اشتريت دوا على وجع راس امي.

اشتريت means I bought.

The -ت at the end marks first person singular in the past tense, so it tells you the subject is I.

A very rough breakdown is:

• اشترى = he bought
• اشتريت = I bought

In Levantine pronunciation, you’ll often hear it as something like ishterēt or ishtarēt, depending on the speaker and region.

دوا is the common colloquial Levantine form for medicine.

In Modern Standard Arabic, the word is usually دواء. In everyday Levantine speech, that final hamza is often dropped in pronunciation and spelling, so learners commonly see:

• دواء = MSA
• دوا = Levantine / everyday writing

So this sentence is clearly in a spoken, dialect-style register rather than formal Standard Arabic.

Yes, على literally often means on, but in colloquial Arabic it can also be used in expressions where English would use for.

Here, دوا على وجع راس means medicine for a headache or more literally medicine against headache pain.

So in this sentence:

• دوا = medicine
• على وجع راس = for headache / against headache pain

This is very natural in Levantine. English learners often expect a one-to-one match like على = on, but prepositions rarely match perfectly across languages.

Literally, وجع راس means pain of head or head pain.

In natural English, that becomes headache.

Word by word:

• وجع = pain / ache
• راس = head

So وجع راس is a very common everyday way to say headache in Levantine.

This is another difference between everyday dialect writing and Standard Arabic.

In MSA, the word is usually written رأس. In Levantine informal writing, people often write it as راس, reflecting everyday pronunciation and skipping the hamza.

So:

• رأس = formal / MSA spelling
• راس = common colloquial spelling

Both refer to the same word: head.

راس امي literally means my mother’s head.

This is a possessive structure, often called an idafa construction. Arabic commonly shows possession by putting two nouns next to each other:

• راس = head
• أمي / امي = my mother

So:

• راس أمي = my mother’s head

And inside the bigger phrase:

• وجع راس امي = the pain of my mother’s head
• natural English: my mother’s headache

Arabic often expresses ideas more literally than English here.

Because Arabic usually attaches possessive pronouns directly to the noun.

So:

• أم = mother
• أمي = my mother

The -ي ending means my.

That’s why you do not need a separate word for my.

Arabic does not always use definiteness the same way English does.

In a phrase like وجع راس امي, the meaning is understood as a specific problem: my mother’s headache. Because of the possessive relationship, the phrase becomes definite in meaning even without adding الـ everywhere.

Also, colloquial Arabic often uses shorter, looser structures than formal Arabic. A speaker is not trying to build a textbook-style phrase; they are just saying the idea naturally.

So even though English says my mother’s headache, Arabic can simply say وجع راس امي.

A common Levantine-style pronunciation would be roughly:

ishtareet dawa ʿa wajaʿ rās emmi

A few notes:

• على is often reduced in speech to عَ before the next word.
• أمي / امي is often pronounced emmi in Levantine.
• وجع may sound like wajaʿ.

So the sentence may sound more like:

اشتريت دوا عَ وجع راس امي

in fast everyday speech.

It is mainly Levantine / colloquial.

Clues include:

• دوا instead of دواء
• راس instead of رأس
• the overall everyday spoken style
• likely pronunciation of على as عَ

A more Standard Arabic version would be something like:

اشتريت دواءً لصداع أمي or اشتريت دواءً لوجع رأس أمي

But the sentence you gave sounds like something a person would naturally say in everyday Levantine conversation.

Yes. Levantine often allows several natural variants. For example, someone might say:

• اشتريت دوا لوجع راس امي
• اشتريت لأمي دوا لوجع راسها
• جبت دوا لوجع راس امي

These all mean roughly the same thing, though the wording shifts a little:

• اشتريت = I bought
• جبت = I brought / got
• لـ can also mean for
• راسها = her head

So your original sentence is natural, but it is not the only possible way to express the idea.

Because Arabic often prefers a phrase like medicine for headache rather than a compound noun like English headache medicine.

English easily stacks nouns:

• headache medicine

Levantine more naturally uses:

• دوا على وجع راس
• literally: medicine for head pain

So the Arabic structure is different, but the meaning is the same.

Here is a simple breakdown:

• اشتريت = I bought
• دوا = medicine
• على = for / against
• وجع = pain
• راس = head
• امي = my mother

Very literally:
I bought medicine for pain head my-mother

Natural English:
I bought medicine for my mother’s headache.
