הפגישה שלנו מתחילה בשבע וחצי.

The ה־ at the beginning is the Hebrew definite article, meaning the.

So:

• פגישה = a meeting / meeting
• הפגישה = the meeting

In this sentence, the speaker is talking about a specific meeting, so הפגישה is natural.

In Hebrew, possessive words like שלי, שלך, שלו, שלנו usually come after the noun.

So:

• הפגישה שלנו = our meeting
• literally: the meeting of ours

This is a very normal Hebrew structure. English puts the possessive before the noun, but Hebrew often puts it after.

שלנו means our / ours.

It comes from של + a pronoun ending:

• שלי = my / mine
• שלך = your / yours
• שלו = his
• שלה = her
• שלנו = our / ours

In הפגישה שלנו, it means our meeting.

Because the subject הפגישה is a feminine singular noun.

In the present tense, Hebrew verbs agree with the subject in gender and number:

• masculine singular: מתחיל
• feminine singular: מתחילה
• masculine plural: מתחילים
• feminine plural: מתחילות

Since פגישה is feminine singular, the correct form is מתחילה.

A lot of Hebrew nouns ending in ־ה are feminine, and פגישה is one of them.

So:

• פגישה טובה = a good meeting
• הפגישה מתחילה = the meeting begins

The feminine form of the adjective and the verb matches the noun.

As always, there are exceptions in Hebrew, but here the ־ה ending is a strong clue.

It is present tense.

The root is related to להתחיל = to begin / to start.

So:

• היא מתחילה = she begins / she is beginning / she begins
• הפגישה מתחילה = the meeting begins / the meeting is starting

Like many Hebrew present-tense forms, מתחילה can sound like simple present in English or sometimes present progressive, depending on context.

The prefix ב־ usually means in / at / on, depending on context.
Here it means at a time.

So:

• בשבע = at seven
• בשמונה = at eight
• בבוקר = in the morning

This prefix attaches directly to the word that follows.

Hebrew often expresses :30 as [hour] and a half.

So:

• שבע וחצי = seven and a half
• idiomatically: seven thirty

That is why בשבע וחצי means at 7:30.

This is very common in everyday Hebrew.

Yes.

• ו־ = and
• חצי = half

So שבע וחצי is literally seven and a half.

Hebrew uses this same pattern with time very naturally:

• שתיים וחצי = 2:30
• חמש וחצי = 5:30

When telling time in Hebrew, the hour is usually treated as if the word שעה (hour) is understood, and שעה is feminine.

So Hebrew normally uses the feminine form of the number in clock time:

• אחת = one
• שתיים = two
• שלוש
• ארבע
• שבע

That is why בשבע is the expected form for at seven.

The sentence is:

• הפגישה שלנו = the meeting our = our meeting
• מתחילה = begins / starts
• בשבע וחצי = at seven thirty

So the order is basically:

subject + verb + time expression

This is a very normal Hebrew sentence pattern.

Yes, but this sentence is completely natural as it is.

For example:

• הפגישה שלנו מתחילה... = our meeting starts...
• הישיבה שלנו מתחילה... = our session/meeting starts...
• הפגישה שלנו מתחילה בשעה שבע וחצי = our meeting starts at seven thirty

The given sentence is concise and everyday Hebrew.

Because in Hebrew, when telling time, שעה (hour) is often left out when it is obvious.

So both of these are possible:

• הפגישה שלנו מתחילה בשבע וחצי
• הפגישה שלנו מתחילה בשעה שבע וחצי

The version without שעה sounds very natural and common.

A common pronunciation is:

ha-p'gishá shelánu matchilá be-shéva va-chétsi

A few helpful notes:

• הפגישה = ha-p'gishá
• שלנו = shelánu
• מתחילה = matchilá
• בשבע = be-shéva
• וחצי = va-chétsi

The stress is usually near the end in several of these words, especially פגישה, שלנו, and מתחילה.

Yes. Hebrew present tense often covers what English expresses with both:

• begins / starts
• is beginning / is starting

So הפגישה שלנו מתחילה בשבע וחצי is best understood from context as Our meeting starts at 7:30, but the verb form itself does not make the same strict distinction English does.
