like an adjective or a state word.

So أنا محتاج سكر is literally something like:

• I am needing sugar
• or I am in need of sugar

But in normal English, you would just translate it as I need sugar.

This is very common in Arabic: participles are often used to express present states.

They are close, but not the same:

• محتاج = need
• عايز = want

So in this sentence, the speaker is saying:

• I don’t need sugar
• but I do want biscuits with tea

That contrast is important:

• need = necessity
• want = preference or desire

A person could say مش محتاج سكر، لكن عايز بسكوت because they do not require sugar, but they would still like biscuits.

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

So a bare noun can often mean:

• a
• some
• any
• or just the noun in a general sense

Here:

• سكر can mean sugar or any sugar/some sugar
• بسكوت can mean biscuits / some biscuits

The exact meaning depends on context.

This is a very common thing in Arabic, and it does not always match English exactly.

• سكر is indefinite here: sugar in general
• بسكوت is also indefinite: some biscuits / biscuits
• الشاي literally has the on it, but in Arabic that can still refer to tea in a general, familiar sense

So الشاي does not always mean a specific tea already mentioned in the conversation. In Egyptian Arabic, drinks and foods are often used with الـ even when English would just say tea.

So مع الشاي is best understood as with tea, not necessarily with the tea in a strongly specific English sense.

In everyday Egyptian, بسكوت often works as a general or collective word, similar to biscuits/cookies.

So in this sentence, it most likely means:

• some biscuits
• biscuits in general

If you want to make one biscuit clearly singular, many speakers would say بسكوتة.

So:

• بسكوت = biscuits / biscuit as a general item
• بسكوتة = one biscuit

لكن is understandable and correct, but in very casual Egyptian many people would more often say بس for but.

So a very colloquial version could be:

أنا مش محتاج سكر، بس عايز بسكوت مع الشاي.

Both are fine:

• لكن = a bit more neutral or slightly more formal
• بس = very common in everyday speech

Here مع الشاي means with tea in the sense of alongside tea.

So the idea is:

• biscuits to eat with tea

If you wanted to say something goes inside the tea, you would usually use في instead:

• سكر في الشاي = sugar in the tea

So:

• مع الشاي = together with tea
• في الشاي = in the tea

The words محتاج and عايز would usually change to the feminine forms:

أنا مش محتاجة سكر، لكن عايزة بسكوت مع الشاي.

So:

• masculine speaker: محتاج / عايز
• feminine speaker: محتاجة / عايزة

This kind of agreement is very important in Egyptian Arabic.

A simple pronunciation guide is:

ana mish meḥtāg sokkar, lākin ʿāyez baskūt maʿa sh-shāy

A few notes:

• مش sounds like mish
• محتاج ends with a hard g sound in Egyptian
• عايز is roughly ʿāyez
• بسكوت is baskoot
• الشاي is ish-shāy or sh-shāy depending on what comes before it

A natural rhythm would be:

ana mish meḥtāg sokkar, lākin ʿāyez baskūt maʿa sh-shāy
