אם התריס ייתקע שוב, אל תנסי לתקן אותו לבד עם פטיש.

אם means if. In Hebrew, a real or likely condition is often expressed with אם + future.

So:

• אם התריס ייתקע שוב = If the shutter/blind gets stuck again

Even though English sometimes uses the present after if (if it gets stuck), Hebrew commonly uses the future here: ייתקע.

תריס usually means a shutter or blind. Depending on context, it can refer to:

• a window shutter
• a roller shutter
• sometimes a window blind

It is a masculine singular noun, which matters for words that refer back to it, like אותו.

ייתקע means will get stuck, will jam, or will be stuck in context.

It comes from the verb להיתקע, which means:

• to get stuck
• to become jammed
• to be unable to move properly

So:

• התריס ייתקע = the shutter/blind will get stuck

This is a 3rd person masculine singular future form, matching התריס.

This is a normal spelling for this future form in modern Hebrew orthography.

• יִתָּקַע is the vocalized form
• ייתקע is the usual unvocalized spelling

The extra י helps represent the vowel pattern in standard writing without ניקוד.

So for learners, the important thing is simply to recognize ייתקע as the future form of להיתקע.

אל is used for a negative command: don’t ...

So:

• אל תנסי = don’t try

By contrast, לא usually means plain not and is used for statements, not standard direct prohibitions.

Compare:

• את לא מנסה = you are not trying
• אל תנסי = don’t try

So in commands, אל + future form is the normal pattern.

Because the speaker is talking to one female person.

• תנסי = you (feminine singular) will try / should try / try
• תנסה = you (masculine singular)

In negative commands with אל, Hebrew uses these future forms:

• אל תנסה — to one man
• אל תנסי — to one woman
• אל תנסו — to more than one person

So this sentence is specifically addressed to a woman.

After the verb לנסות (to try), Hebrew usually uses another verb in the infinitive with ל־.

So:

• לנסות לתקן = to try to fix

In the sentence:

• אל תנסי לתקן = don’t try to fix

This is very similar to English try to fix.

אותו means it or him, depending on context. Here it means it, and it refers back to התריס.

Since תריס is a masculine noun, Hebrew uses the masculine object form:

• אותו = it/him (masculine singular)

If the noun were feminine, you would expect אותה.

So:

• לתקן אותו = to fix it

לבד means alone or by yourself.

In this sentence:

• לתקן אותו לבד = to fix it by yourself / on your own

Even though the sentence is addressed to a woman, לבד is very commonly used as-is in everyday Hebrew. You may also encounter the more explicitly feminine form לבדה, but לבד is extremely normal in speech.

Literally, עם פטיש means with a hammer.

Here it describes the tool being used:

• אל תנסי לתקן אותו לבד עם פטיש = don’t try to fix it by yourself with a hammer

The tone suggests that using a hammer would be a bad or reckless idea. So the phrase may carry a practical nuance like:

• don’t try to fix it yourself using a hammer
• don’t go at it with a hammer

But grammatically, it simply means with a hammer.

Yes, שוב means again.

Here it appears after the verb:

• אם התריס ייתקע שוב = if the shutter gets stuck again

That placement is very natural. Hebrew is somewhat flexible with adverb placement, but this position is common and sounds normal.

It has two main parts:

1. אם התריס ייתקע שוב

   • conditional clause
   • if the shutter gets stuck again

2. אל תנסי לתקן אותו לבד עם פטיש

   • main clause, negative command
   • don’t try to fix it by yourself with a hammer

So the pattern is:

• If X happens, don’t do Y.

This structure is very common in Hebrew.

You would change תנסי to תנסה:

• אם התריס ייתקע שוב, אל תנסה לתקן אותו לבד עם פטיש.

Everything else stays the same.

So:

• אל תנסי — to a woman
• אל תנסה — to a man

It sounds like normal, everyday modern Hebrew.

Nothing in it is especially literary or unusually formal. A native speaker could easily say this in ordinary conversation, especially in a practical household situation.
