De zevende week begint.

Because week is a de-word in Dutch: de week.

In Dutch, every noun is either a de-word or a het-word. You usually have to learn the article together with the noun. Time words like de dag, de maand, and de week are all common de-words.

So:

• de week = the week
• de zevende week = the seventh week

Zevende is the ordinal form of zeven.

Compare:

• zeven = seven
• de zevende = the seventh

Dutch ordinals often end in -de or -ste. For zeven, the correct ordinal is zevende.

A few examples:

• vijf → vijfde
• zes → zesde
• zeven → zevende
• acht → achtste

Here zevende is used before a noun, so it acts like an adjective: de zevende week.

In normal Dutch, you usually need the article here: de zevende week.

That is because week is a specific countable noun, and zevende is identifying which one. So Dutch normally uses the definite article:

• de zevende week = the seventh week

Without de, it sounds incomplete in ordinary sentences. You might see article omission in headlines, notes, or very special styles, but for standard Dutch, de zevende week is the correct form.

Because the subject is de zevende week, which is third person singular.

The verb beginnen means to begin. Its present tense forms are:

• ik begin = I begin
• jij begint = you begin
• hij/zij/het begint = he/she/it begins
• wij/jullie/zij beginnen = we/you/they begin

Since de zevende week is singular, Dutch uses begint.

So:

• De zevende week begint. = The seventh week begins.

Because Dutch main clauses usually follow the V2 rule: the finite verb comes in the second position.

In this sentence:

• De zevende week = first position
• begint = second position

So the structure is:

• De zevende week | begint

This is very normal Dutch word order.

You could also move another element to the front, but then the verb still stays second:

• Morgen begint de zevende week.

So the important pattern is not just subject + verb, but more generally first element + finite verb.

Yes, begint can often be translated as both begins and starts.

So this sentence could be understood as:

• The seventh week begins
• The seventh week starts

In many contexts, beginnen and starten are both possible in Dutch, though beginnen is extremely common and natural here.

A simple learner-friendly pronunciation is:

• zevende ≈ ZAY-vun-duh
• begint ≈ buh-GINT

A few pronunciation notes:

• The z in zevende sounds like the z in zoo.
• The first syllable ze- has a long vowel, roughly like zay.
• The g in begint is the Dutch guttural g/ch sound, which can be hard for English speakers.
• The stress in begint is on the second syllable: be-GINT.

You do not need perfect pronunciation right away; getting the stress and rhythm right is already helpful.

Yes, in a way. In Dutch, adjectives and adjective-like words before nouns often take an -e ending, especially after de.

Here, zevende behaves like an adjective before week:

• de zevende week

This -e form is the normal one in this kind of phrase. You do not say de zevend week.

So even though zevende is an ordinal number, it follows the same general pattern you see with adjectives:

• de lange week
• de zevende week

Not if you mean exactly the seventh week begins in normal Dutch.

Week zeven usually means week seven as a label or numbering system, like in schedules, school timetables, sports, or project planning. It is more like naming the week by number than using an ordinal adjective.

So there is a difference:

• de zevende week = the seventh week
• week zeven = week seven

Both can be possible in the right context, but they are not exactly the same style.

Because the sentence is talking about one week: the seventh week.

So Dutch uses the singular:

• de week
• begint

If it were plural, you would need a different phrase and a plural verb:

• De zevende weken beginnen would mean The seventh weeks begin, which normally does not make much sense unless you are comparing multiple series or calendars.

Yes, it is grammatical and natural.

It sounds like something you might see in:

• a schedule
• a course plan
• a book divided into weeks
• a calendar context
• a narrative marking the passage of time

Dutch speakers would understand it immediately as a normal sentence meaning that week number seven is now starting.
