בוא נמהר, כי השיעור מתחיל בעוד חמש דקות.

Yes. בוא literally means come when speaking to one male.

But in colloquial Hebrew, בוא + first-person plural future often works like come on, let’s ...

So:

• בוא נמהר = come on, let’s hurry

It is not really about physical movement here. It is a conversational way to suggest doing something together.

Yes. נמהר is the first-person plural future form of the verb למהר (to hurry).

So by itself, נמהר can mean:

• we will hurry

But after בוא, it often gets a let’s meaning:

• בוא נמהר = let’s hurry

This is a very common Hebrew pattern:

• בוא נלך = let’s go
• בוא נתחיל = let’s start
• בוא נראה = let’s see

Hebrew does not have a separate word that works exactly like English let’s in all situations.

Instead, it often expresses that idea with:

• בוא / בואי / בואו + first-person plural future

So English let’s hurry becomes Hebrew בוא נמהר.

Another very common option in speech is simply to use the first-person plural future by itself, depending on context:

• נמהר = let’s hurry / we’ll hurry

But בוא נמהר sounds more inviting or urging, like come on, let’s hurry.

Here כי means because.

So:

• כי השיעור מתחיל... = because the class starts...

It introduces the reason for hurrying.

In many cases, כי is a straightforward way to say because. Depending on style and context, Hebrew can also use other expressions, but כי is very common and natural here.

Good question. Hebrew often uses the present tense for a scheduled or near-future event, just like English often does.

So:

• השיעור מתחיל בעוד חמש דקות = literally the lesson is starting in five minutes
• natural English meaning: the class starts in five minutes

This is normal Hebrew. You may also hear future forms in some contexts, but the present tense is very common for timetabled or expected events.

Here בעוד means in, in the sense of after this amount of time.

So:

• בעוד חמש דקות = in five minutes

This is a very useful time expression in Hebrew.

Be careful: עוד by itself often means more, another, or still.
But בעוד + amount of time means in ... time:

• בעוד שעה = in an hour
• בעוד יומיים = in two days

Because דקה (minute) is a feminine noun, and the number must match the noun in the Hebrew number system used here.

So:

• חמש דקות = five minutes

This is one of the trickier parts of Hebrew for learners, because number forms do not work exactly the way English speakers expect.

For this sentence, the important thing to remember is simply:

• דקה is feminine
• therefore five minutes is חמש דקות

השיעור means the class / the lesson.

The ה־ at the beginning is the definite article, like the in English.

So:

• שיעור = a lesson / a class
• השיעור = the lesson / the class

In this sentence, it refers to a specific class that both speaker and listener know about, so the class is the natural choice.

It can mean either, depending on context.

In this sentence, השיעור מתחיל בעוד חמש דקות could be understood as:

• the lesson starts in five minutes
• the class starts in five minutes

If you are talking about a school or university setting, English often translates it as class.
If you are focusing on the instructional session itself, lesson also works.

Literally, בוא is the masculine singular form of come.

More fully, you could match it to the person you are addressing:

• בוא = to one male
• בואי = to one female
• בואו = to more than one person

So you might also hear:

• בואי נמהר = come on, let’s hurry (to one woman)
• בואו נמהר = come on, let’s hurry (to several people)

In casual modern speech, people sometimes use בוא pretty broadly, but the forms above are the grammatically matched ones.

A common pronunciation guide is:

bo ne-ma-HER, ki ha-shi-UR mat-CHIL be-OD cha-MESH da-KOT

A smoother transliteration:

• Bo nemaher, ki hashi’ur matchil be’od chamesh dakot.

A few notes:

• שיעור is usually pronounced roughly shi-UR
• מתחיל is matchil
• בעוד is be’od
• stress in דקות is on the last syllable: da-KOT
