החגורה הזאת יפה, אבל אני רוצה חגורה פשוטה יותר לשמלה הזאת.

That is normal Hebrew word order.

• חגורה פשוטה = a simple belt
• החגורה הזאת = this belt

In Hebrew, descriptive adjectives usually come after the noun, and demonstratives like הזה / הזאת usually come after the noun too. So English this belt and simple belt become Hebrew belt this and belt simple.

ה־ is the definite article, meaning the.

• החגורה הזאת = this belt → a specific belt
• השמלה הזאת = this dress → a specific dress
• חגורה פשוטה יותר = a simpler belt → not a specific belt, just any belt of that type

Hebrew has no separate word for a/an, so a bare noun like חגורה can mean a belt.

Because חגורה and שמלה are feminine nouns.

In Hebrew, adjectives and demonstratives must agree with the noun in gender and number.

So here you get feminine singular forms:

• החגורה הזאת
• חגורה פשוטה יותר
• השמלה הזאת

If the noun were masculine, the forms would change, for example:

• הספר הזה
• ספר פשוט יותר

Because in unpointed Hebrew, masculine singular yafé and feminine singular yafá are both spelled יפה.

So the spelling stays the same, but the pronunciation changes based on grammar.

In this sentence, חגורה is feminine, so יפה is understood as yafá.

In present-tense Hebrew, the verb to be is usually omitted.

So:

• החגורה הזאת יפה

literally looks like this belt pretty, but it means this belt is pretty.

Hebrew does use forms of to be in past and future, but usually not in simple present-tense sentences like this one.

Hebrew usually forms the comparative with יותר, meaning more.

So:

• פשוטה יותר = more simple = simpler

This is the normal Hebrew way to say -er meanings.

If you want to say than, you usually add מ־:

• חגורה פשוטה יותר מהחגורה הזאת = a simpler belt than this belt

You may also hear יותר פשוטה. Both word orders are possible.

Because the preposition ל־ combines with the definite article ה־.

So:

• ל + השמלה becomes לשמלה

This happens a lot in Hebrew with short prepositions like ל־, ב־, and כ־.

Here לשמלה הזאת means for this dress or to go with this dress.

Yes. It is spelled the same in normal Hebrew writing, but pronounced differently.

• male speaker: ani rotzé
• female speaker: ani rotzá

So אני רוצה can be used by either a man or a woman, but the pronunciation changes.

Yes. Both are common.

• החגורה הזאת
• החגורה הזו

Both mean this belt.

Likewise:

• השמלה הזאת
• השמלה הזו

Both mean this dress.

הזאת can sound a little fuller or slightly more emphatic, while הזו is very common in everyday speech.

Because Hebrew often repeats the noun where English uses one.

So English might say:

• This belt is pretty, but I want a simpler one

But Hebrew very naturally says:

• החגורה הזאת יפה, אבל אני רוצה חגורה פשוטה יותר

Repeating the noun is completely normal and often the most natural choice.

A natural pronunciation is:

ha-chagorá hazót yafá, avál aní rotzé/rotzá chagorá pshutá yotér la-simlá hazót

A few helpful notes:

• rotzé if the speaker is male
• rotzá if the speaker is female
• יפה here is pronounced yafá
• ch represents the Hebrew ח sound, like the sound in Scottish loch or German Bach
