المئزر نظيف اليوم.

In Modern Standard Arabic, the verb to be is usually omitted in the present tense.

So:

• المئزر نظيف اليوم = The apron is clean today

Arabic often says this as a nominal sentence:

• المئزر = the apron
• نظيف = clean
• اليوم = today

If you wanted was or will be, then Arabic would use a verb:

• كان المئزر نظيفًا = The apron was clean
• سيكون المئزر نظيفًا = The apron will be clean

الـ is the Arabic definite article, meaning the.

So:

• مئزر = an apron
• المئزر = the apron

In this sentence, the noun is definite, which is very common for the topic or subject of a nominal sentence.

Because نظيف here is the predicate, not an attributive adjective inside a noun phrase.

There is an important difference:

• المئزر نظيف = The apron is clean
• المئزر النظيف = the clean apron

In the first sentence, نظيف is telling us something about المئزر, so it stays indefinite.

In the second phrase, النظيف is directly modifying the noun inside one noun phrase, so it must match it in definiteness.

This is a nominal sentence in Arabic.

Its structure is:

• المئزر = the subject/topic, called مبتدأ
• نظيف = the predicate/comment, called خبر
• اليوم = an adverb of time, meaning today

So the pattern is basically:

• [noun/topic] + [description] + [time expression]

المئزر is masculine, so the adjective appears in the masculine singular form:

• نظيف

If the noun were feminine, the adjective would usually take ـة:

• المريلة نظيفة اليوم = The apron is clean today

So the sentence shows normal gender agreement:

• masculine noun → masculine adjective

It is commonly pronounced roughly as al-miʾ-zar.

A few helpful notes:

• الـ = al-
• مِ = mi
• ئ represents a hamza, a small glottal stop
• زر = zar

So there is a slight catch in the throat between mi and zar.

The fully vowelled form is usually written:

• المِئْزَر

The hamza, written here as ئ, represents a glottal stop.

That means the word is not pronounced as one smooth mizar. Instead, there is a small break:

• miʾzar

For English speakers, this can feel like a tiny pause or catch in the throat.

It is a real consonant in Arabic, so it should not be ignored.

In Arabic, اليوم can mean today depending on context.

So in a sentence like this:

• المئزر نظيف اليوم

the natural meaning is:

• The apron is clean today

This is very common with time words in Arabic. Even though اليوم literally contains الـ, it often functions as the normal word for today.

Yes, Arabic word order is fairly flexible, especially with adverbs like اليوم.

All of these are possible, with slightly different emphasis:

• المئزر نظيف اليوم
• المئزر اليوم نظيف
• اليوم المئزر نظيف

The original version is very natural and straightforward. Putting اليوم first can emphasize the time more, like Today, the apron is clean.

In fully vowelled MSA, it would normally be:

• المِئْزَرُ نَظيفٌ اليَوْمَ

Here is why:

• المئزرُ ends in ـُ because it is the subject/topic of the nominal sentence
• نظيفٌ ends in ـٌ because it is the predicate
• اليومَ ends in ـَ because it functions as an adverbial expression of time

In normal everyday writing, these short vowels are usually omitted, so you will often just see:

• المئزر نظيف اليوم

It is a valid MSA word, but learners should know that vocabulary can vary by region and register.

مئزر can refer to an apron or a waist-wrap type garment in formal Arabic. In everyday speech, many speakers may use other words depending on the country, such as مريلة.

So for MSA, المئزر is fine, but in real-life conversation you may hear alternatives.

A common way is to use ليس:

• المئزر ليس نظيفًا اليوم = The apron is not clean today

Notice that:

• ليس acts a bit like is not
• نظيفًا takes a different ending after ليس

So the positive sentence:

• المئزر نظيف اليوم

becomes:

• المئزر ليس نظيفًا اليوم
