חשוב שתבדקי אם יש רוכסן טוב בכיס הפנימי של התיק.

Because the sentence is addressing one woman.

• תבדקי = you will check / you should check (addressing feminine singular)
• If you were speaking to a man, it would be שתבדוק
• If you were speaking to more than one person, the form would change again

Hebrew verbs often show the gender and number of the person being addressed, unlike English.

Yes, תבדקי is formally a future-tense form, but after expressions like חשוב ש־ it often has a meaning closer to:

• that you check
• you should check
• make sure you check

So:

• חשוב = it is important
• שתבדקי = that you check

Together, חשוב שתבדקי means it’s important that you check.

This is very common in Hebrew: future forms are often used after ש־ to express something like a recommendation, expectation, or necessity.

In Hebrew, it is very natural to say simply חשוב for it is important.

So:

• חשוב שתבדקי... = It’s important that you check...

You could sometimes hear זה חשוב ש..., but in many cases Hebrew prefers the shorter structure without זה.

This is similar to how Hebrew often omits words that English requires.

The ש־ is the short form of אשר / that, and here it means that.

So:

• חשוב שתבדקי = it’s important that you check

It connects the first idea to the clause that follows.

Because ש־ is attached directly to the next word, ש + תבדקי becomes שתבדקי.

Here, אם means whether.

So:

• אם יש רוכסן טוב... = whether there is a good zipper...

In English, if and whether can sometimes overlap, and Hebrew אם works the same way in many contexts.

Here it is not really a condition like If it rains...
It is introducing something to check: check whether...

יש means there is / there are or there exists.

So:

• יש רוכסן טוב = there is a good zipper

Hebrew often uses יש where English uses there is.

Examples:

• יש מים = There is water / There are waters? usually There is water
• יש בעיה = There is a problem

So in this sentence, אם יש רוכסן טוב means whether there is a good zipper.

In Hebrew, adjectives usually come after the noun.

So:

• רוכסן טוב = a good zipper
• literally: zipper good

This is normal Hebrew word order for noun + adjective.

More examples:

• תיק גדול = a big bag
• כיס פנימי = an inner pocket

The prefix ב־ means in.

So:

• בכיס = in a pocket / in the pocket, depending on context

Here it is part of:

• בכיס הפנימי של התיק = in the inner pocket of the bag

Also notice:

• כיס = pocket
• פנימי = inner / internal

So הכיס הפנימי means the inner pocket.

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

So:

• כיס פנימי = an inner pocket
• הכיס הפנימי = the inner pocket

Both words become definite:

• הכיס = the pocket
• הפנימי = the inner

This is a very important Hebrew rule: adjectives agree with the noun in definiteness, as well as gender and number.

של is the common modern Hebrew way to say of or show possession.

So:

• הכיס הפנימי של התיק = the inner pocket of the bag / the bag’s inner pocket

This is often easier and more common in everyday Hebrew than using the construct state.

A more compact form is sometimes possible in Hebrew, but של is extremely normal and natural.

Yes, that is a very natural English translation.

Literally, the Hebrew is closer to:

• It’s important that you check whether there is a good zipper in the bag’s inner pocket

But in natural English, depending on context, you might also say:

• Make sure there’s a good zipper in the inner pocket of the bag
• Be sure to check whether the bag’s inner pocket has a good zipper

So the Hebrew structure is a bit more explicit than the most natural English version.

רוכסן means zipper.

So:

• רוכסן טוב = a good zipper

Depending on context, good could mean:

• strong
• high quality
• functioning properly
• reliable

So the sentence is not just asking whether there is a zipper, but whether it is a good one.

Yes. פנימי is a common adjective meaning:

• inner
• internal
• inside

So:

• כיס פנימי = inner pocket
• דלת פנימית = internal door
• בעיה פנימית = internal problem

Here, הכיס הפנימי clearly means the pocket on the inside of the bag.

You would change שתבדקי to שתבדוק.

So:

• חשוב שתבדקי אם יש רוכסן טוב בכיס הפנימי של התיק.
  = said to a woman

• חשוב שתבדוק אם יש רוכסן טוב בכיס הפנימי של התיק.
  = said to a man

Everything else stays the same.

It comes from the root ב־ד־ק, which has to do with checking / examining.

The base verb is:

• לבדוק = to check

From that verb:

• תבדקי = you (feminine singular) will check
• with ש־ attached: שתבדקי = that you check

This is useful because once you know the infinitive לבדוק, you can recognize related forms more easily.

Hebrew expresses that relationship differently.

Instead of putting the owner first, Hebrew says:

• the inner pocket of the bag
• הכיס הפנימי של התיק

English can say both:

• the inner pocket of the bag
• the bag’s inner pocket

Hebrew normally uses the first structure here.

So the Hebrew word order may feel reversed compared with English, but it is completely natural.
