כדי לשחרר את התריס התקוע, השיפוצניק בדק הכול לאט.

כדי introduces a purpose: in order to, so as to.

So כדי לשחרר... means in order to free/release/unjam...

A very common pattern is:

כדי + infinitive

For example: כדי להבין = in order to understand
כדי לפתוח = in order to open

In your sentence, it explains why the handyman checked everything slowly.

Because after כדי, Hebrew usually uses the infinitive form, which often begins with ל־.

So:

לשחרר = to release / to free / to unjam

This is the infinitive, similar to English to release.

If Hebrew wanted a full clause instead, it could use a different structure such as כדי ש־..., but כדי + infinitive is the simplest and most common pattern here.

Yes, literally לשחרר means to release, to free, or to let go.

But in real-life usage, it often extends to things like:

• freeing something that is stuck
• loosening something
• unjamming something

So with התריס התקוע, לשחרר is very natural for freeing or unsticking the shutter/blind.

תריס usually refers to a shutter or blind, especially in Israeli everyday usage.

Depending on context, it can mean:

• a window shutter
• a rolling shutter
• a blind

So English translation may vary a little depending on the kind of window covering being discussed.

את marks a definite direct object.

Since התריס means the shutter/blind, it is definite because of ה־. When a definite noun is the direct object of a verb, Hebrew normally uses את.

So:

לשחרר את התריס = to free the shutter

Compare: לשחרר תריס = to free a shutter
לשחרר את התריס = to free the shutter

Because in Hebrew, if a noun is definite, its adjective is usually definite too.

So:

תריס תקוע = a stuck shutter
התריס התקוע = the stuck shutter

This is a very important Hebrew pattern:

הילד הקטן = the small boy
הדלת הסגורה = the closed door

The adjective agrees with the noun in:

• definiteness
• gender
• number

Because תריס is masculine singular, so the adjective must also be masculine singular.

Here the adjective is תקוע, meaning stuck or jammed.

Other forms would be:

• תקועה = feminine singular
• תקועים = masculine plural
• תקועות = feminine plural

So if the noun were feminine, you would need a different form.

שיפוצניק is a very common Israeli Hebrew word, but it is somewhat colloquial.

It means something like:

• handyman
• renovation worker
• repairman (depending on context)

It comes from שיפוץ = renovation plus the suffix ־ניק, which appears in some informal nouns.

More neutral or formal alternatives might be:

• איש שיפוצים
• בעל מקצוע

But שיפוצניק is extremely natural in everyday speech.

With הכול/הכל meaning everything, Hebrew often allows both patterns:

• בדק הכול
• בדק את הכול

Both are common and natural.

With an ordinary definite noun, את is usually required, as in את התריס. But הכול behaves a little differently, and many speakers use it without את.

So the sentence sounds normal as written, and בדק את הכול לאט would also be natural.

Yes. They are two spellings of the same word.

Both mean everything or all and are pronounced hakol.

In unpointed modern Hebrew, you may see:

• הכול
• הכל

The version with ו is a fuller spelling, but the meaning is the same.

לאט is an adverb meaning slowly, and Hebrew often places adverbs after the verb phrase or near the end of the clause.

So:

השיפוצניק בדק הכול לאט = the handyman checked everything slowly

That word order is very natural.

Hebrew does allow some flexibility, so you might also hear things like: השיפוצניק לאט בדק הכול only in marked or unusual contexts, or
השיפוצניק בדק לאט את הכול

But the sentence’s version is a normal, neutral order.

Yes. It is very natural.

The structure is:

כדי לשחרר את התריס התקוע, = purpose phrase
השיפוצניק בדק הכול לאט. = main clause

So Hebrew is doing something very similar to English: In order to..., he...

You could also move the purpose phrase to the end:

השיפוצניק בדק הכול לאט כדי לשחרר את התריס התקוע.

That is also correct. Putting the purpose phrase first gives it a little more emphasis and makes the sentence flow nicely.
