Greek Words in The Odyssey: Nostos, Xenia and Kleos Explained

Christopher Nolan’s The Odyssey opened in July 2026 to the biggest debut of his career, which means millions of people have just watched Odysseus fight his way home. If you’re one of them, here’s something the film couldn’t show you: the Greek words in The Odyssey that still live on to this day. Three of them, νόστος, ξενία, and κλέος, are still visible in English, and they’re alive in the Modern Greek spoken in Greece today. You’ll also find out what “odyssey” itself means, and how Greeks say the heroes’ names.

A quick heads-up: minor spoilers follow, for both the film and the 2700-year old poem it’s based on.

νόστος (nóstos) — the ache to get home

νόστος means homecoming: the return from a long journey, and everything a person feels while fighting to get there. It’s the engine of The Odyssey. Odysseus turns down immortality with a goddess because it isn’t home, and the poem announces the theme in its opening lines, where he struggles to win “his own life and the homecoming of his companions”.

Ancient Greek had a whole story category built on this word: the νόστοι, the homecoming tales of the heroes after Troy. The Odyssey is the one that survived.

From nostos to nostalgia

Here’s the first place you already know this word. In 1688, a Swiss medical student named Johannes Hofer needed a term for a condition he was seeing in Swiss soldiers stationed abroad: they missed home so badly they stopped eating, weakened, and in some cases died. He built a diagnosis from Greek parts: νόστος, homecoming, plus άλγος, pain. Nostalgia was a disease for about two centuries before it softened into the bittersweet feeling we mean now.

So when the film leaves you a little wistful, the word for that feeling is Odysseus’s word. Homecoming-pain.

Why the Greek word for “delicious” comes from homecoming

This is my favourite fact in the language. The everyday Modern Greek word for “delicious” is νόστιμος (nóstimos), and it comes straight from νόστος. The word originally meant “of the homecoming”, drifted towards “wholesome”, and settled centuries ago on “tasty”.

Think about what greets a returning traveller in the poem. Every safe arrival means a table full of food and wine. The taste of homecoming became the word for taste itself.

Order food anywhere in Greece and you’ll hear it. Νόστιμο! is “delicious!”, and if the cook is really on form, πεντανόστιμο, “five-times delicious”. Every Greek saying it is, etymologically speaking, quoting Homer’s plot.

ξενία (xenía) — the sacred rules of hospitality

ξενία is the ancient Greek guest-code: the mutual obligation between host and stranger. A host fed and sheltered a traveller before asking who they were; the guest, in turn, behaved. The stakes ran far past manners: Zeus himself, under the title Xenios, enforced the code, and mistreating a stranger risked divine payback, partly because the stranger at your door might be a god in disguise.

Once you know the rule, The Odyssey reads differently. The story is a chain of hospitality tests. The Phaeacians pass: they feast Odysseus before asking his name. The Cyclops fails as monstrously as possible, eating his guests instead of feeding them. And the suitors, camped in Odysseus’s hall devouring his stores for years, commit the longest-running ξενία violation in the poem, which is why it treats the bloodbath at the end as justice.

Xenia today: filoxenia

Modern Greece kept the instinct and renamed it. The word now is φιλοξενία (filoxenía), “friendship to the stranger”, and it’s the trait Greeks are proudest of. Being given a free dessert at the end of a meal, or having your neighbour gift you homemade honey an hour after meeting are examples of this concept, three thousand years on. We’ve written a whole guide to filoxenia and the phrases used to welcome you, because you’ll meet it within a day of landing.

Spot the root: ξένος

The root of both words is ξένος (xénos), which means stranger and guest at the same time. The code of ξενία starts from exactly that assumption: a stranger is a guest you haven’t fed yet.

English took the fearful half: xenophobia, fear of the stranger. Greek built something warmer. The Modern Greek word for hotel is ξενοδοχείο (xenodochío), literally “a place that receives strangers”. Book a room in Athens and you’re reading Homer’s vocabulary on the sign above the door.

