אם המרק מלוח מדי, נוסיף לו עוד מים.

אם means if.

This sentence follows a very common Hebrew pattern:

• אם
  • condition
• then the result clause

So:

• אם המרק מלוח מדי = if the soup is too salty
• נוסיף לו עוד מים = we’ll add more water to it

Using the future in the main clause after אם is very normal in Hebrew.

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

So:

• מרק = soup
• המרק = the soup

Hebrew uses ה־ when the noun is specific or already known from context. In this sentence, we are talking about a particular soup, not soup in general.

Yes. מלוח means salty, and it is related to מלח, which means salt.

So the connection is:

• מלח = salt
• מלוח = salty

Also, מלוח is an adjective, and it agrees with the noun it describes.

Because מרק is masculine singular, the adjective is also masculine singular:

• מרק מלוח = salty soup

If the noun were feminine singular, you would usually get:

• מלוחה

In Hebrew, מדי means too / excessively, and it normally comes after the adjective.

So:

• מלוח מדי = too salty
• חם מדי = too hot
• יקר מדי = too expensive

This is different from English, where too comes before the adjective.

A learner should get used to this pattern:

• adjective + מדי

נוסיף is the first person plural future form of להוסיף, which means to add.

So:

• להוסיף = to add
• נוסיף = we will add

In this sentence, it means we’ll add.

This is very natural in a conditional sentence:

• אם... נוסיף... = if..., we’ll add...

Hebrew often leaves subject pronouns out when the verb already shows who the subject is.

Here, נוסיף already tells you the subject is we, because that verb form is first person plural future.

So:

• נוסיף = we will add

You could say אנחנו נוסיף, but it is usually unnecessary unless you want emphasis.

This is very common in Hebrew, and it often feels more natural than always saying the pronoun.

Yes, לו can mean to him, but it can also mean to it when the noun is masculine singular.

Since מרק is a masculine singular noun, לו here means:

• to it = to the soup

Hebrew does not have a separate neutral pronoun like English it in this kind of structure. Instead, it uses masculine or feminine forms depending on the noun’s grammatical gender.

So:

• לו = to him / to it (masculine singular)
• לה = to her / to it (feminine singular)

In this sentence, לו refers back to המרק.

Hebrew uses את only before a definite direct object.

Here, עוד מים means more water or some more water, which is indefinite, so there is no את.

Compare:

• נוסיף עוד מים = we’ll add more water
• נוסיף את המים = we’ll add the water

Because עוד מים is not definite, את is not used.

מים is one of those Hebrew nouns that looks plural in form but is usually translated as a mass noun: water.

So even though it ends like a plural word, in English you normally translate it as singular:

• מים = water

And:

• עוד מים = more water / some more water

This is just something learners have to get used to. Hebrew has a few common nouns like this.

Yes, often it could.

For example:

• אם המרק מלוח מדי, נוסיף עוד מים.

This still means If the soup is too salty, we’ll add more water.

Adding לו makes the relationship extra clear: the water is being added to the soup.

So both are possible, but נוסיף לו עוד מים is very natural Hebrew.

The given word order is natural, but Hebrew allows some flexibility.

For example, these are all possible:

• אם המרק מלוח מדי, נוסיף לו עוד מים.
• אם המרק מלוח מדי, נוסיף עוד מים למרק.
• אם המרק מלוח מדי נוסיף לו עוד מים.

The original sentence sounds smooth and standard. A learner should treat it as a very good model sentence.
