أصبح العمل سهلا.

Here أصبح means became.

In this sentence, it is not mainly about morning, even though the verb is historically related to morning. In Modern Standard Arabic, أصبح is very commonly used like صار to mean to become:

• أصبح الجو باردًا = The weather became cold.
• أصبحت المدينة مزدحمة = The city became crowded.

So:

• أصبح العمل سهلا = The work became easy.

Because this is a verbal sentence in Arabic.

Arabic often allows two major sentence types:

• Nominal sentence: starts with a noun
• Verbal sentence: starts with a verb

Since أصبح comes first, this is a verbal sentence:

• أصبح = verb
• العمل = the thing that became something
• سهلا = what it became

A very literal breakdown is:

• أصبح = became
• العمل = the work
• سهلا = easy

So Arabic word order here is perfectly normal.

العمل is the subject of أصبح, traditionally called اسم أصبح.

Verbs like كان، أصبح، صار، أمسى are often taught together because they behave similarly:

• their subject is in the nominative
• their predicate/complement is in the accusative

So in:

• أصبح العمل سهلا

we have:

• أصبح = verb
• العملُ = subject of أصبح (nominative)
• سهلًا = predicate/complement of أصبح (accusative)

If full case endings were written, it would be:

• أصبح العملُ سهلًا

Because it is the predicate/complement of أصبح, called خبر أصبح.

With أصبح and similar verbs, Arabic grammar works like this:

• اسم أصبح stays nominative
• خبر أصبح becomes accusative

So:

• العملُ = nominative
• سهلًا = accusative

That is why you see سهلا and not سهلٌ here.

This is one of the most important patterns to learn with the كان and sisters group.

Because العمل is definite, while سهلا is indefinite.

• العمل has الـ, so it means the work
• سهلا has no الـ, so it is indefinite: easy

In Arabic:

• definite nouns do not take tanwīn
• indefinite nouns usually do take tanwīn

So:

• العملُ = definite, no tanwīn
• سهلًا = indefinite, with tanwīn fatḥ

This is very normal in predicate structures like this.

Because after أصبح, the predicate is often an indefinite adjective or noun describing a resulting state.

Compare in English:

• The work became easy not
• The work became the easy

Arabic works similarly here:

• العمل = the work
• سهلًا = easy

So the mismatch is expected:

• subject: definite
• predicate: often indefinite

That is completely correct Arabic.

It is an adjective in form, but grammatically it functions as the predicate/complement of the sentence.

The word سهل means easy. In this sentence it describes the state of العمل:

• العملُ سهلٌ = The work is easy.
• أصبح العملُ سهلًا = The work became easy.

So you can think of it as:

• an adjective meaning easy
• used as the predicate of أصبح

Because the subject العمل is singular.

• العمل = the work
• it is singular masculine
• so the verb is 3rd person masculine singular

That gives:

• أصبح العملُ سهلًا

If the subject were feminine singular, you would get:

• أصبحت المهمة سهلةً = The task became easy.

If the subject were plural, the form would change accordingly.

A careful full pronunciation is:

• aṣbaḥa al-ʿamalu sahlan

In connected speech, the ال after the verb is often linked smoothly, so it may sound closer to:

• aṣbaḥal-ʿamalu sahlan

A few pronunciation notes:

• أ at the beginning of أصبح is a pronounced hamza
• ص is an emphatic s
• ع in العمل is the deep throat sound ʿayn
• ح in أصبح is the breathy ḥ

Not always.

It can also have a more literal connection to morning, depending on context. But in many standard sentences like this one, it simply means became.

So learners should often read it in one of two ways:

1. entered the morning / came to be in the morning
2. became

In your sentence, the natural interpretation is clearly:

• became

Yes, in this sentence you usually can.

• أصبح العمل سهلا
• صار العمل سهلا

Both can mean The work became easy.

However, there can be slight stylistic or contextual differences:

• صار is a very common general verb for became
• أصبح can sometimes sound a bit more formal or literary, and in some contexts it may also carry its original link to morning

But in many textbook-style sentences, both are acceptable.

Without أصبح, you get a simple nominal sentence:

• العمل سهل = The work is easy.

With أصبح, the meaning changes to a change of state:

• أصبح العمل سهلا = The work became easy.

So أصبح adds the idea of transition or change, not just description.

Because in most real-world Arabic writing, short vowels and case endings are omitted.

So you often see:

• أصبح العمل سهلا

instead of the fully vowelled form:

• أصبحَ العملُ سهلًا

Arabic readers usually recover the grammar from context.

For learners, though, it helps to know the full grammatical form:

• أصبحَ = verb
• العملُ = nominative subject
• سهلًا = accusative predicate

Yes.

أصبح is one of the verbs commonly taught with كان وأخواتها.

These verbs typically do this:

• take a subject in the nominative
• make the predicate accusative

So this sentence is a classic example:

• أصبحَ العملُ سهلًا

That makes it a very useful model sentence for this grammar pattern.
