המועדון נפתח בבוקר.

A common transliteration is ha-mo'adon niftaḥ ba-boker.

A few pronunciation notes:

• המועדון = ha-mo'adon
• נפתח = niftaḥ
• בבוקר = ba-boker

The last sound in נפתח is ח, a throaty sound that does not exist in standard English.

ה־ is the Hebrew definite article, meaning the.

So:

• מועדון = club
• המועדון = the club

Because מועדון is a masculine singular noun, and the verb form here matches that.

Compare:

• המועדון נפתח = the club opens / was opened
• החנות נפתחה = the store opens / was opened
  because חנות is feminine singular
• המועדונים נפתחו = the clubs open / were opened
  because מועדונים is plural

It comes from the root פ־ת־ח, related to opening.

The form נפתח is from the Nif'al pattern, which often gives a passive or intransitive sense.

That means it can mean something like:

• opened
• was opened
• opens

It focuses on the club undergoing the action, rather than on a person actively opening it.

In unpointed Hebrew, נפתח can be understood as either:

• present: opens / is opened
• past: opened / was opened

Context tells you which meaning is intended. In a general statement with בבוקר, a present-time habitual meaning such as opens in the morning is very natural.

Because the preposition ב־ means in / at, and when it combines with the definite article ה־, the two usually merge.

So:

• ב + ה + בוקר becomes בבוקר

This is pronounced ba-boker, and it means in the morning.

Hebrew often uses the definite form with parts of the day.

For example:

• בבוקר = in the morning
• בערב = in the evening
• בלילה = at night / in the night

So this is a normal Hebrew pattern, not something special about this sentence.

These two forms are related but not the same.

• נפתח = opens / is opened
  This describes the action or event of opening.
• פתוח = open
  This describes the state of already being open.

So:

• המועדון נפתח בבוקר = the club opens in the morning
• המועדון פתוח בבוקר = the club is open in the morning

That is an important distinction.

פותח is usually the active form opens / is opening.

Compare:

• המנהל פותח את המועדון בבוקר = the manager opens the club in the morning
• המועדון נפתח בבוקר = the club opens / is opened in the morning

So פותח emphasizes the doer of the action, while נפתח focuses on what happens to the club.

Because את marks a definite direct object, and this sentence does not have one.

Here, המועדון is the subject of the sentence, not the object.

Compare:

• המועדון נפתח בבוקר = the club opens in the morning
  no direct object
• הוא פותח את המועדון בבוקר = he opens the club in the morning
  here את המועדון is the direct object

Yes. Hebrew word order is somewhat flexible.

The sentence המועדון נפתח בבוקר is a normal neutral order.

But you could also say:

• בבוקר המועדון נפתח

That puts more emphasis on in the morning. The core meaning stays the same.

The root is פ־ת־ח.

This root appears in several related words:

• פתח = opened
• פותח = opens / opening
• נפתח = opens / was opened
• פתוח = open
• פתיחה = opening

Learning the root helps you recognize related vocabulary much more easily.
