Η τεχνολογία αλλάζει γρήγορα.

Η is the feminine singular definite article, so it means the.

In this sentence, τεχνολογία is a feminine noun, so the article must also be feminine singular: η τεχνολογία = the technology.

A quick note: Η here is capitalized because it is the first word of the sentence. In lowercase, it would be η.

In Greek, every noun has a grammatical gender: masculine, feminine, or neuter. Τεχνολογία happens to be feminine, so it takes the feminine article η.

This is grammatical gender, not biological gender. Many abstract nouns in Greek are feminine.

So:

• η τεχνολογία = the technology

A rough English-style pronunciation is:

ee teh-hnoh-loh-YEE-ah ah-LAH-zee GHREE-ghoh-rah

A few helpful points:

• η sounds like ee
• γ before ρ in γρήγορα is a soft Greek sound that does not exist exactly in English, but many learners start with a sound somewhat like a light gh/y sound
• The stressed syllables are marked by the accent marks:
  • τεχνολογία
  • αλλάζει
  • γρήγορα

Αλλάζει means changes or is changing, depending on context.

It is the 3rd person singular form of the verb αλλάζω = to change.

So αλλάζει can mean:

• he changes
• she changes
• it changes

In this sentence, it means it changes, because the subject is technology.

Because Greek usually does not need subject pronouns when the verb ending already shows the person and number.

So instead of saying it changes, Greek often just says changes, and the subject is understood from the noun already given.

Here:

• Η τεχνολογία = the technology
• αλλάζει = changes / is changing

Greek does have words for he/she/it, but they are often omitted unless needed for emphasis or clarity.

This is the most neutral and natural word order:

• Η τεχνολογία = subject
• αλλάζει = verb
• γρήγορα = adverb

So it follows a pattern similar to English: The technology changes quickly.

Greek word order is more flexible than English, though. You may sometimes see other orders for emphasis, such as:

• Η τεχνολογία γρήγορα αλλάζει
• Γρήγορα αλλάζει η τεχνολογία

But the basic, straightforward version is the one you were given.

Here, γρήγορα is an adverb, meaning quickly.

It tells us how the technology changes.

Compare:

• γρήγορος = quick, fast (masculine adjective)
• γρήγορη = quick, fast (feminine adjective)
• γρήγορο = quick, fast (neuter adjective)
• γρήγορα = quickly / fast (adverb)

So in this sentence, γρήγορα is not describing a noun; it is modifying the verb αλλάζει.

It can mean both, depending on context.

Greek present tense often covers both:

• a general truth or habitual action: changes
• an action happening now: is changing

So Η τεχνολογία αλλάζει γρήγορα can mean:

• Technology changes quickly
• Technology is changing quickly

English chooses between simple present and present continuous more strictly than Greek does.

The accent mark in Greek shows which syllable is stressed when you pronounce the word.

So:

• τεχνολογία
• αλλάζει
• γρήγορα

This is very important in Greek pronunciation. If you stress the wrong syllable, you may sound unnatural or even cause confusion.

Yes, Greek could use plural if the meaning called for it, but in this sentence technology is being used as a general concept, so singular is natural.

• Η τεχνολογία = technology, as a field or general idea
• Οι τεχνολογίες = technologies, meaning different technologies

So this sentence is talking about technology in general, not several separate technologies.

Often, yes.

Greek frequently uses the definite article in places where English may or may not use the.

So Η τεχνολογία αλλάζει γρήγορα can be translated naturally as:

• Technology changes quickly
• The technology changes quickly

In many contexts, English prefers technology without the, even though Greek uses η.

The dictionary forms are:

• η τεχνολογία = technology
• αλλάζω = to change
• γρήγορα = quickly

For verbs, dictionaries usually list the 1st person singular form, so you learn:

• αλλάζω = I change / to change

Then in the sentence it becomes:

• αλλάζει = he/she/it changes

Not literally, but it can feel close in meaning depending on context.

The verb αλλάζει specifically means changes. If you wanted to say evolves, Greek would usually use a different verb, such as εξελίσσεται.

So:

• Η τεχνολογία αλλάζει γρήγορα = Technology changes quickly
• Η τεχνολογία εξελίσσεται γρήγορα = Technology evolves quickly

They are related ideas, but not exactly the same.
