השחקן החדש והשחקנית החדשה לומדים יחד באוניברסיטה.

Because in Hebrew, adjectives usually come after the noun they describe.

• השחקן החדש = the new actor
• השחקנית החדשה = the new actress

So the Hebrew word order is different from English here.

Hebrew often repeats the adjective when each noun is being described separately:

• השחקן החדש
• והשחקנית החדשה

This is very natural, especially because the two nouns have different genders, so the adjective must match each one.

Hebrew can sometimes use one plural adjective after a combined phrase, but in this sentence repeating the adjective is clearer and very standard.

Because ה־ means the, and in Hebrew, when a noun is definite, its adjective usually becomes definite too.

So:

• שחקן חדש = a new actor
• השחקן החדש = the new actor

And similarly:

• שחקנית חדשה = a new actress
• השחקנית החדשה = the new actress

This is an important rule: adjectives agree not only in gender and number, but also in definiteness.

They are the masculine and feminine forms of the same kind of noun:

• שחקן = male actor
• שחקנית = female actor / actress

A lot of Hebrew nouns that refer to people have different masculine and feminine forms.

Because adjectives must agree with the noun in gender.

• השחקן is masculine singular, so the adjective is החדש
• השחקנית is feminine singular, so the adjective is החדשה

This kind of agreement is very common in Hebrew.

Because the subject is actually two people together:

• השחקן החדש
• והשחקנית החדשה

When two singular nouns are joined by and, the whole subject is plural. So the verb must also be plural.

That is why Hebrew uses לומדים = study / are studying.

In Hebrew, a mixed-gender group normally takes masculine plural agreement.

Since the sentence has:

• one man: השחקן
• one woman: השחקנית

the verb becomes לומדים rather than לומדות.

If both people were women, you would use לומדות.
If both were men, you would also use לומדים.

It can mean either one, depending on context.

Hebrew present tense does not use a separate word like am / is / are in normal sentences. So לומדים can mean:

• study
• are studying

In this sentence, the context tells you which English translation sounds best.

יחד means together.

Here:

• לומדים יחד = study together / are studying together

It often comes after the verb, as it does here. Hebrew word order is somewhat flexible, but this placement is very common and natural.

Because ב־ means in / at, and in Hebrew it attaches directly to the next word.

So:

• ב־ = in / at
• אוניברסיטה = university

When ב־ combines with a definite noun that would normally have ה־, Hebrew usually merges them rather than writing them separately.

So instead of a separate ב + ה, you get באוניברסיטה in normal spelling.

A useful thing to know: in unpointed Hebrew, באוניברסיטה can represent either in a university or in/at the university. Context usually makes the meaning clear.

Because Hebrew ו־ means and, and it is written as a prefix attached to the following word.

So:

• ו־ = and
• והשחקנית = and the actress

This is completely normal in Hebrew. Several very common short words, especially prepositions and conjunctions, attach directly to the next word instead of standing alone.
