כלכלה מעגלית חשובה לקיימות.

In Hebrew, the present tense often does not use a separate word for is / am / are.

So:

כלכלה מעגלית חשובה לקיימות

literally looks like:

circular economy important for sustainability

but it naturally means:

Circular economy is important for sustainability.

If you wanted to say this in the past or future, Hebrew would usually use forms of להיות (to be).

Because כלכלה is a feminine singular noun, and adjectives in Hebrew must agree with the noun in gender and number.

• כלכלה = feminine singular
• חשובה = feminine singular form of important

Compare:

• masculine singular: חשוב
• feminine singular: חשובה
• masculine plural: חשובים
• feminine plural: חשובות

So חשובה matches כלכלה correctly.

Because in Hebrew, adjectives usually come after the noun they describe.

So:

• כלכלה מעגלית = circular economy
• literally: economy circular

This is the normal Hebrew pattern:

• ספר מעניין = an interesting book
• עיר גדולה = a big city
• כלכלה מעגלית = circular economy

Also, מעגלית agrees with כלכלה in gender and number, so it is feminine singular too.

The prefix ל־ usually means to or for.

Here it means something like for:

• חשובה לקיימות = important for sustainability

In Hebrew, prepositions are often attached directly to the word:

• ל + קיימות = לקיימות

So instead of writing a separate word for for, Hebrew puts it onto the front of the noun.

Not here. In this sentence, קיימות is a singular abstract noun meaning sustainability.

That can be confusing, because ־ות is also a very common feminine plural ending. But Hebrew also uses ־וּת to form abstract nouns, similar to English endings like -ness or -ity.

Examples:

• חשוב = important

• חשיבות = importance

• אפשרי = possible

• אפשרות = possibility / option

• קיים = existing / sustainable in some contexts
• קיימות = sustainability

So here לקיימות means for sustainability, not to sustainabilities or anything plural.

Not necessarily. Hebrew often leaves out the definite article when making a general statement.

So:

• כלכלה מעגלית חשובה לקיימות = a general statement about circular economy

If you were talking about a specific, known circular economy, you could say:

• הכלכלה המעגלית חשובה לקיימות

Notice that if the noun is definite, the adjective describing it is also definite:

• הכלכלה = the economy
• המעגלית = the circular

That matching is very important in Hebrew.

Because the sentence has two different adjective roles:

1. מעגלית is an adjective directly attached to the noun כלכלה

   • כלכלה מעגלית = circular economy

2. חשובה is the predicate adjective

   • it tells you something about כלכלה מעגלית
   • is important

So the structure is:

• כלכלה מעגלית = subject
• חשובה = predicate adjective
• לקיימות = complement of חשובה

A good way to chunk it is:

[כלכלה מעגלית] [חשובה לקיימות]

A simple pronunciation guide is:

kalkalá ma'agalít chashuvá lekayamút

A few notes:

• כלכלה = kal-ka-LA
• מעגלית = ma-a-ga-LIT
• חשובה = cha-shu-VA
• לקיימות = le-ka-ya-MUT

A couple of sound tips:

• ח in חשובה is a throaty sound, often like kh in transliteration
• ע in מעגלית is often very light or almost silent in modern Israeli Hebrew, but it still affects the flow of the word

In a simple present-tense sentence like this, Hebrew normally does not use היא.

So the most natural version is:

כלכלה מעגלית חשובה לקיימות

Adding היא can sound unnecessary, and in many contexts less natural. For a learner, the best rule is:

• in present-tense sentences like X is important / X is big / X is new, usually leave out is

So:

• העיר גדולה = The city is big
• הספר מעניין = The book is interesting
• כלכלה מעגלית חשובה לקיימות = Circular economy is important for sustainability

Yes, but the original order is the most neutral and natural.

Normal order:

כלכלה מעגלית חשובה לקיימות

This is the clearest way to say it.

Hebrew can sometimes move parts around for emphasis, especially in writing or formal speech, but for learners it is best to keep:

• subject
• then predicate
• then any prepositional phrase

So this sentence is a very good model to follow.
