في زهرتين حمرا عالبلكون جنب الشجرة الصغيرة.

Here في means there is / there are, not just in.

In Levantine, when في comes at the start of a sentence, it often introduces existence:

• في ولد هون = there is a boy here
• في ناس برا = there are people outside

So في زهرتين... means there are two flowers...

زهرتين is the dual form of زهرة, so it means two flowers.

Breakdown:

• زهرة = a flower
• زهرتين = two flowers

Because زهرة is feminine, the dual ending appears as -تين here.

Also, in everyday Levantine, the dual usually uses an -ēn / -ين type ending in most situations, so زهرتين is the normal spoken form.

Because adjectives normally come after the noun in Arabic.

So:

• زهرتين حمرا = two red flowers

This is the opposite of English, where the adjective usually comes first:

• red flowers

That noun-then-adjective order is one of the most important word-order differences to get used to in Arabic.

In everyday Levantine, adjective agreement is often less strict than in formal Arabic, especially in casual speech. With color words, speakers very often use a common everyday form like حمرا even when the noun is dual or plural.

So زهرتين حمرا sounds natural in spoken Levantine.

A useful way to think about it is:

• formal Arabic usually keeps fuller agreement
• spoken Levantine often simplifies it

You may hear some variation depending on region and speaker, but حمرا here is very normal colloquial usage.

عالبلكون is short for على البلكون.

This is a very common spoken contraction:

• على becomes عَ
• عَ + ال becomes عال

So:

• عالبلكون = on the balcony
• عالطاولة = on the table
• عالطريق = on the road

This kind of contraction is extremely common in Levantine speech.

It is a very common dialect word, and it is a loanword used in Levantine for balcony.

You should know both of these:

• بلكون = common in Levantine speech
• شرفة = more formal / MSA-style word for balcony

So in daily conversation, بلكون sounds very natural.

جنب means next to, beside, or near.

So:

• جنب الشجرة الصغيرة = next to the small tree

It is very common in Levantine and is used directly before the thing being referred to.

You can think of it as giving the location of the flowers in relation to the tree.

Because in Arabic, adjectives match the noun in definiteness.

So:

• شجرة صغيرة = a small tree
• الشجرة الصغيرة = the small tree

Since the noun is definite, الشجرة, the adjective also has to be definite: الصغيرة.

This is a basic rule in Arabic adjective phrases.

Because Arabic usually does not use a present-tense verb to be the way English does.

English says:

• there are two flowers

Levantine can simply say:

• في زهرتين

Here في already does the job of introducing existence, so no extra word for are is needed.

Yes. They mean the same thing.

• على البلكون = the fuller form
• عالبلكون = the normal connected spoken form

In real conversation, عالبلكون is what you will hear most often. The longer version may appear in careful speech, teaching materials, or more formal writing.
