הוא יצא מהבית בלי שלקח מפית, ועכשיו הוא מבקש ממני אחת.

מהבית is the preposition מ־ (from) attached to הבית (the house / home).

So:

• הבית = the house
• מ־ + הבית = מהבית = from the house / from home

In Hebrew, short prepositions often attach directly to the following word. When מ־ comes before a word with ה־, the result is commonly מה־.

So הוא יצא מהבית is literally he went out from the house, but in natural English it is often just he left home or he left the house.

This is the structure בלי ש־, which means without (someone) doing something.

Here:

• בלי = without
• ש־ introduces the clause
• לקח = he took

So בלי שלקח מפית means something like without his taking a napkin or more naturally without taking a napkin.

The ש־ is not translated word-for-word in natural English here; it is just part of the Hebrew clause structure.

A very common alternative would be:

בלי לקחת מפית

which also means without taking a napkin.
That version uses the infinitive (לקחת) instead of a full clause.

Because the whole sentence describes past events.

The timeline is:

1. He left the house.
2. Before or during that, he did not take a napkin.
3. Now he is asking for one.

So Hebrew can use בלי ש־ + past verb to describe something that did not happen in connection with a past event:

• הוא יצא... בלי שלקח...

This is similar in meaning to he left without taking... or he left and hadn’t taken...

Again, Hebrew could also use the infinitive here:

• הוא יצא מהבית בלי לקחת מפית

That is often the simpler version when the subject stays the same.

Because את marks a definite direct object, and מפית here is indefinite: a napkin, not the napkin.

Compare:

• לקח מפית = he took a napkin
• לקח את המפית = he took the napkin

Since the sentence means a napkin, not a specific known napkin, there is no את.

אחת means one in the feminine singular, and here it stands in place of מפית.

Since מפית is a feminine noun, Hebrew uses:

• אחת = one (feminine)
• not אחד (masculine)

So:

• הוא מבקש ממני אחת = he is asking me for one

This is very natural Hebrew. English does the same thing:

• He wants a napkin → later Now he’s asking me for one

Hebrew does not need to repeat מפית because אחת already points back to it.

Because the verb לבקש often works with the pattern:

• לבקש משהו ממישהו = to ask someone for something
• literally, to request something from someone

So in this sentence:

• מבקש = is asking
• ממני = from me
• אחת = one

So the structure is:

מבקש ממני אחת = asking me for one

This is important because English speakers often want to map it directly to ask me, but in Hebrew the person you ask is commonly marked with מ־ (from).

Yes, that is possible, but מבקש ממני אחת sounds very natural here.

Both word orders can work, but the version in your sentence first gives the source/person involved (ממני) and then the thing requested (אחת).

That order feels smooth and conversational.

So:

• מבקש ממני אחת = very natural
• מבקש אחת ממני = also understandable and possible, but a little different in emphasis

Because the subject is הוא (he), which is masculine singular.

So the verbs agree with הוא:

• הוא יצא = he went out / left
• הוא לקח = he took
• הוא מבקש = he is asking

If the subject were feminine, the forms would change:

• היא יצאה מהבית...
• בלי שלקחה מפית...
• ועכשיו היא מבקשת ממני אחת.

This is standard Hebrew agreement: verbs reflect gender and number.

Hebrew often drops subject pronouns because the verb already shows person, gender, and number.

So in some contexts you could say something like:

יצא מהבית בלי שלקח מפית, ועכשיו מבקש ממני אחת.

That can be understood.

However, keeping הוא is completely natural and often clearer, especially in a full sentence with two clauses. It helps keep the subject explicit and easy to follow.

So:

• הוא יצא... והוא מבקש... = clear and natural
• dropping הוא = possible in the right context, but less explicit

It is understandable, but many native speakers would probably more naturally say:

הוא יצא מהבית בלי לקחת מפית, ועכשיו הוא מבקש ממני אחת.

Using בלי לקחת is very common when the same person is doing both actions.

Another very natural option is:

הוא יצא מהבית בלי מפית, ועכשיו הוא מבקש ממני אחת.

That version means He left home without a napkin, and now he’s asking me for one.

So your sentence is grammatical and understandable, but בלי לקחת may sound a bit more idiomatic in everyday Hebrew.
