Η αλλαγή προκαλεί ανησυχία.

No. Greek capital Η is not the English H.

In this sentence, Η is the capital form of η, the feminine singular definite article, meaning the.

It is pronounced ee, not h.

So Η αλλαγή means the change.

Because αλλαγή is a feminine singular noun in Greek.

Greek articles agree with the noun in:

• gender
• number
• case

So:

• η αλλαγή = the change
• η shows that the noun is feminine, singular, and here nominative

English only has one definite article, the, but Greek has different forms depending on the noun.

Προκαλεί is the 3rd person singular present tense form of the verb προκαλώ.

So:

• προκαλώ = I cause / provoke
• προκαλεί = he/she/it causes or is causing

Since the subject is Η αλλαγή (the change), which is singular, the verb is also singular:

• Η αλλαγή προκαλεί ... = The change causes ...

In this sentence:

• η αλλαγή is the subject, so it is in the nominative
• ανησυχία is the direct object, so it is in the accusative

A useful thing to notice is that with nouns like ανησυχία, the bare noun form can look the same in nominative and accusative singular.

If you added the article, the difference would be clearer:

• η ανησυχία = nominative
• την ανησυχία = accusative

Here there is no article before ανησυχία, so you identify its role from the verb and sentence structure.

Because Greek often leaves a noun without an article when it is meant in a general or indefinite sense.

So ανησυχία here means something like:

• concern
• worry
• anxiety

This is very natural Greek.

If you said την ανησυχία, that would mean the concern/anxiety, referring to something specific.

So:

• προκαλεί ανησυχία = causes concern
• προκαλεί την ανησυχία = causes the concern or refers to a specific concern

Yes, very natural.

It is a common formal or neutral way to say:

• causes concern
• raises concern
• creates worry

You will often see this kind of phrase in:

• news
• politics
• official statements
• serious discussions

So the sentence sounds normal and idiomatic, not word-for-word awkward Greek.

Yes. Greek word order is more flexible than English.

The neutral order here is:

• Η αλλαγή προκαλεί ανησυχία.
• The change causes concern.

But Greek can move words for emphasis. For example:

• Ανησυχία προκαλεί η αλλαγή.

That still means basically the same thing, but it puts more focus on ανησυχία (concern).

So the original sentence is the most straightforward, neutral version.

A rough pronunciation is:

ee al-la-YEE pro-ka-LEE a-ni-see-HEE-a

A few notes:

• Η = ee
• αλλαγή is stressed on the last syllable
• προκαλεί is stressed on the last syllable
• ανησυχία is stressed on -χί-

The written accents show which syllable gets the stress:

• αλλαγή
• προκαλεί
• ανησυχία

Also, Greek χ is not exactly English h. It is a Greek sound, softer and more forward in the mouth.

It can cover a range depending on context.

Ανησυχία can mean:

• worry
• concern
• uneasiness
• anxiety

In this sentence, the most natural English choice is usually concern or worry, because the phrase προκαλεί ανησυχία is often used in a general, not necessarily clinical, sense.

So although anxiety is possible in some contexts, concern is often the best fit here.
