اليوم بالمكتب بلشنا مشروع جديد، وكل واحد عنده مهمة لحاله.

In Levantine Arabic, it is very common to begin a sentence with time and place expressions before the main action.

So:

• اليوم = today
• بالمكتب = in the office
• بلشنا = we started

This order feels very natural in Arabic:

• اليوم بالمكتب بلشنا مشروع جديد
• literally: Today in the office we started a new project

English usually prefers the subject earlier, but Arabic often sets the scene first.

بالمكتب is made of:

• بـ = in / at
• المكتب = the office

Together: بالمكتب = in the office or at the office

The بـ is a very common preposition in Levantine. When it comes before الـ, they join in writing:

• ب + المكتب → بالمكتب

This kind of combination happens a lot in Arabic.

بلشنا is the common Levantine dialect form meaning we started.

It comes from the verb بلّش = to begin / to start.

So:

• بلّش = he started
• بلشنا = we started

By contrast, بدأنا is more Standard Arabic (MSA). A learner will often hear both, but in everyday Levantine conversation, بلشنا sounds much more natural.

It is usually pronounced roughly like ballashna or blashna, depending on the speaker and region.

A helpful breakdown is:

• بلّش = ballash
• بلشنا = ballash-na = we started

The double لّ means the l sound is held slightly longer.

Because Arabic verbs already include the subject inside the verb ending.

In بلشنا, the ending ـنا means we.

So:

• بلشنا = we started

Arabic often does not need an extra subject pronoun unless you want emphasis.

For example:

• نحنا بلشنا = we started with emphasis on we
• بلشنا = normal, natural everyday form

كل واحد literally means every one or each one.

In this sentence, it means everyone / each person.

Breakdown:

• كل = every / all
• واحد = one

So وكل واحد عنده مهمة لحاله means something like:

• and each person has a task of their own

It is a very common everyday way to say everyone in spoken Arabic.

عنده literally means at him, but in Arabic this structure is often used to express having.

Breakdown:

• عند = at / with
• ـه = him / his

So:

• عنده = he has
• more literally: there is at him

In the sentence:

• كل واحد عنده مهمة
• each person has a task

This is one of the most important patterns in Arabic:

• عندي = I have
• عندك = you have
• عنده = he has
• عندها = she has
• عندنا = we have

مهمة commonly means task, assignment, or mission, depending on context.

Here it fits very naturally because the sentence is about a project and each person being assigned something specific.

So:

• مهمة = a task / an assignment

It sounds slightly more like a specific responsibility than a general job.

لحاله means by himself, on his own, or separately.

Breakdown:

• لـ = for / to
• حال = self / state
• ـه = his / him

In everyday Levantine, لحاله often means:

• alone
• by himself
• independently
• on his own

In this sentence, مهمة لحاله means the person has his own separate task.

So the idea is not necessarily physical loneliness, but rather an individual responsibility.

Because كل واحد is grammatically singular.

Even though it refers to multiple people in meaning, the expression itself is built around one person at a time:

• each one

So Arabic uses singular agreement:

• كل واحد عنده
• كل واحد ... لحاله

That is completely normal.

It is similar to English ideas like:

• Each person has their own task

English may use their in modern usage, but Arabic usually stays singular here.

Yes, very often.

For example:

• قاعد لحاله = he is sitting alone
• راح لحاله = he went by himself
• عملها لحاله = he did it on his own

So the exact meaning depends on context. In your sentence, it is closer to:

• each one has an individual task rather than
• each one has a task while being physically alone

و simply means and.

It connects the two parts of the sentence:

1. اليوم بالمكتب بلشنا مشروع جديد
2. وكل واحد عنده مهمة لحاله

So:

• Today at the office we started a new project, and each person has their own task.

In Arabic, و is attached directly to the next word in writing.

Because adjectives normally come after the noun in Arabic.

So:

• مشروع جديد = a new project
• literally: project new

Also, the adjective matches the noun in definiteness, gender, and number.

Here:

• مشروع = masculine singular, indefinite
• جديد = masculine singular, indefinite

That is why they match this way.

Yes. Levantine allows several natural variations. For example:

• اليوم بالمكتب بلشنا مشروع جديد، وكل واحد عنده شغلة لحاله.
• اليوم بالمكتب ابتدينا مشروع جديد، وكل واحد عنده مهمة خاصة فيه.

These have slightly different wording, but the original sentence is natural and idiomatic.

A few notes:

• شغلة can mean thing / piece of work / task
• خاصة فيه means specific to him / his own

So your original sentence is a good, everyday Levantine sentence.
