Η εξουσία αλλάζει τους ανθρώπους.

A good approximation is:

ee ex-oo-SEE-a al-LA-zee toos an-THRO-poos

A few useful notes:

• Η sounds like ee
• θ in ανθρώπους sounds like th in think
• the stressed syllables are marked by the accents:
  • εξουσία
  • αλλάζει
  • ανθρώπους

So the rhythm is roughly:

ee ex-oo-SEE-a al-LA-zee toos an-THRO-poos

Word by word:

• Η = the for a feminine singular noun
• εξουσία = power or authority
• αλλάζει = changes
• τους = the for a masculine plural noun in the accusative
• ανθρώπους = people / humans in the accusative plural

So grammatically:

• Η εξουσία is the subject
• αλλάζει is the verb
• τους ανθρώπους is the direct object

In Greek, every noun has a grammatical gender: masculine, feminine, or neuter. Εξουσία is a feminine noun, so it takes the feminine singular article η.

That does not mean power is biologically female. It is just a grammar category.

A learner usually memorizes a noun together with its article:

• η εξουσία
• ο άνθρωπος
• το παιδί

That makes it easier to remember gender correctly.

Greek uses the definite article much more often than English, especially with abstract nouns and general statements.

So Η εξουσία αλλάζει τους ανθρώπους is perfectly natural Greek for a general truth like Power changes people.

In English, adding the would often sound more specific, but in Greek the article does not always make it specific in the same way.

Αλλάζει is the third person singular present form of the verb αλλάζω, meaning to change.

So:

• αλλάζω = I change
• αλλάζεις = you change
• αλλάζει = he/she/it changes

Here it matches the subject η εξουσία, which is singular.

Because the verb agrees with the subject, not with the object.

In this sentence:

• Η εξουσία = subject, singular
• τους ανθρώπους = object, plural

So the verb must be singular:

• Η εξουσία αλλάζει...

This is the same basic rule as in English:

• Power changes people
• not Power change people

Because τους ανθρώπους is the direct object of the verb, so Greek uses the accusative plural.

Compare:

• οι άνθρωποι = the people as subject
• τους ανθρώπους = the people as object

Examples:

• Οι άνθρωποι αλλάζουν = People change
• Η εξουσία αλλάζει τους ανθρώπους = Power changes people

So the ending and the article change because the noun has a different job in the sentence.

Here, τους means the.

Greek τους can be different things in different contexts:

• τους ανθρώπους = the people
• τους μιλάω = I speak to them
• το σπίτι τους = their house

So τους is not always the same word in function. In this sentence, because it comes right before ανθρώπους, it is the masculine plural accusative article.

It can mean both, depending on context.

Common meanings include:

• power
• authority
• control

In this sentence, power is probably the most natural translation. But the Greek word carries the idea of having authority or power over others, not just physical strength.

So it is not exactly the same as δύναμη, which often means strength or force.

Yes. Greek word order is more flexible than English because case endings help show who is doing what.

The neutral, straightforward version is:

• Η εξουσία αλλάζει τους ανθρώπους

But other orders are possible for emphasis, such as putting τους ανθρώπους earlier if you want to highlight people.

Even so, the original order is the most natural one for a simple statement.

In this sentence, it is understood as a general statement:

• Power changes people

Greek present tense can often correspond to either English simple present or present continuous, depending on context. Here the meaning is habitual or general, so changes is the best match.

If the context were about something happening right now, the same form could sometimes be translated as is changing. But in this sentence, the general meaning is the natural one.
