امي كل يوم بتحط مي للزهرة، والقطة بتقعد جنبها.

Because the -ي at the end already means my.
So:

• أم = mother
• أمي / امي = my mother / my mom

In informal Levantine writing, people often write امي without the hamza, even though the more careful spelling is أمي.

Arabic usually does not need a separate subject pronoun when the verb already shows who is doing the action.

So in:

• بتحط = she puts
• بتقعد = she sits

the verb form itself already tells you it is 3rd person feminine singular. That is why you do not need to add هي unless you want emphasis.

In Levantine Arabic, بـ on the present tense usually marks a normal present or habitual action.

So:

• تحط = she put / she puts, depending context
• بتحط = she puts / she is in the habit of putting
• بتقعد = she sits / she usually sits

Since the sentence includes كل يوم (every day), the habitual meaning fits very well.

In Arabic present-tense conjugation, تـ can mark several different persons, including she and you. Context tells you which one is meant.

Here:

• بتحط = she puts
• بتقعد = she sits

We know it means she because the subjects are أمي and القطة.

Because قطة is a feminine noun in Arabic. It also has the feminine ending ـة.

So the verb matches it in feminine singular:

• القطة بتقعد = the cat sits

Even if you are not thinking about the cat’s biological sex, the noun itself is grammatically feminine.

مي means water in Levantine Arabic. It is very common in everyday speech.

In Modern Standard Arabic, the usual word is:

• ماء

So:

• مي = colloquial Levantine
• ماء = formal / standard

A learner will hear مي all the time in the Levant.

In Levantine, it is very natural to say put water for/to the flower/plant instead of using a separate verb like water in English.

So:

• تحط مي للزهرة literally = put water for the flower
• natural meaning = water the flower / plant

This is a very common Arabic way of expressing the idea.

للزهرة is made of:

• لـ = for / to
• الزهرة = the flower

Together: للزهرة = for the flower or to the flower

In this sentence, it gives the idea of giving water to the flower/plant. The spelling changes because لـ + ال combine into لل.

كل يوم means every day, and Arabic allows flexible placement for time expressions.

Here:

• أمي كل يوم بتحط مي للزهرة

is completely natural and emphasizes the regular routine.

You could also hear something like:

• أمي بتحط مي للزهرة كل يوم

Both are natural. The first version brings every day earlier in the sentence.

جنبها means next to her or next to it, depending context.

It is made of:

• جنب = beside / next to
• ها = her / it for a feminine singular noun

In this sentence, -ها could refer to:

• أمي = my mother
• الزهرة = the flower

Both are feminine singular, so the sentence is grammatically ambiguous. Usually the intended meaning is understood from context.

Literally, الزهرة means the flower. But in everyday speech, sentences like this can sometimes sound like English the plant, especially when talking about watering something at home.

So depending on context, a speaker may mean:

• the flower itself
• the flowering plant

A learner should be aware that the everyday meaning can be a little broader than the most literal dictionary meaning.

Because the conjunction و (and) is written attached to the following word in Arabic.

So:

• و + القطة becomes والقطة

This is normal Arabic spelling. Many short particles attach directly to the next word.

It sounds natural and conversational. It has several everyday Levantine features:

• امي as informal writing for أمي
• مي for water
• بـ on the present verbs
• simple spoken-style phrasing like تحط مي للزهرة

So this is the kind of sentence a learner could realistically hear in daily conversation.
