אם תשתמשי בפטיש הגדול הזה, את יכולה לפגוע בקיר.

Because the sentence is addressed to one female person.

You can see that in three places:

• תשתמשי = you will use / you use (feminine singular)
• את = you (feminine singular)
• יכולה = can / able to (feminine singular)

If you were speaking to a man, you would say:

אם תשתמש בפטיש הגדול הזה, אתה יכול לפגוע בקיר.

So this sentence is specifically talking to a woman.

אם means if.

It introduces a condition:

• אם תשתמשי... = if you use...

This is very common in Hebrew. Just like in English, אם starts the if-clause.

So the sentence structure is:

• אם תשתמשי בפטיש הגדול הזה = if you use this big hammer
• את יכולה לפגוע בקיר = you can damage/hit the wall

Hebrew often uses the future tense after אם to talk about a possible future condition.

So:

• אם תשתמשי literally looks like if you will use
• but in natural English it is usually translated as if you use

This is normal Hebrew usage. It does not sound overly formal or strange.

So in conditional sentences, future Hebrew often corresponds to simple present English:

• אם תבואי, נדבר = If you come, we’ll talk

תשתמשי comes from the verb להשתמש = to use.

This verb is in the pattern called hitpa'el, and its basic present forms are:

• משתמש = using / uses (masculine singular)
• משתמשת = using / uses (feminine singular)

The form תשתמשי is future, second person feminine singular:

• you (f.s.) will use
• in context: if you use

A very important detail: להשתמש normally takes the preposition ב־ before the thing being used:

• להשתמש בפטיש = to use a hammer
• literally, something like to make use of a hammer

So תשתמשי בפטיש is the correct structure.

Yes, ב־ often means in, but it also has other common uses.

Here, it is required by the verb להשתמש:

• להשתמש ב... = to use ...

So:

• בפטיש = with / using a hammer in this context

This is just how the verb works in Hebrew. You do not say להשתמש פטיש.

Examples:

• אני משתמשת בעט. = I use a pen.
• הוא משתמש במחשב. = He uses a computer.

So the ב־ here is part of the normal grammar of להשתמש.

Because in Hebrew, adjectives usually come after the noun.

So:

• פטיש גדול = a big hammer
• הפטיש הגדול = the big hammer

The noun comes first, then the adjective.

Also, when the noun is definite, the adjective must also be definite. That means both get ה־:

• פטיש גדול = a big hammer
• הפטיש הגדול = the big hammer

So Hebrew says literally:

• the-hammer the-big

That is completely normal Hebrew word order.

In Hebrew, demonstratives like הזה / הזאת / האלה usually come after the noun.

So:

• הפטיש הזה = this hammer
• הפטיש הגדול הזה = this big hammer

That is the normal Hebrew order:

noun + adjective + this

Also note that הזה must match the noun in gender and number:

• הפטיש הזה = this hammer (masculine singular)
• המחברת הזאת = this notebook (feminine singular)
• הספרים האלה = these books

So הגדול הזה is not strange in Hebrew; it is exactly how Hebrew normally says this big hammer.

Yes. Both words must agree with פטיש.

פטיש is masculine singular, so the words that describe it must also be masculine singular:

• גדול = big (masculine singular)
• הזה = this (masculine singular)

That gives:

• הפטיש הגדול הזה

If the noun were feminine, the forms would change. For example:

• הקופסה הגדולה הזאת = this big box

So Hebrew agreement is very important:

• noun gender
• singular/plural
• definiteness in adjectives

Good question. Hebrew often uses יכול / יכולה plus an infinitive to express ability, just like English can / be able to.

So:

• את יכולה לפגוע בקיר = you can damage the wall / you are able to damage the wall

This is very natural Hebrew.

You could also say תוכלי in some contexts, but יכולה + infinitive is extremely common, especially for general ability or possibility.

Compare:

• את יכולה לפגוע בקיר = you can damage the wall
• את תוכלי לפגוע בקיר = you will be able to damage the wall

In this sentence, יכולה sounds like a warning about possibility:
If you use this big hammer, you can/might damage the wall.

לפגוע has a range of meanings depending on context. It can mean things like:

• to hit
• to hurt
• to harm
• to damage

In this sentence, because the object is a wall, the most natural meaning is:

• to damage the wall
• or possibly to hit the wall

If the intended meaning shown to the learner is something like damage, that fits the context very well.

This verb often suggests causing harm or impact, not just neutral physical contact.

Because לפגוע often takes the preposition ב־ before the thing or person affected.

So:

• לפגוע במישהו = to hurt someone
• לפגוע בקיר = to hit/damage the wall

Again, this is just how the verb works grammatically.

So there are actually two different ב־ prefixes in the sentence, for two different reasons:

• תשתמשי בפטיש — required by להשתמש
• לפגוע בקיר — required by לפגוע

Even though both use ב־, they belong to different verb patterns.

Yes, it could often be omitted, but here it helps make the sentence clearer.

Hebrew frequently drops subject pronouns when the verb already shows the person. But in this sentence, the second part is:

• את יכולה לפגוע בקיר

The word יכולה tells us feminine singular, but by itself it could mean:

• you (feminine) can
• or she can

So adding את makes it clear that the sentence is still speaking to you, not talking about she.

Without the pronoun, יכולה לפגוע בקיר might sound less clear in isolation.

Here are the main versions:

To one man

אם תשתמש בפטיש הגדול הזה, אתה יכול לפגוע בקיר.

To one woman

אם תשתמשי בפטיש הגדול הזה, את יכולה לפגוע בקיר.

To a group of men / mixed group

אם תשתמשו בפטיש הגדול הזה, אתם יכולים לפגוע בקיר.

To a group of women

אם תשתמשו בפטיש הגדול הזה, אתן יכולות לפגוע בקיר.

Notice:

• תשתמש / תשתמשי / תשתמשו change with person and gender/number
• אתה / את / אתם / אתן also change
• יכול / יכולה / יכולים / יכולות also agree

The sentence is built like this:

אם + verb + object, subject + יכולה + infinitive + object

More specifically:

• אם תשתמשי בפטיש הגדול הזה = if you use this big hammer
• את יכולה לפגוע בקיר = you can damage the wall

A very literal breakdown is:

• אם = if
• תשתמשי = you use / will use
• בפטיש הגדול הזה = with this big hammer
• את = you
• יכולה = can / are able
• לפגוע = to damage / hit
• בקיר = the wall

So the overall structure is quite natural Hebrew, even though some parts do not line up exactly with English word-for-word.
