Der Sturm hat das Dach beschädigt.

Sturm is a masculine noun, so its basic dictionary form is der Sturm.

In this sentence, der Sturm is also the subject of the sentence, so it is in the nominative case:

• der Sturm = the storm

If it were a direct object, you would usually see den Sturm instead.

Dach is a neuter noun, so its article is das:

• das Dach = the roof

In this sentence, das Dach is the direct object, the thing affected by the action.

For neuter nouns, the article das stays the same in both nominative and accusative, so:

• nominative: das Dach
• accusative: das Dach

That is why it does not change here.

The sentence breaks down like this:

• Der Sturm → nominative (the subject, doing the action)
• das Dach → accusative (the direct object, receiving the action)

So the structure is:

Subject + helping verb + object + past participle

This sentence is in the present perfect tense (Perfekt) in German.

German often forms the perfect tense with:

• a form of haben or sein
• plus a past participle

Here:

• hat = from haben
• beschädigt = past participle of beschädigen

So:

• hat beschädigt = has damaged / damaged

In everyday spoken German, the Perfekt is very common for talking about past events.

German perfect tense uses either haben or sein as the auxiliary verb.

You usually use haben with:

• most verbs
• especially verbs that take a direct object

Since beschädigen takes a direct object here (das Dach), it uses haben:

• Der Sturm hat das Dach beschädigt.

You would use sein mainly with verbs of movement or change of state, such as:

• Er ist gegangen.
• Das Kind ist eingeschlafen.

In a normal German main clause, the finite verb goes in second position.

Here, the finite verb is:

• hat

The past participle:

• beschädigt

goes to the end of the clause.

So the sentence pattern is:

• Der Sturm | hat | das Dach | beschädigt

This is a very common German word order pattern with two-part verbs in the perfect tense.

In this sentence, beschädigt is a past participle, part of the verb phrase:

• hat beschädigt = has damaged

But beschädigt can also sometimes be used like an adjective in other contexts:

• ein beschädigtes Dach = a damaged roof

So the form is the same, but the function depends on the sentence.

Yes. That is the simple past (Präteritum) form.

• Der Sturm hat das Dach beschädigt. → present perfect
• Der Sturm beschädigte das Dach. → simple past

Both can mean The storm damaged the roof.

The difference is mostly about style and usage:

• Perfekt is very common in spoken German
• Präteritum is more common in writing, storytelling, and formal narration

Grammatically, it is the German present perfect, so a very literal translation is:

• has damaged

But in normal English, depending on context, you often translate it simply as:

• damaged

So German Perfekt does not always match English has damaged exactly in usage. Very often it is just the normal way to talk about the past in conversation.

In German, all nouns are capitalized.

So:

• der Sturm
• das Dach

This is different from English, where common nouns are normally lowercase.

A rough pronunciation guide is:

be-SHAY-digt

A bit more closely:

• be as in a short unstressed buh
• schä sounds a bit like shay
• digt ends with a short igt sound

A few helpful points:

• sch is pronounced like English sh
• ä is somewhat like the vowel in air, depending on accent
• the final g in some accents may sound a bit softer, sometimes almost like k at the end

You do not pronounce it like English be-skad-igd.

Yes, German word order can change for emphasis, as long as the verb rules are respected.

For example:

• Das Dach hat der Sturm beschädigt.

This still means the same basic thing, but now das Dach is emphasized first.

What stays important is:

• the finite verb (hat) remains in second position
• the past participle (beschädigt) remains at the end

The dictionary form is beschädigen, which means to damage.

The main forms are:

• infinitive: beschädigen
• 3rd person singular present: beschädigt
• past participle: beschädigt

So in this sentence, the participle happens to look the same as the present-tense form, but they are functioning differently:

• Er beschädigt das Dach. = present tense
• Er hat das Dach beschädigt. = perfect tense

Not exactly.

• beschädigen = to damage
• zerstören = to destroy

So:

• Der Sturm hat das Dach beschädigt. means the roof was harmed, but not necessarily completely ruined.
• If you said Der Sturm hat das Dach zerstört, that would mean the roof was destroyed.

So beschädigen is usually less extreme than zerstören.
