הבחורה מחכה בחוץ.

בחורה usually means young woman or girl, depending on context.

• ילדה is more clearly girl/child
• אישה is woman
• בחורה often suggests a female who is no longer a small child, often a teenager or young adult

So הבחורה can be translated as the girl or the young woman, depending on the situation.

The prefix ה־ is the Hebrew definite article, meaning the.

So:

• בחורה = a girl / a young woman
• הבחורה = the girl / the young woman

In Hebrew, the is attached directly to the noun instead of being written as a separate word.

We know it from the subject: הבחורה is feminine singular, so the verb is understood as feminine singular too.

A useful thing to know is that in unpointed Hebrew, מחכה can look the same for:

• he is waiting
• she is waiting

The difference is usually clear from context or from the subject.

Here, because הבחורה is feminine, מחכה is understood as she is waiting.

It can mean both.

In Modern Hebrew, the present tense often covers both:

• she waits
• she is waiting

So הבחורה מחכה בחוץ can mean either:

• The girl waits outside
• The girl is waiting outside

English makes a stronger distinction here than Hebrew does.

Because in present-tense Hebrew, you normally do not use a separate word for am / is / are.

So Hebrew says:

• הבחורה מחכה בחוץ

literally something like:

• the girl waiting outside

but the natural English translation is:

• The girl is waiting outside

This is completely normal in Hebrew.

בחוץ means outside or outdoors.

It contains the prefix ב־, which often means in / at / on, attached to חוץ.

So historically/literally it is something like:

• ב + חוץ

But as a full expression, בחוץ simply means outside.

You do not need to translate the ב־ separately in normal English.

Yes. Hebrew can use מחכה by itself, just like English waiting.

So:

• הבחורה מחכה בחוץ = The girl is waiting outside

If you want to say what she is waiting for, Hebrew usually uses ל־:

• הבחורה מחכה לאוטובוס = The girl is waiting for the bus
• הבחורה מחכה לך = The girl is waiting for you

So the sentence is complete even without an object.

Yes. הבחורה מחכה בחוץ uses a very normal Hebrew word order:

• subject: הבחורה
• verb: מחכה
• adverb/place expression: בחוץ

This is the most neutral way to say it.

Hebrew word order can be flexible, but this version sounds straightforward and natural.

Here are some common changes:

• הבחור מחכה בחוץ = The young man is waiting outside
• הילדה מחכה בחוץ = The girl is waiting outside
• הבחורות מחכות בחוץ = The young women are waiting outside
• הבחורים מחכים בחוץ = The young men are waiting outside

Notice that in the plural, the verb spelling changes clearly:

• מחכות = feminine plural
• מחכים = masculine plural

That makes gender and number easier to see than in singular מחכה.

It is pronounced roughly ba-khutz.

A few pronunciation notes:

• ב here sounds like b
• ח is a throaty sound, often written kh in transliteration
• וּ gives the u sound
• ץ at the end sounds like ts

So a rough English-style approximation is ba-khoots, though the kh sound is not exactly an English sound.
