כדאי שתוסיפי קצת שום ופלפל למרק, כי היום הוא לא מספיק טעים.

כדאי is a very common word meaning something like it’s advisable, it’s a good idea, or it’s worth.

In this sentence, כדאי introduces a recommendation:

כדאי שתוסיפי... = You should add... / It would be a good idea to add...

A very common pattern is:

כדאי ש + future verb

So Hebrew often expresses advice with כדאי plus a clause, rather than using a direct equivalent of English should.

After כדאי ש..., Hebrew normally uses the future tense to talk about a suggested action.

So:

• כדאי שתוסיפי literally looks like It’s advisable that you will add
• but in natural English it means You should add

This is very normal Hebrew grammar. The future form after ש does not necessarily mean far-future time; it often marks a recommended or expected action.

Because of the verb תוסיפי.

This is the second person feminine singular future form of להוסיף (to add).

So:

• תוסיפי = you (feminine singular) will add / should add
• תוסיף = you (masculine singular) will add / should add

Hebrew verbs often show the gender of the person being addressed, unlike English.

The ש is the short form of אשר / ש־, and here it means that.

So:

• כדאי שתוסיפי = It’s advisable that you add...

In modern Hebrew, this attached ש־ is extremely common. It often introduces a subordinate clause, just like that in English.

Yes. קצת means a little, some, or a bit of.

In קצת שום ופלפל, it naturally applies to the whole phrase:

• a little garlic and pepper
• or some garlic and pepper

Hebrew does not need to repeat קצת before both nouns, although it could in some contexts:

• קצת שום וקצת פלפל = a little garlic and a little pepper

The version in your sentence is more compact and natural.

Because they are being used as general ingredient nouns, not as specific identifiable items.

• שום = garlic
• פלפל = pepper

In recipes or food suggestions, Hebrew often uses ingredient words without the definite article, just like English often says add garlic or add pepper, not necessarily add the garlic.

If you were referring to specific garlic or specific pepper already known in the conversation, you might use the definite article, but here the general form is the natural one.

למרק means to the soup.

It is made from:

• ל־ = to
• המרק = the soup

When ל־ combines with ה־, they contract:

• ל + המרק → למרק

This kind of contraction is very common in Hebrew:

• לבית = to the house
• לילד = to the boy
• למרק = to the soup

Here הוא refers to המרק (the soup), which is a masculine singular noun.

In Hebrew, nouns have grammatical gender, and the matching pronoun is used:

• מרק is masculine
• so the pronoun is הוא

In English we would usually say it, but Hebrew uses the masculine or feminine pronoun based on the noun’s gender.

So here הוא really means it, referring to the soup.

In this sentence, הוא helps make the second clause clear:

כי היום הוא לא מספיק טעים = because today it is not tasty enough

Hebrew present-tense sentences often do not use a verb like is, so the pronoun can help identify the subject.

Without הוא, the clause would feel less complete or less clear here, because לא מספיק טעים is just the predicate not tasty enough, and הוא gives you the subject: the soup / it.

So while Hebrew sometimes leaves things out when the context is obvious, here הוא is natural and useful.

Because it agrees with מרק, which is a masculine singular noun.

In Hebrew, adjectives usually agree with the noun they describe in gender and number.

So:

• מרק טעים = a tasty soup
• המרק טעים = the soup is tasty

If the noun were feminine, the adjective would also be feminine:

• המרקחת טעימה = the jam is tasty

Here, since מרק is masculine singular, טעים is the correct form.

מספיק here means enough, and it modifies the adjective טעים.

So:

• טעים = tasty
• מספיק טעים = tasty enough
• לא מספיק טעים = not tasty enough

This is a very common Hebrew structure:

• לא מספיק גדול = not big enough
• לא מספיק מהר = not fast enough
• לא מספיק מעניין = not interesting enough

So מספיק works a lot like English enough in this kind of sentence.

Its basic meaning is today, but in context it can also feel like today / this time / as it is now.

In this sentence, כי היום הוא לא מספיק טעים can suggest something like:

• because today it’s not tasty enough
• because right now it’s not tasty enough
• because this time it’s not tasty enough

So היום keeps its literal meaning, but in natural speech it can also point to the soup’s current condition.

Because in the present tense, Hebrew usually does not use a copula like English am / is / are.

So:

• הוא טעים literally = he/it tasty
• natural English = it is tasty

Likewise:

• הוא לא מספיק טעים literally = it not enough tasty
• natural English = it is not tasty enough

This is one of the biggest differences from English. In the present tense, Hebrew often simply puts the subject and adjective together without a separate verb meaning is.

The word order is natural and straightforward:

• כדאי שתוסיפי... = recommendation first
• למרק = where to add it
• כי... = reason afterwards

Hebrew word order is somewhat flexible, but this version sounds very normal. The sentence gives:

1. the advice
2. what to add
3. where to add it
4. the reason

That makes it easy to follow and very idiomatic.
