آكل البيض في الصباح.

With full vowel endings, it is:

آكُلُ البَيْضَ في الصَّباحِ

A careful pronunciation is roughly:

ʾākulu al-bayḍa fī aṣ-ṣabāḥi

A few notes:

• آكُلُ = I eat
• البَيْضَ = eggs
• في = in
• الصَّباحِ = the morning

In connected speech, ال in الصباح is not pronounced as al-; it assimilates to ṣ, so you hear aṣ-ṣabāḥ.

Because the verb already tells you the subject.

آكُلُ means I eat all by itself. The I is built into the verb form.

So:

• آكُلُ البيضَ في الصباحِ = I eat eggs in the morning
• أنا آكُلُ البيضَ في الصباحِ = also correct, but أنا adds emphasis, contrast, or clarity

Arabic often leaves subject pronouns out when the verb already makes the subject clear.

It is the imperfect form, which often covers:

• the present: I eat
• a habitual action: I eat regularly
• sometimes the near present / ongoing sense, depending on context

In this sentence, the most natural reading is habitual:

I eat eggs in the morning

If you wanted the future, you would usually add سـ or سوف:

• سآكل البيض في الصباح = I will eat eggs in the morning
• سوف آكل البيض في الصباح = same meaning, slightly more formal/full

This comes from how the first-person imperfect is formed.

The verb root is أكل = to eat.
The first-person imperfect is historically أَأْكُلُ.

Because two hamzas come together at the beginning, Arabic spelling normally contracts them into آ.

So:

• underlying form: أأكل
• written form: آكل

That is why you see آكل instead of أأكل.

In Arabic, the definite article الـ is often used for generic meaning.

So البيض can mean:

• eggs in general
• not necessarily the specific eggs in front of us

This is different from English, where a bare plural often sounds more natural for general statements.

So Arabic commonly says:

• آكل البيض في الصباح
  literally something like I eat the eggs in the morning, but naturally meaning I eat eggs in the morning

Here البيض means eggs and is commonly used as a collective noun.

Useful forms:

• بيضة = an egg
• بيض = eggs / egg(s) as a collective
• بيضات = a regular plural form that exists, but بيض is very common

So for a general statement like I eat eggs, البيض is very natural.

Also note that بيض can mean other things in other contexts, but after eat, the meaning eggs is the obvious one.

With full case/mood endings, the sentence is:

آكُلُ البَيْضَ في الصَّباحِ

Here is what is happening:

• آكُلُ ends in ـُ because it is an imperfect verb in the indicative
• البَيْضَ ends in ـَ because it is the direct object of the verb, so it is accusative
• الصَّباحِ ends in ـِ because it comes after the preposition في, so it is genitive

So the structure is:

• verb: آكُلُ
• object: البَيْضَ
• prepositional phrase: في الصَّباحِ

In normal unvocalized writing, these short vowels are usually not written.

Yes, both are possible, but they work a little differently.

• في الصباح = in the morning
• صباحًا = in the morning / mornings, using an adverbial accusative expression

So you can say:

• آكل البيض في الصباح
• آكل البيض صباحًا

Both are natural.
في الصباح is very transparent for learners because it is literally in the morning.

Because Arabic letters are divided into sun letters and moon letters.

• ص in الصباح is a sun letter, so the l of ال assimilates:

  • written: الصباح
  • pronounced: aṣ-ṣabāḥ

• ب in البيض is a moon letter, so the l is pronounced normally:

  • written and pronounced: al-bayḍ

So:

• البيض → al-bayḍ
• الصباح → aṣ-ṣabāḥ

The spelling stays the same even when the pronunciation changes.

Yes. Arabic word order is flexible, though some orders are more neutral than others.

The original sentence:

• آكل البيض في الصباح
  is a very natural way to say it.

You could also say:

• أنا آكل البيض في الصباح
  This adds the pronoun أنا, often for emphasis.

Or:

• في الصباح آكل البيض
  This puts extra focus on in the morning.

So the order can shift depending on what you want to emphasize, but the original sentence is perfectly normal.

In unvocalized Arabic writing, some forms can look identical.

آكل can represent:

• آكُلُ = I eat
• آكِل = eating / eater

In this sentence, context makes I eat the correct reading:

• it begins the sentence like a finite verb
• it is followed by a direct object, البيض
• the whole sentence reads naturally as a complete statement

So although the spelling can look ambiguous without vowels, the grammar here clearly points to I eat.
