אם המרק יתקרר, נחמם אותו עוד פעם.

Because Hebrew normally uses the future tense in both parts of a real future condition.

So Hebrew says:

אם המרק יתקרר, נחמם אותו = literally, if the soup will cool down, we will heat it

That is completely normal in Hebrew.

In English, we usually say:

If the soup gets cold, we’ll heat it again

So this is a place where Hebrew and English work differently.

אם means if.

It introduces a condition:

אם המרק יתקרר = if the soup cools down / gets cold

It is one of the most basic and common words for conditional sentences in Hebrew.

יתקרר means will cool down, will get cold, or will become cold.

It is the 3rd person masculine singular future form of להתקרר.

Why masculine singular?

Because המרק (the soup) is grammatically masculine singular in Hebrew, so the verb matches it.

Because יתקרר means become cold / cool down, while יקרר means cool something.

This is an important difference:

• להתקרר = to get cold, to cool down
• לקרר = to cool something

So:

• המרק יתקרר = the soup will get cold
• אני אקרר את המרק = I will cool the soup

In your sentence, the soup is not cooling something else; it is itself becoming cold, so יתקרר is the correct form.

נחמם is the 1st person plural future form of לחמם, which means to heat.

So:

• נחמם = we will heat

Hebrew does not need a separate word for will. The future meaning is built into the verb itself.

The נ־ at the beginning is part of the future form for we.

אותו means him or it as a direct object.

Here it means it, referring to המרק.

So:

נחמם אותו = we will heat it

Why אותו and not another form?

Because מרק is masculine singular, and אותו is the masculine singular object pronoun.

If the noun were feminine, you would use אותה.

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

So:

• מרק = soup / a soup
• המרק = the soup

In this sentence, we are talking about a specific soup, so המרק is natural.

Yes. עוד פעם means again or one more time.

Literally, it is something like another time.

So:

נחמם אותו עוד פעם = we’ll heat it again

This is very common in everyday speech.

A more compact alternative is שוב:

אם המרק יתקרר, נחמם אותו שוב

Both are natural, but עוד פעם sounds especially conversational.

Because Hebrew does not need one here.

English often uses phrasal verbs like:

• heat up
• cool down

Hebrew usually expresses the same idea with a single verb:

• לחמם = to heat / heat up
• להתקרר = to cool down / get cold

So נחמם אותו already includes the idea of heat it up.

Yes.

You can also say:

נחמם אותו עוד פעם אם המרק יתקרר

That still means We’ll heat it again if the soup gets cold.

When the אם clause comes first, a comma is commonly used:

אם המרק יתקרר, נחמם אותו עוד פעם

When the main clause comes first, punctuation is often lighter.

A simple pronunciation guide is:

im ha-maRAK yitkaRER, nechaMEM oTO od PA'am

Approximate stress:

• אם
• המרק → maRAK
• יתקרר → yitkaRER
• נחמם → nechaMEM
• אותו → oTO
• עוד פעם → od PA'am

The stress is mostly toward the end of each word, which is very common in Hebrew.
