אם לא יהיה קפה בבית, אני אקנה קפה במשרד.

יש means there is / there are and is normally used for the present:

• יש קפה בבית = There is coffee at home

But this sentence is talking about the future, so Hebrew uses the future form of היה:

• יהיה קפה בבית = There will be coffee at home

So:

• אם לא יהיה קפה בבית = If there won’t be coffee at home

A useful contrast:

• אם אין קפה בבית = If there is no coffee at home
• אם לא יהיה קפה בבית = If there will be no coffee at home

Hebrew commonly uses the future tense in both the if-clause and the main clause when talking about a future possibility.

So:

• אם לא יהיה... = If there won’t be...
• אני אקנה... = I will buy...

This is different from English, where we usually say:

• If there is no coffee at home, I’ll buy coffee at the office

English often uses present tense after if, even for future meaning. Hebrew does not have to do that here; future + future is normal.

אם means if.

In this sentence:

• אם לא יהיה קפה בבית = If there won’t be coffee at home

It introduces a condition.

Be careful not to confuse it with another common Hebrew word that sounds similar in some contexts:

• אִם = if
• אֵם = mother

They are spelled differently, even if learners sometimes mix them up at first.

לא is the standard Hebrew word for not.

So:

• יהיה = will be
• לא יהיה = will not be / won’t be

Hebrew usually places לא directly before the verb it negates.

Examples:

• אני אקנה = I will buy

• אני לא אקנה = I will not buy

• יהיה קפה = There will be coffee
• לא יהיה קפה = There will not be coffee

Hebrew often expresses there is / there are / there will be without a separate word that exactly matches English there.

For example:

• יש קפה = There is coffee
• יהיה קפה = There will be coffee

So in Hebrew, the idea of existence is built into יש or יהיה, and you do not need an extra dummy subject like English there.

Yes. יהיה is masculine singular future, and it matches קפה, which is treated as a masculine singular noun.

So:

• קפה = masculine singular
• יהיה קפה = there will be coffee

Compare:

• יהיה ספר = there will be a book
• תהיה מכונית = there will be a car
• יהיו ספרים = there will be books

So if the noun changes in gender or number, the verb may change too.

בבית is made of:

• ב־ = in / at
• בית = house / home

So בבית literally means in the house or at home, depending on context.

In this sentence, the natural English meaning is:

• בבית = at home

Hebrew often uses בית where English prefers home.

Because בבית describes location, while הביתה describes direction.

• בבית = at home / in the house
• הביתה = homeward / to home

So:

• אני בבית = I am at home
• אני הולך הביתה = I am going home

In your sentence, the meaning is location:

• If there won’t be coffee at home...

So בבית is correct.

אקנה means I will buy.

It comes from the root ק-נ-ה and is the first person singular future form.

The א־ at the beginning is a common marker for I in the future tense.

Examples:

• אקנה = I will buy
• אכתוב = I will write
• אלמד = I will study

So:

• אני אקנה קפה = I will buy coffee

Yes, אקנה already means I will buy, so the pronoun אני is not strictly necessary.

Hebrew often allows subject pronouns to be omitted when the verb already makes the subject clear.

So both are possible:

• אקנה קפה במשרד
• אני אקנה קפה במשרד

Adding אני can make the sentence a little clearer, more explicit, or slightly more emphatic.

Hebrew often repeats the noun where English might prefer a pronoun.

So Hebrew says:

• אני אקנה קפה = I will buy coffee

rather than necessarily using something like it.

You could sometimes rephrase in other ways, but repeating קפה is completely natural and clear here.

It also avoids ambiguity: the speaker is specifically saying what they will buy.

במשרד is made of:

• ב־ = in / at
• משרד = office
• with the definite article built in: the office

So במשרד literally means in the office or at the office.

In many contexts, the most natural English translation is:

• at the office

Hebrew ב־ often covers both in and at, depending on context.

Because in Hebrew, prepositions like ב־ often combine with the definite article ה־.

So:

• משרד = office
• ה + משרד = the office
• ב + ה + משרד becomes במשרד = in the office / at the office

This happens with other prepositions too:

• לבית = to a house / home
• לבית הספר = to the school
• בשולחן = on the table
• בבית can mean in a house or at home, depending on context

Because the sentence is talking about coffee in a general, uncountable sense, not a specific coffee.

• קפה = coffee
• הקפה = the coffee

Here, the meaning is general:

• If there is no coffee at home, I’ll buy coffee at the office

That is why קפה appears without ה־.

This word order is very natural, but Hebrew word order is somewhat flexible.

The sentence as written is straightforward:

• אם לא יהיה קפה בבית, אני אקנה קפה במשרד.

You may also hear slightly different arrangements depending on emphasis, for example placing the location earlier or later. But for a learner, the given order is a very good standard pattern:

• If not + verb + noun + place, I + future verb + noun + place

So it is not the only possible order, but it is a normal and useful one.

יהיה is usually pronounced approximately yih-yeh.

It can look unusual because it comes from the verb היה (to be) and contains letters that make the form seem repetitive to learners.

A simple way to recognize it is:

• היה = was
• יהיה = will be

Even if the spelling feels strange at first, this is a very common word, so it becomes familiar quickly.
