Kannst du bitte den Tisch decken?

Because this is a yes/no question in German. In main-clause yes/no questions, the conjugated verb comes first.

• Statement: Du kannst bitte den Tisch decken.
• Question: Kannst du bitte den Tisch decken?

So the pattern is:

conjugated verb + subject + other elements + infinitive

That is why Kannst comes before du.

Because kannst is a modal verb. When German uses a modal verb such as können, müssen, wollen, or sollen, the second verb usually goes to the end of the clause in the infinitive form.

Here:

• kannst = the conjugated modal verb
• decken = the main verb in the infinitive

So the structure is:

Kannst + du + bitte + den Tisch + decken

This is very normal German word order with modal verbs.

Because den Tisch is the direct object of the verb decken, and direct objects usually take the accusative case in German.

Tisch is a masculine noun:

• nominative: der Tisch
• accusative: den Tisch

So:

• der Tisch = the table as the subject
• den Tisch = the table as the object

In this sentence, someone is doing something to the table, so it must be den Tisch.

In this expression, den Tisch decken means to set the table.

The verb decken more literally has meanings like to cover. Historically, the idea is related to covering the table, for example with a tablecloth or with the things needed for a meal. In modern everyday German, den Tisch decken is just the normal idiom for setting the table.

So you should learn den Tisch decken as a fixed, common expression.

Not necessarily. In German, just like in English, Can you ... ? is often used as a polite request, not a literal question about ability.

So Kannst du bitte den Tisch decken? usually means:

• Can you please set the table?
• and functionally, it often means Please set the table

It sounds softer and less direct than a plain command.

Yes. A more direct command would be:

• Deck bitte den Tisch!

That is the imperative form for du.

Compared with:

• Kannst du bitte den Tisch decken? = softer, more polite request
• Deck bitte den Tisch! = more direct instruction

Both are common, but the version with kannst du often sounds friendlier.

Bitte adds politeness. Here it works like please in English.

So:

• Kannst du den Tisch decken? = Can you set the table?
• Kannst du bitte den Tisch decken? = Can you please set the table?

It makes the request sound more courteous.

Yes, bitte is somewhat flexible in German, though some positions sound more natural than others.

These are possible:

• Kannst du bitte den Tisch decken?
• Kannst du den Tisch bitte decken?

Both are natural. The first one is probably the most neutral and common.

If you are learning, Kannst du bitte ... ? is a very safe pattern to use.

Du is the informal singular word for you. It is used with:

• family
• friends
• children
• people you know well

If you wanted the formal version, you would say:

• Können Sie bitte den Tisch decken?

So the sentence with du suggests an informal situation.

Because the verb können is irregular. In the singular present tense, the vowel changes from ö to a in some forms:

• ich kann
• du kannst
• er/sie/es kann

But in the plural it stays with ö:

• wir können
• ihr könnt
• sie/Sie können

So kannst du is the correct form.

Yes, it matches very closely in both structure and tone.

• Kannst du ... ? = Can you ... ?
• bitte = please
• den Tisch decken = set the table

The important thing to remember is that, in both languages, this kind of sentence is usually understood as a request, not a real question about whether the person has the physical ability to do it.

A simple learner-friendly pronunciation guide is:

KAHNST doo BIT-tuh den tish DEK-ken

A few points:

• kannst: the a is short, like in cut for many English speakers, but not exactly the same
• du: sounds like doo
• bitte: two syllables, BIT-tuh
• Tisch: rhymes roughly with English ish, but with a t at the start
• decken: DEK-ken, with a clear k

Also, German usually stresses:

• KANNST
• BITte
• TISCH
• DEcken

depending on the speaker and context.

It can include whatever is needed to prepare the table for a meal, depending on context. That might include:

• plates
• cutlery
• glasses
• napkins
• maybe a tablecloth

So den Tisch decken is broader than just placing one object on the table. It means preparing the table properly for eating.