κλέος (kléos) — glory that outlives you

κλέος is usually translated “glory”, but it’s more precise than that. The word comes from an ancient root meaning “to hear”, the same root that produced the English word “loud”, so κλέος is literally “what others hear about you”: the story of your deeds, still being told after you’re gone. In a world before writing, being talked about was the only immortality on offer.

The two Homeric epics are a debate about this word. Achilles, in the Iliad, is offered the choice between a long quiet life and κλέος, and chooses glory. Odysseus is the counter-argument: the hero who walks away from immortality itself because he’d rather have his νόστος. Nolan filmed the second answer.

The -kles names: Pericles, Sophocles, Heracles

κλέος hides in plain sight at the end of famous Greek names. Pericles is περί + κλέος, “famed all around”. Sophocles is “famed for wisdom”. Heracles is “the glory of Hera”.

These aren’t museum pieces. Περικλής and Ηρακλής are still on Greek ID cards today, and Ηρακλής is also a major football club in Thessaloniki. Naming a baby after two-and-a-half thousand years of κλέος is entirely normal in Greece.

The heroes’ names in Greek, and how to say them today

The names you heard in the cinema are English adaptations. Here’s what they look and sound like in Modern Greek, with what they originally meant.

English	Modern Greek	Sounds like	Meaning
Odysseus	Οδυσσέας	o-thee-SEH-as	Uncertain; see below
Penelope	Πηνελόπη	pee-neh-LO-pee	Debated: linked to πηνέλοψ, a kind of duck, or to πήνη, the thread on a loom
Telemachus	Τηλέμαχος	tee-LEH-ma-hos	“Far fighter”: τηλε (far) + μάχη (battle)

A few things worth noticing. The δ in Οδυσσέας is the soft th of English “this”, not a hard d. Penelope’s possible loom etymology fits a queen who famously weaves and unweaves a shroud to hold off her suitors. And the τηλε in Telemachus is the same “far” that English borrowed for telephone and television — the boy named “far fighter” was born as his father left for a war far away.

All three remain real names in Greece. Meet an Οδυσσέας in Athens and he’ll answer to it at the coffee shop. If the letters themselves are unfamiliar, our introduction to the Greek alphabet gets you reading them in an afternoon.

What does “odyssey” itself mean?

Ὀδύσσεια, the poem’s ancient title, means “the story of Odysseus”. That’s all: the epic is named after the man, not the other way round.

The man’s own name is a genuine puzzle. The poem itself connects it to a verb meaning “to be angry” or “to suffer grief”, a fitting name for a man the gods keep punishing, but modern scholars treat that as folk etymology and consider the name pre-Greek, older than the Greek language’s records themselves.

English turned the title into a common noun for any long, eventful journey. Modern Greek did the same thing: οδύσσεια is what a Greek calls a bureaucratic nightmare or a 14-hour journey with three cancelled connections. Both languages agreed the man’s suffering deserved a word.

If you enjoyed this kind of word history, yamas, the Greek toast, pulls off the same survival act: it literally means “our health” and its root is ancient too.

FAQ

What does nostos mean in The Odyssey? νόστος (nóstos) means homecoming: the return from a long journey. It’s the goal of the entire poem, and the ancient Greeks recognised a whole genre of homecoming stories, the νόστοι, about the heroes returning from Troy. It’s also the root of the English word nostalgia, “homecoming-pain”.

What is xenia and why does it matter in The Odyssey? ξενία (xenía) is the ancient guest-code: hosts owed strangers food, shelter, and protection, with Zeus enforcing the rule. Most of The Odyssey’s episodes are hospitality tests. The Cyclops and the suitors violate ξενία, which is why the poem punishes them.

Is nostalgia a Greek word? Its parts are Greek (νόστος, homecoming, + άλγος, pain), but the word was assembled in 1688 by the Swiss physician Johannes Hofer as a medical diagnosis for severe homesickness. Modern Greek then borrowed it back as νοσταλγία.

Do Greeks today speak the Greek of Homer? No. Modern Greek descends from Homer’s language but has changed enormously across nearly three millennia; Greeks read Homer at school in translation or with heavy notes. Plenty of individual words survived the journey, though, νόστιμος and φιλοξενία among them, which is what this article is about.
