יש תקלה במעלית, ולכן אני לוקח את המדרגות.

יש is the Hebrew way to say there is / there are.

So יש תקלה במעלית literally means something like There is a malfunction in the elevator.

A native English speaker may expect a form of to be here, but Hebrew often uses יש for existence:

• יש זמן = there is time
• יש בעיה = there is a problem

This is one of the most common sentence patterns in Hebrew.

In present-tense Hebrew, the verb to be is usually omitted.

So Hebrew often says:

• אני עייף = I am tired
• היא בבית = she is at home

But when Hebrew means there is / there are, it usually uses יש.

That is why the sentence has יש תקלה rather than a separate word meaning is.

Because the sentence is introducing the problem as a malfunction, not the malfunction.

After יש, Hebrew very often uses an indefinite noun:

• יש בעיה = there is a problem
• יש שאלה = there is a question

So יש תקלה sounds natural: there is a malfunction / problem.

If you said יש התקלה, that would generally sound wrong in normal Hebrew.

במעלית is made of:

• ב־ = in / at / with
• ה־ = the
• מעלית = elevator

Together, ב + ה + מעלית becomes במעלית.

This is a very common Hebrew contraction with prepositions:

• בבית = in the house
• במכונית = in the car
• למשרד = to the office
• מהחדר = from the room

In this sentence, במעלית means in the elevator, but in English we often translate the whole phrase more naturally as there is a problem with the elevator.

Because languages package ideas differently.

Hebrew says literally there is a malfunction in the elevator, while English usually prefers there is a problem with the elevator.

So this is not a word-for-word match. It is just the natural Hebrew way to express the idea.

This is very common when learning Hebrew: the most natural preposition in Hebrew is not always the one English would use.

ולכן means and therefore / so / therefore.

It is made of:

• ו־ = and
• לכן = therefore

So ולכן links the two parts:

• there is a malfunction in the elevator,
• therefore I’m taking the stairs.

Yes, ולכן can sound a bit more formal or written than everyday אז (so). But it is still very common and completely natural.

Compare:

• יש תקלה במעלית, ולכן אני לוקח את המדרגות.
• יש תקלה במעלית, אז אני לוקח את המדרגות.

Both are fine; ולכן is slightly more formal or polished.

Yes, לוקח literally means take, but Hebrew uses this verb in the expression לקחת את המדרגות = to take the stairs.

That matches English fairly well, since English also says take the stairs.

Also, Hebrew present tense often covers what English says as:

• I take
• I am taking
• sometimes even I’m going to take, depending on context

So here אני לוקח את המדרגות naturally means I’m taking the stairs.

Because לוקח is the masculine singular present-tense form.

The verb is לקחת = to take.

Present tense changes for gender and number:

• אני לוקח = I take / I’m taking (male speaker)
• אני לוקחת = I take / I’m taking (female speaker)
• הוא לוקח = he takes
• היא לוקחת = she takes

So the sentence as written assumes the speaker is male. If the speaker were female, it would be:

יש תקלה במעלית, ולכן אני לוקחת את המדרגות.

את marks a definite direct object.

Since המדרגות means the stairs, it is definite, so Hebrew uses את:

• אני לוקח את המדרגות
• literally: I take the stairs

Compare:

• אני קורא ספר = I am reading a book
• אני קורא את הספר = I am reading the book

So את does not mean the. It is a special marker used before definite direct objects.

Because stairs in Hebrew is usually plural, just as it is in English.

• מדרגה = one step
• מדרגות = stairs / steps
• המדרגות = the stairs

So אני לוקח את המדרגות is literally I take the stairs.

Hebrew usually talks about a staircase this way, using the plural noun.

Yes, absolutely.

Both are natural, but there is a nuance:

• בעיה = problem (more general)
• תקלה = malfunction / fault / breakdown (more specific, often technical)

So:

• יש בעיה במעלית = there is a problem with the elevator
• יש תקלה במעלית = there is a malfunction in the elevator

If you want to sound a bit more precise or technical, תקלה is a good choice.

Yes, it is natural and helpful here because the sentence has two connected clauses:

• יש תקלה במעלית
• ולכן אני לוקח את המדרגות

The comma marks the pause before therefore / so.

In informal writing, people are not always strict with punctuation, but in standard writing the comma is appropriate here.

Yes. A very common spoken version would be:

יש בעיה במעלית, אז אני לוקח את המדרגות.

That sounds a little more casual because:

• בעיה is more everyday than תקלה
• אז is more conversational than ולכן

The original sentence is still perfectly natural; it just sounds a bit more polished or formal.
