הפעולה הזאת חשובה.

A common pronunciation is:

ha-pe'u-LA ha-ZOT kha-shu-VA

A few notes:

• ה at the beginning usually sounds like ha-.
• פעולה is stressed on the last syllable: pe'u-LA.
• הזאת is usually ha-ZOT.
• חשובה begins with ח, a throaty sound that does not exist in standard English. If that is hard at first, an h-like sound is an acceptable beginner approximation.

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

So instead of saying:

• The action is important

Hebrew simply says:

• הפעולה חשובה

When you add הזאת, you get:

• הפעולה הזאת חשובה = This action is important

This is completely normal Hebrew grammar.

In Hebrew, demonstratives like this usually come after the noun.

So:

• הפעולה הזאת = this action

This is different from English, where we say this action.

A useful pattern is:

• ה... הזאת for a feminine singular noun: the ... this
• Literally it looks like the action this, but in natural English it means this action

Because Hebrew typically makes both the noun and the demonstrative definite in this structure.

So:

• פעולה = an action / action
• הפעולה = the action
• הפעולה הזאת = this action

This double definiteness is normal in Hebrew. English does not do this, but Hebrew does.

Because פעולה is a feminine singular noun, and the demonstrative must agree with it.

Here are the singular forms:

• masculine: הזה / זה
• feminine: הזאת / זאת

Since פעולה is feminine, Hebrew uses:

• הפעולה הזאת

If the noun were masculine, you would use:

• הספר הזה = this book

The adjective must agree with the noun in gender and number.

Since פעולה is feminine singular, the adjective also has to be feminine singular:

• חשובה

Compare:

• masculine singular: חשוב
• feminine singular: חשובה

So:

• ספר חשוב = an important book
• פעולה חשובה = an important action

The final -ה is a very common feminine ending for adjectives, though not every feminine word follows this pattern.

In Hebrew, adjectives normally come after the noun they describe.

So:

• פעולה חשובה = important action
• הפעולה הזאת חשובה = this action is important

In this sentence, חשובה is the predicate adjective: it tells you something about הפעולה הזאת.

Hebrew word order here is very natural:

• [the action this] [important]

Yes. הזו and הזאת can both mean this for feminine singular nouns.

So both of these are correct:

• הפעולה הזאת חשובה
• הפעולה הזו חשובה

In many contexts, הזו sounds a bit more common or conversational, while הזאת can sound a little more formal or full, depending on the speaker and context. But both are standard and useful.

The basic noun is:

• פעולה = action / operation / act

With the definite article:

• הפעולה = the action

So the full sentence is built from:

• הפעולה = the action
• הזאת = this
• חשובה = important (feminine)

You would change both the demonstrative and the adjective to masculine forms.

For example:

• הספר הזה חשוב = This book is important

Compare carefully:

Feminine:

• הפעולה הזאת חשובה

Masculine:

• הספר הזה חשוב

So the pattern is:

• feminine singular: ה... הזאת / הזו + adjective in feminine
• masculine singular: ה... הזה + adjective in masculine

In the plural, the demonstrative and adjective also change to match.

For example:

Masculine plural:

• הספרים האלה חשובים = These books are important

Feminine plural:

• הפעולות האלה חשובות = These actions are important

Notice:

• האלה = these
• חשובים = masculine plural important
• חשובות = feminine plural important

So Hebrew agreement is very important: noun, demonstrative, and adjective all match.

In standard Hebrew, that would sound wrong or incomplete.

You normally say:

• הפעולה הזאת

not:

• פעולה הזאת

With this kind of this/that construction, Hebrew usually wants the noun to be definite:

• הפעולה הזאת = this action

So keep the ה on the noun.

It is neutral and completely natural. It works in:

• everyday speech
• writing
• instructions
• workplace contexts
• academic or formal contexts

If you want a slightly more conversational version, many speakers might say:

• הפעולה הזו חשובה

But הפעולה הזאת חשובה is perfectly normal and correct.
