الموسم بلش اليوم.

A common Levantine pronunciation is:

il-mōsem ballaš il-yōm

You may also hear slight regional differences, such as:

• el-mōsem ballaš il-yōm
• il-mawsem ballaš il-yōm

A few helpful notes:

• الموسم = il-mōsem / il-mawsem
• بلش = ballaš
• اليوم = il-yōm

The stress is usually something like:

il-MO-sem ba-LLASH il-YOM

بلش means started or began.

In Levantine, بلّش / بلش is the everyday colloquial verb for to start / to begin.

So:

• بلش الموسم = the season started
• بلش الفيلم = the movie started
• بلشت الشغل = I started the work / I started working

It is very common in spoken Levantine.

No, بلش is colloquial, not Modern Standard Arabic.

In MSA, you would more likely say:

• بدأ الموسم اليوم
• or ابتدأ الموسم اليوم

So this sentence is clearly spoken Levantine Arabic, which is why بلش appears instead of the more formal بدأ.

Here, بلش is the past tense, 3rd person masculine singular.

That means it matches a subject like:

• هو = he
• or any masculine singular noun, such as الموسم

So literally, it is something like:

• the season started

Because الموسم is grammatically masculine singular, بلش is the correct form.

الموسم means the season, while موسم means a season / season depending on context.

Since the English meaning is definite, the Arabic uses الـ:

• موسم = a season
• الموسم = the season

So الموسم بلش اليوم means the season started today, not a season started today.

In Levantine Arabic, subject + verb + time is very normal and common in everyday speech.

So:

• الموسم بلش اليوم = The season started today

You could also hear:

• بلش الموسم اليوم

Both are possible. The difference is mostly about style and emphasis:

• الموسم بلش اليوم puts focus a bit more on the season
• بلش الموسم اليوم starts with the action started

In spoken Levantine, subject-first order is extremely common.

Yes. Arabic word order is fairly flexible, especially in speech.

You might hear:

• الموسم بلش اليوم
• اليوم بلش الموسم
• بلش الموسم اليوم

These all communicate roughly the same basic idea, but the emphasis changes:

• الموسم بلش اليوم = focus on the season
• اليوم بلش الموسم = focus on today
• بلش الموسم اليوم = focus on the action starting

So the version you were given is natural, but not the only possible one.

It can correspond to either one in English, depending on context.

Arabic uses the simple past here:

• بلش = started

But when translating into natural English, you may choose:

• The season started today
• The season has started today

In many contexts, English prefers the simple past with today, but Arabic does not make the same past-vs-present-perfect distinction in the same way.

So the Arabic form itself is normal and flexible.

Because this sentence does not need one.

The main verb here is بلش = started. So the sentence already has its verb.

Arabic only omits a present-tense is/are in sentences like:

• الموسم جديد = The season is new

But in your sentence, the verb is already there:

• الموسم بلش اليوم = The season started today

So there is no missing is.

الموسم is grammatically masculine.

Yes, that matters because the verb agrees with it.

That is why you get:

• الموسم بلش = masculine singular

If the subject were feminine singular, the past verb would usually change. For example:

• الحفلة بلشت اليوم = The party started today

So the form بلش matches الموسم correctly.

In Modern Standard Arabic, the most natural equivalent would be:

• بدأ الموسم اليوم

You might also see:

• ابتدأ الموسم اليوم

Compared with the Levantine sentence:

• الموسم بلش اليوم

Main differences:

• بلش is colloquial Levantine
• بدأ is standard/formal
• Levantine often uses more conversational word order and pronunciation

So this sentence is a good example of how spoken Levantine differs from MSA while still being easy to understand.

Yes. In both words, the ل of الـ is pronounced normally:

• الموسم → il-mōsem
• اليوم → il-yōm

That is because م and ي are not sun letters here, so the l sound does not disappear.

Compare that with a word like:

• الشمس → pronounced more like ish-shams

But in your sentence:

• الموسم بلش اليوم
• the l in الـ stays audible in both nouns.
