החוזה עדיין לא נחתם, כי בעלת הבית רצתה לשנות פרט אחד.

The prefix ה־ is the Hebrew definite article, equivalent to the in English.

So:

• חוזה = contract
• החוזה = the contract

Hebrew attaches the directly to the noun instead of writing it as a separate word.

עדיין לא means not yet.

Literally:

• עדיין = still / yet
• לא = not

In this kind of sentence, the combination is best understood as not yet:

• החוזה עדיין לא נחתם = The contract has not been signed yet

This is a very common Hebrew pattern.

נחתם is the past tense, masculine singular form of the verb להיחתם, which means to be signed.

So this is a passive-type meaning:

• חתם = he signed
• נחתם = it was signed / it got signed

Because החוזה is masculine singular, the verb is also masculine singular: נחתם.

In this sentence, נחתם does not mean signed in the active sense, but rather was signed or got signed.

Hebrew verbs in the past tense agree with the subject in gender and number.

Here the subject is החוזה (the contract), and חוזה is a masculine singular noun. So the verb must also be masculine singular:

• masculine singular: נחתם
• feminine singular: נחתמה
• masculine plural: נחתמו

That is why you get החוזה ... נחתם.

In Hebrew, the past tense is usually built into the verb itself, so you do not need a separate verb like was.

English says:

• was signed

Hebrew expresses that idea in one word:

• נחתם

So לא נחתם means was not signed / did not get signed, depending on context.

Here כי means because.

So:

• כי בעלת הבית רצתה לשנות פרט אחד = because the landlady wanted to change one detail

In modern Hebrew, כי often works like because in this kind of sentence. It can also have other meanings in other contexts, but here because is the natural translation.

בעל הבית literally means owner of the house/home, and in modern usage it can mean landlord / owner / boss of the house, depending on context.

Because the owner here is female, Hebrew uses the feminine form:

• masculine: בעל הבית
• feminine: בעלת הבית

So בעלת הבית means the landlady / the female homeowner.

This is a construct phrase, literally something like owner-ess of the house.

This is a construct chain (called סמיכות in Hebrew), where two nouns are linked together.

The basic idea is:

• בעלת = owner of
• הבית = the house / the home

Together:

• בעלת הבית = the owner of the house, often the landlady

A useful thing to notice: in construct phrases, the definiteness often appears on the second word, but the whole phrase becomes definite:

• בעלת בית = a female homeowner / a landlady
• בעלת הבית = the landlady / the female owner of the house

רצתה is the feminine singular past tense of לרצות (to want).

Because בעלת הבית is feminine singular, the verb must match it:

• masculine singular: רצה = he wanted
• feminine singular: רצתה = she wanted

So:

• בעלת הבית רצתה = the landlady wanted

לשנות is the infinitive to change.

After verbs like wanted, Hebrew often uses ל־ + infinitive, just like English uses to + verb:

• רצתה לשנות = wanted to change

This is a very common pattern:

• רוצה לאכול = wants to eat
• רצה ללכת = wanted to go
• רצתה לשנות = wanted to change

פרט means detail.

So:

• פרט אחד = one detail

Hebrew normally puts the number אחד after the noun:

• יום אחד = one day
• ספר אחד = one book
• פרט אחד = one detail

That word order is normal in Hebrew.

Because פרט is a masculine noun, the number must also be masculine.

• masculine one = אחד
• feminine one = אחת

So:

• פרט אחד = one detail
  but
• בעיה אחת = one problem

Hebrew numbers agree in gender with the noun.

Yes. The sentence structure is very natural:

• החוזה עדיין לא נחתם = main clause
• כי בעלת הבית רצתה לשנות פרט אחד = reason clause

A word-for-word breakdown is roughly:

• החוזה = the contract
• עדיין לא = not yet
• נחתם = was signed
• כי = because
• בעלת הבית = the landlady
• רצתה = wanted
• לשנות = to change
• פרט אחד = one detail

This order is completely standard in modern Hebrew.

Yes. In many contexts, נחתם can feel natural as either:

• was signed
• got signed

In this sentence, because of עדיין לא, English most naturally says:

• The contract hasn’t been signed yet

But grammatically, the Hebrew verb itself is the same one you would use for was signed / got signed in the past.

The comma separates the main statement from the reason clause:

• החוזה עדיין לא נחתם
• כי בעלת הבית רצתה לשנות פרט אחד

This is similar to English punctuation in a sentence like:

• The contract hasn’t been signed yet, because the landlady wanted to change one detail.

In Hebrew, punctuation can vary somewhat by style, but this comma is very natural here.
