אף על פי שההריסה הסתיימה, יש אבק בנייה בחדר.

אף על פי ש is a fixed expression meaning although, even though, or despite the fact that.

It introduces a full clause:

• אף על פי שההריסה הסתיימה = Although the demolition has ended / Even though the demolition ended

A useful comparison:

• אף על פי ש... = followed by a clause
• למרות... = often followed by a noun
• למרות ש... = also possible with a clause in modern Hebrew

So this sentence could also be phrased with למרות ש, but אף על פי ש is a very standard and slightly more formal-looking connector.

In Hebrew, ש is a short attached word meaning that (or introducing a subordinate clause). It is usually written directly onto the following word.

So:

• ש + ההריסה becomes שההריסה

This is completely normal Hebrew spelling. The ש is not a separate word here.

In this sentence:

• אף על פי ש = although
• then the clause begins with ההריסה

So the full written form is:

• אף על פי שההריסה...

הריסה is the noun demolition or destruction. It is a feminine singular noun.

The initial ה is the definite article, meaning the:

• הריסה = demolition
• ההריסה = the demolition

So ההריסה means the demolition.

Hebrew often uses the definite article where English would too, but sometimes Hebrew is even a bit more likely than English to make nouns definite when the situation is specific and known from context.

Because it agrees with its subject, ההריסה, which is feminine singular.

The verb comes from להסתיים, meaning to end, to be completed, or to come to an end.

Past tense forms include:

• הסתיים = he/it ended (masculine)
• הסתיימה = she/it ended (feminine)

Since הריסה is a feminine noun, Hebrew uses:

• ההריסה הסתיימה = the demolition ended / was completed

This kind of agreement is very important in Hebrew, especially in the past tense.

Both are possible in many contexts, but they are not exactly identical in feel.

• הסתיימה = was completed / came to an end
• נגמרה = finished / was over

In this sentence, הסתיימה sounds natural and a bit more neutral or formal for an event/process like a demolition.
נגמרה would also be understandable, but הסתיימה fits very well with something procedural or event-like.

So:

• ההריסה הסתיימה sounds very natural
• ההריסה נגמרה is also possible, just slightly different in tone

יש is the standard Hebrew word for there is / there are.

So:

• יש אבק בנייה בחדר = There is construction dust in the room

In present-tense Hebrew, existential sentences usually use יש rather than a form of to be.

English says:

• There is dust in the room

Hebrew says:

• יש אבק בחדר

This is one of the most common basic sentence patterns in Hebrew.

This is a noun + noun construction called סמיכות (often called the construct state in English grammar books).

It works like this:

• אבק = dust
• בנייה = construction / building

Together:

• אבק בנייה = construction dust

The second noun tells you what kind of dust it is.

Other similar examples:

• כוס מים = a cup of water
• חדר שינה = bedroom
• אתר בנייה = construction site

So אבק בנייה is a very natural Hebrew way to say construction dust.

Hebrew usually prefers the shorter construct-state pattern for this kind of meaning.

So:

• אבק בנייה = the normal, compact way to say construction dust
• אבק של בנייה is grammatically possible, but it sounds less natural here

The של structure is more common when the relationship is less fixed or when you want a more explicit of phrase. But for common category-type combinations, Hebrew often prefers סמיכות.

So a learner should get used to patterns like:

• אבק בנייה
• פועל בניין
• חומר ניקוי

That word order is very natural in Hebrew existential sentences.

The pattern is often:

• יש + thing + place

So:

• יש אבק בנייה בחדר = There is construction dust in the room

This sounds normal and neutral.

Hebrew word order is somewhat flexible, so you could move parts around for emphasis, but the version here is the most straightforward:

• connector clause first
• then יש
• then what exists
• then where it is

A simple pronunciation guide is:

af al pi sheh-ha-harisa histayma, yesh avak bniya ba-cheder

A few notes:

• אף על פי ש = af al pi she-
• ההריסה begins with the article ה, so after ש you get a sequence like sheh-ha-
• הסתיימה is roughly his-tay-MA
• בחדר is ba-CHE-der, with the stress on the second syllable

If you want to sound natural, try saying it in two chunks:

• אף על פי שההריסה הסתיימה,
• יש אבק בנייה בחדר.
