حظي كان سيئ مبارح.

A common Levantine-style pronunciation is:

ḥaẓẓi kān sayyeʔ mbāreḥ

Word by word:

• حظي = ḥaẓẓi
• كان = kān
• سيئ = sayyeʔ or sometimes seyyiʔ
• مبارح = mbāreḥ

A few notes:

• The ح is a strong breathy h sound from the throat.
• The ظ is an emphatic consonant; learners often approximate it at first.
• The last sound in سيئ is a glottal stop: the little break in the middle of uh-oh.

حظي means my luck.

In Arabic, possession is often shown by adding a suffix directly to the noun. Here:

• حظ = luck
• -ي = my

So:

• حظي = my luck

This is very common in Levantine and Arabic in general. Instead of using a separate word for my, Arabic often attaches it to the noun.

كان is the past form of to be.

In Arabic, especially in spoken Levantine:

• in the present, you usually do not say a word for is/am/are
• in the past, you usually do use كان

So:

• حظي سيئ = my luck is bad / my luck bad in Arabic structure
• حظي كان سيئ = my luck was bad

That is why كان appears in this sentence.

For a beginner, it is better to keep كان in a sentence like this.

If you want to clearly say was bad yesterday, كان is the normal way to mark that past meaning:

• حظي كان سيئ مبارح

Without كان, the sentence may sound less standard, less clear, or more like casual speech with something understood from context. Learners should treat كان as the safe, correct choice for past-time descriptions.

Because here سيئ is a predicate adjective, not part of a noun phrase like the bad luck.

In this sentence:

• حظي = the subject
• كان = was
• سيئ = bad

So سيئ is describing the subject after كان, and it stays indefinite.

Compare:

• حظي كان سيئ = my luck was bad
• الحظ السيئ = the bad luck

In the second example, السيئ has الـ because it is directly modifying a definite noun.

That is the normal Arabic pattern here.

In Arabic, descriptive words usually come after the noun they describe. Also, in a sentence with كان, the subject comes first and the description comes after:

• حظي = my luck
• كان = was
• سيئ = bad

So the order is basically: my luck + was + bad

This is normal Arabic word order.

مبارح means yesterday.

In Levantine, you usually use it without a preposition:

• مبارح = yesterday

So:

• حظي كان سيئ مبارح = My luck was bad yesterday

You can also move مبارح around:

• مبارح حظي كان سيئ
• حظي كان سيئ مبارح

Both are natural, though the emphasis can change slightly.

It is understandable, but سيئ can sound a bit more formal or closer to Standard Arabic than some everyday Levantine choices.

Many speakers might say something like:

• حظي كان عاطل مبارح
• حظي ما كان منيح مبارح

These can sound more colloquial in some areas.

Still, حظي كان سيئ مبارح is perfectly understandable and useful for learners. It is not wrong; it just may sound a little less everyday depending on the speaker and region.

The words agree with حظ, which is masculine singular.

So:

• كان is masculine singular
• سيئ is masculine singular

That matches حظي because the core noun is حظ.

If the noun were feminine, the forms would usually change. For example, with a feminine noun you would often get:

• كانت
• a feminine adjective form

So the grammar here is based on the gender and number of the noun being described.

It literally means my luck was bad, but in English the natural meaning is often simply:

I was unlucky yesterday.

Arabic often uses expressions with nouns like luck, mood, health, and so on, where English might prefer an adjective with I. So this is a very normal way to express the idea of being unlucky.

Yes. Levantine allows some flexibility, especially with time words like مبارح.

Common possibilities include:

• حظي كان سيئ مبارح
• مبارح حظي كان سيئ
• حظي مبارح كان سيئ

The meaning stays basically the same, but the focus can shift:

• starting with مبارح highlights the time
• ending with مبارح gives the time as extra information at the end

For learners, حظي كان سيئ مبارح is a very good neutral pattern to use.
