Few things open doors in Greece faster than a warm, well-placed greeting. Whether you are wandering the whitewashed lanes of Santorini, ordering a frappé in an Athens café, or video-calling a Greek friend, knowing how to say hello in Greek instantly signals respect and curiosity for one of Europe’s oldest living languages. Greek greetings shift depending on who you are speaking to, the time of day, and how formal the situation is, so a single word rarely fits every moment. In this guide you will learn the essential hellos, from the friendly Yassou to the polite Kalimera, complete with Greek script, transliteration, and pronunciation you can actually use. We will also cover graceful goodbyes and the small polite phrases that make you sound less like a tourist and more like a welcome guest.

Why Greek Greetings Are Worth Learning

Modern Greek is spoken by roughly 13 million people, mainly in Greece and Cyprus, and it carries thousands of years of history in every syllable. Greeks are famous for their hospitality, or philoxenia, and a genuine attempt to greet someone in their own language is often met with delight, a bigger smile, and sometimes an extra scoop of dessert. Unlike English, where “hello” covers almost every situation, Greek asks you to make two quick decisions before you speak: how formal you need to be, and what time of day it is. Once you understand those two dials, choosing the right greeting becomes second nature.

The Two Most Important Words: Yassou and Yassas

If you only memorize two greetings, make them these. Yassou (γεια σου) is your everyday, friendly hello for one person you know well or someone your own age. Yassas (γεια σας) is the polite and plural form: use it for elders, strangers, shopkeepers, professionals, or a group of people. The difference comes down to the pronoun sou (informal “you”) versus sas (formal or plural “you”), the same politeness distinction found in French tu and vous.

Both words double as goodbyes, which makes them wonderfully practical. The core word geia (γεια) literally means “health,” so you are essentially wishing someone well every time you say it. A relaxed, extra-friendly version, geia hara (γεια χαρά), roughly means “health and joy” and works well among friends.

Time-of-Day Greetings: Kalimera, Kalispera and More

Greek loves to greet the hours of the day, and these phrases are both friendly and universally polite, so you can use them with anyone. They are built from kalo (good) plus a time word, which makes them easy to remember once you spot the pattern.

Kalimera — Good Morning

Kalimera (καλημέρα) means “good morning” or “good day” and is used from sunrise until roughly noon. It is arguably the most common formal greeting in Greece and sets a cheerful tone. Say it to your hotel receptionist, the baker, or anyone you pass early in the day.

Kalispera — Good Evening

Kalispera (καλησπέρα) means “good evening” and takes over from around midday and into the night. It works perfectly when you enter a restaurant, shop, or someone’s home in the afternoon or evening. Greeks tend to switch to kalispera earlier in the day than English speakers might expect, often right after lunch.

Kalinychta and Kalo Mesimeri

Kalinychta (καληνύχτα), “good night,” is strictly a farewell said when parting for the evening or heading to bed, never a greeting. You may also hear kalo mesimeri (καλό μεσημέρι), “good afternoon,” used around the traditional midday rest.

Casual and Slang Greetings for Friends

Once you are comfortable with the basics, a few relaxed expressions help you blend in with younger Greeks and close friends. Use these only in informal settings.

• Ti kaneis? (Τι κάνεις;) — “How are you?” to one person you know, literally “What are you doing?”
• Ti kanete? (Τι κάνετε;) — the formal or plural version of the same question.
• Ti nea? (Τι νέα;) — “What’s new?”, a breezy way to check in.
• Ela! (Έλα!) — literally “come,” used casually as “hey!” and very commonly to answer the phone among friends.
• Ti leei? (Τι λέει;) — youthful slang for “what’s up?”, literally “what does it say?”

Greeks also have specific ways to answer the phone. Embros (Εμπρός), meaning “forward,” and parakalo (Παρακαλώ), meaning “please,” are the traditional formal options, while a simple Ela works with people you know.

How to Say Goodbye in Greek

Leaving politely matters just as much as arriving. As you already know, yassou and yassas serve as goodbyes too, but Greek offers a few more graceful options for parting ways.

Polite Phrases to Pair With Your Hello

A greeting rarely travels alone. These small courtesies turn a simple hello into a real interaction and show genuine respect.

• Parakalo (Παρακαλώ) — “please,” and also “you’re welcome.”
• Efcharisto (Ευχαριστώ) — “thank you”; add poly (πολύ) for “thank you very much.”
• Signomi (Συγγνώμη) — “excuse me” or “sorry,” useful for getting attention politely.
• Ne (Ναι) — “yes,” which confusingly sounds like the English “nay,” so listen carefully.
• Ochi (Όχι) — “no.”
• Milate anglika? (Μιλάτε αγγλικά;) — “Do you speak English?”, a courteous ice-breaker.

Pronunciation Tips for the Greek Alphabet

Greek pronunciation is refreshingly consistent once you learn a few sounds, and the Greek alphabet is worth studying because it unlocks reading signs and menus. A couple of letters trip up beginners. The gamma (γ) is a soft, throaty sound somewhere between a “y” and a gentle “g,” which is why geia sounds close to “ya.” The delta (δ) is pronounced like the “th” in “this,” not a hard “d.” The chi (χ), as in kalinychta, is a raspy “kh” from the back of the throat, similar to the “ch” in the Scottish “loch.”

Stress placement is crucial in Greek and is always marked with an accent in written text, such as the accent over the έ in καλημέρα. Put the emphasis on the wrong syllable and a word can become hard to understand, so paying attention to those little marks pays off quickly.

Greetings Around the World

Learning to greet people is one of the most rewarding first steps in any language, and every culture handles it a little differently. If Greek has sparked your curiosity, you may enjoy exploring Arabic greetings and farewells or discovering how to say good luck in different ways across languages. Building a small collection of greetings from around the world is a fun way to keep your language-learning momentum going, and the history of Modern Greek offers fascinating context for why Greek greetings sound the way they do.

Frequently Asked Questions

How do you say hello in Greek?

The most common way to say hello in Greek is yassou (γεια σου) for one person you know, or yassas (γεια σας) for a group or in a formal setting. Both come from geia, meaning “health,” and can also mean goodbye.

What is the difference between Yassou and Yassas?

Yassou is informal and singular, used with friends, peers, and children. Yassas is formal or plural, used with elders, strangers, professionals, and groups of people. Choosing the right one shows respect and awareness of Greek etiquette.

When do you use Kalimera and Kalispera?

Use kalimera (good morning) from sunrise until around noon, and kalispera (good evening) from midday into the night. Both are polite and appropriate in almost any situation, formal or casual.

Is Kalinychta a greeting or a goodbye?

Kalinychta (good night) is only a farewell. You say it when leaving in the evening or before going to bed, never when arriving somewhere.

How do you answer the phone in Greek?

Formally, Greeks answer with embros (εμπρός), meaning “forward,” or parakalo (παρακαλώ), meaning “please.” Among friends, a casual ela (έλα), meaning “hey,” is very common.

You can say yassou or yassas, the more final antio (αντίο), or the casual ta leme (τα λέμε), meaning “we’ll talk.” For someone setting off on a journey, sto kalo (στο καλό), “go well,” is a warm choice.
