החדר הזה מתאים לפגישה, כי הוא שקט.

In Hebrew, this/that usually comes after the noun:

• החדר הזה = this room
• הספר ההוא = that book

So the normal pattern is:

• noun + demonstrative

Also, the noun is usually definite, so you normally say החדר הזה rather than just חדר הזה.

In present-tense Hebrew, a separate word for is/am/are is usually not used.

So:

• החדר הזה מתאים לפגישה literally looks like this room suitable for a meeting
• but it means This room is suitable for a meeting

And:

• הוא שקט literally looks like it/he quiet
• but it means it/he is quiet

This is very normal in Hebrew. In the past or future, Hebrew does use forms of to be, but in the present it usually does not.

מתאים means suitable, appropriate, or fits/is good for.

In sentences like this, learners often experience it as something between an adjective and a verb. Grammatically, it is often treated like an adjective or participle, and it agrees with the noun it describes.

Here:

• החדר is masculine singular
• so we get מתאים

Compare:

• חדר מתאים = a suitable room
• דירה מתאימה = a suitable apartment

So in this sentence, מתאים is describing the room as being suitable.

Because מתאים normally goes with the preposition ל־, which often means for in English in this kind of sentence.

So:

• מתאים ל... = suitable for...
• מתאים לי = suitable for me / suits me
• מתאים לעבודה = suitable for work
• מתאים לפגישה = suitable for a meeting

Even though ל־ often means to, with מתאים it is best learned as part of the expression מתאים ל־.

Because פגישה is not the direct object here.

The word את marks a definite direct object, but here פגישה comes after the preposition ל־:

• מתאים לפגישה = suitable for a meeting

Since ל־ is already a preposition, you do not use את.

Because שקט describes החדר, and חדר is a masculine singular noun.

Hebrew adjectives agree with the noun in gender and number:

• masculine singular: שקט
• feminine singular: שקטה
• masculine plural: שקטים
• feminine plural: שקטות

So:

• החדר שקט = the room is quiet
• הדירה שקטה = the apartment is quiet

Yes, הוא can mean he, but it can also mean it for a masculine noun.

Since חדר is masculine, Hebrew refers back to it with הוא:

• החדר... כי הוא שקט = the room... because it is quiet

So in Hebrew, the same pronoun can mean either he or it, depending on what noun it refers to.

Here כי means because.

So:

• כי הוא שקט = because it is quiet

Be aware that כי can also mean that in other contexts, but in this sentence the meaning is clearly because.

Because החדר הזה is a specific room: this room.

But לפגישה here means for a meeting, not for the meeting, so פגישה is indefinite.

Compare:

• החדר הזה מתאים לפגישה = this room is suitable for a meeting
• החדר הזה מתאים לפגישה החשובה = this room is suitable for the important meeting

So the room is definite, but the meeting is not necessarily definite.

Yes, this word order is completely natural.

The sentence is built like this:

• החדר הזה = this room
• מתאים לפגישה = is suitable for a meeting
• כי הוא שקט = because it is quiet

A very literal structure would be:

• This room suitable for a meeting, because it quiet

which is normal Hebrew syntax once you remember that present-tense is is usually omitted.

A common pronunciation is:

ha-khé-der ha-zé mat-ÍM le-fgi-SHÁ, ki hu sha-KÉT

A rough word-by-word guide:

• החדר = ha-khé-der
• הזה = ha-zé
• מתאים = mat-ím
• לפגישה = le-fgi-shá
• כי = ki
• הוא = hu
• שקט = sha-ket

The stress is usually near the end in:

• מתאים
• לפגישה

and on the last syllable in הזה.

Sometimes, but quiet is the better everyday translation here.

• שקט often means quiet, calm, or not noisy
• in this sentence, it means the room is quiet enough for a meeting

So because it is quiet sounds most natural in English.
