אנחנו צריכים הסכם הוגן.

Because the subject is אנחנו (we), and in Hebrew the adjective/participle used after the subject has to agree with it.

Here, צריכים is the masculine plural form of צריך (need / needing).

• אני צריך = I need (masculine speaker)
• אני צריכה = I need (feminine speaker)
• אנחנו צריכים = we need (masculine or mixed group)
• אנחנו צריכות = we need (all-female group)

So צריכים matches אנחנו.

In modern Hebrew, צריך / צריכה / צריכים / צריכות is very commonly used to express need.

Literally, it behaves more like necessary / in need of, but in normal English it is translated as need.

So:

• אני צריך מים = I need water
• אנחנו צריכים הסכם הוגן = We need a fair agreement

You can think of צריך as a very common Hebrew way to say need, even though its grammar does not work exactly like the English verb to need.

Hebrew requires grammatical gender in the plural.

• צריכים = masculine plural
• צריכות = feminine plural

The masculine plural is used for:

• a group of men
• a mixed group
• a group whose gender is unspecified

The feminine plural is used only for an all-female group.

So if the group is mixed or unknown, אנחנו צריכים is the normal default.

Hebrew does not have an indefinite article like English a / an.

So:

• הסכם can mean an agreement or agreement, depending on context.
• ההסכם means the agreement.

That means:

• אנחנו צריכים הסכם הוגן = We need a fair agreement
• אנחנו צריכים את ההסכם ההוגן = We need the fair agreement

English must choose between a and the, but Hebrew often leaves the indefinite form with no extra word.

In Hebrew, adjectives usually come after the noun they describe.

So:

• הסכם הוגן = a fair agreement
• בית גדול = a big house
• ילדה חכמה = a smart girl

This is the normal word order in Hebrew:

• noun + adjective

Also, the adjective must agree with the noun in gender and number.

Here:

• הסכם is masculine singular
• הוגן is masculine singular

So they match.

Because both are masculine singular.

Hebrew adjectives agree with the nouns they describe in:

• gender
• number
• definiteness

Here are some forms of fair:

• הוגן = masculine singular
• הוגנת = feminine singular
• הוגנים = masculine plural
• הוגנות = feminine plural

Examples:

• הסכם הוגן = a fair agreement
• עסקה הוגנת = a fair deal
• הסכמים הוגנים = fair agreements

Because את is used before a definite direct object, not an indefinite one.

Here, הסכם means a fair agreement, not the fair agreement, so there is no את.

Compare:

• אנחנו צריכים הסכם הוגן = We need a fair agreement
• אנחנו צריכים את ההסכם ההוגן = We need the fair agreement

A quick rule:

• no את with an indefinite noun
• usually את with a definite direct object

Yes. אנחנו צריכים is the normal present-tense way to say we need.

Hebrew present-tense forms often look like adjectives or participles, but they function as present tense in everyday speech.

So:

• אנחנו צריכים = we need / we are needing (normally just translated as *we need)*
• הוא צריך = he needs
• היא צריכה = she needs

There is no separate word here for are. Hebrew usually does not use a present-tense form of to be in sentences like this.

Then צריכים would become צריכות:

• אנחנו צריכות הסכם הוגן.

Everything else stays the same, because הסכם הוגן is still masculine singular.

Only the word agreeing with אנחנו changes.

A simple pronunciation guide is:

Anákhnu tzrikhím heském hogén.

A few notes:

• אנחנו = a-NAKH-nu
• צריכים = tzri-KHIM
• הסכם = hes-KEM
• הוגן = ho-GEN

The kh sound is the throaty Hebrew sound, like ch in German Bach or Scottish loch.

Yes. Another common option is זקוקים ל־ / זקוקות ל־, which is a bit more formal or stylistically different.

For example:

• אנחנו צריכים הסכם הוגן = We need a fair agreement
• אנחנו זקוקים להסכם הוגן = We need a fair agreement

Notice that with זקוקים, Hebrew uses ל־ (to / for) before the noun:

• זקוקים להסכם

But with צריכים, you normally say:

• צריכים הסכם

Both are correct, but צריכים is extremely common in everyday Hebrew.
