هو يحب الطعام في هذا المطعم.

Yes. In Arabic, the verb يحب already tells you the subject is he.

So هو يحب الطعام في هذا المطعم literally includes he twice in a sense:

• هو = he
• يحب = he likes

In MSA, the pronoun هو is often optional here. You could simply say:

يحب الطعام في هذا المطعم

That still means He likes the food in this restaurant.

Using هو can add:

• clarity
• emphasis
• contrast, as in He likes the food, even if someone else does not

يحب is the imperfect (non-past/present) form of the verb أحبَّ / يُحِبُّ, meaning to like or to love depending on context.

Here it is:

• 3rd person
• masculine
• singular

So it means he likes or he loves.

In this sentence, with food, English would usually translate it as likes, not loves.

If fully vowelled, it is:

يُحِبُّ

A common transliteration is yuḥibbu.

It can mean either one. Arabic يحب covers a range that English often splits into like and love.

The exact translation depends on context:

• هو يحب الطعام → usually He likes the food
• هو يحب أسرته → often He loves his family

With food, English usually prefers likes, unless you want strong emphasis such as He loves the food.

Because Arabic often uses the definite article الـ in places where English uses no article at all.

So الطعام can mean:

• the food
• or sometimes simply food, depending on context

In this sentence, الطعام most naturally means the food, especially the food served at that restaurant.

This is very common in Arabic. English and Arabic do not always use definiteness in the same way.

Because ط is a sun letter.

When الـ comes before a sun letter, the l sound assimilates to the next consonant. So:

• written: الطعام
• pronounced: roughly aṭ-ṭaʿām

By contrast, in المطعم, the letter م is a moon letter, so the l is pronounced:

• المطعم → al-maṭʿam

So the spelling stays the same, but the pronunciation changes depending on the next letter.

في literally means in, but in Arabic it is also very commonly used where English would say at for places.

So:

• في هذا المطعم = in this restaurant
• but natural English may say at this restaurant

Both are fine as translations depending on style.

In this sentence, في هذا المطعم gives the location or setting: the food he likes is the food in/at this restaurant.

In standard Arabic, when a demonstrative like هذا means this before a noun, the noun is usually definite, so it keeps الـ:

• هذا المطعم = this restaurant

That is the normal MSA pattern.

If you say هذا مطعم, it usually does not mean this restaurant. It is more likely interpreted as:

• This is a restaurant

So:

• هذا المطعم = this restaurant
• هذا مطعم = this is a restaurant

That is a very common point of confusion for English speakers.

المطعم means the restaurant.

It comes from the root related to food/eating, and in this sentence it is part of the phrase:

هذا المطعم = this restaurant

Because it comes after في, it is the object of a preposition, so in fully vowelled Arabic it would have a genitive ending:

المطعمِ

In normal Arabic writing, that ending is usually not written.

If fully vowelled in careful MSA, the sentence would be:

هُوَ يُحِبُّ الطَّعَامَ فِي هَذَا الْمَطْعَمِ

The important endings are:

• الطعامَ: accusative, because it is the direct object of يحب
• المطعمِ: genitive, because it comes after the preposition في

A learner often sees the sentence without these endings in normal print:

هو يحب الطعام في هذا المطعم

That is completely normal. Everyday Arabic texts usually omit short vowel endings.

Yes. Arabic allows more flexibility than English.

This sentence is in a subject–verb–object style:

• هو = subject
• يحب = verb
• الطعام = object

You could also omit the pronoun and say:

يحب الطعام في هذا المطعم

That is very natural, because the verb already shows the subject is he.

Using هو can make the subject more explicit or emphatic.

In practical meaning, it tells you the setting of the food he likes: the food in this restaurant.

So the sentence means he likes the food that is found/served there.

English sometimes makes this relationship clearer by saying:

• He likes the food in this restaurant
• or He likes the food at this restaurant

If the meaning were He likes this restaurant, Arabic would be different:

هو يحب هذا المطعم

There, هذا المطعم would be the direct object of يحب.

A useful pronunciation guide is:

huwa yuḥibbu aṭ-ṭaʿāma fī hādhā al-maṭʿam

A few notes:

• ḥ = a breathy h sound, from ح
• ṭ = an emphatic t, from ط
• ʿ = the consonant ع, which has no exact English equivalent

Also remember:

• الطعام is pronounced with assimilation: aṭ-ṭaʿām
• المطعم keeps the l sound: al-maṭʿam

If you want a very rough English-style approximation, it is something like:

hoo-wa yoo-HIB-boo at-ta-AA-m fee HAA-tha al-MAT-am

But that rough version does not capture all the real Arabic sounds.
