Comparative With πιο | Greek Grammar

There are two ways to say "more X" in Greek, and this page teaches the one you should reach for first: put the little word πιο in front of any adjective. πιο ψηλός (taller), πιο εύκολο (easier), πιο ακριβός (more expensive). It is the Greek equivalent of English more — and, crucially for a beginner, it works with every adjective in the language without exception. Learn it and you can build a comparative for any adjective you know, even one you met five minutes ago. The tidier synthetic form (ψηλότερος) exists too and gets its own page, but πιο is the reliable default, so start here.

πιο + adjective: the reliable default

The recipe could not be simpler: πιο goes directly before the adjective, and the adjective keeps its normal ending. That is the whole rule. English speakers will find this instantly familiar, because more behaves the same way — more expensive, more careful.

Αυτός ο δρόμος είναι πιο σύντομος, θα φτάσουμε πιο γρήγορα.

aftós o dhrómos íne pio síndomos, tha ftásume pio ghríghora

This road is shorter — we'll get there faster.

Το δεύτερο ξενοδοχείο ήταν πιο ακριβό, αλλά και πιο καθαρό.

to dhéftero ksenodhochío ítan pio akrivó, alá ke pio katharó

The second hotel was more expensive, but also cleaner.

Πάρε το άλλο μαχαίρι, είναι πιο κοφτερό.

páre to álo machéri, íne pio kofteró

Take the other knife, it's sharper.

Notice in the first example that πιο can even stack onto an adverb (πιο γρήγορα, "faster") — but its home base is the adjective.

πιο never moves — the adjective still agrees

Here is the point that trips learners up, precisely because English lulls them into thinking it works exactly like more. In English, both the intensifier and the adjective are frozen: she is more tall, they are more tall — nothing changes. In Greek, πιο itself is invariable, but the adjective behind it is still a full-blooded Greek adjective and must agree with its noun in gender, number and case, exactly as it would on its own.

Watch the same adjective, όμορφος, reshape itself while πιο sits perfectly still:

Ο δρόμος της παραλίας είναι πιο όμορφος από τον κεντρικό.

o dhrómos tis paralías íne pio ómorfos apó ton kendrikó

The coast road is prettier than the main one.

Η κόρη τους έγινε πιο όμορφη κι από τη μητέρα της.

i kóri tus éyine pio ómorfi ki apó ti mitéra tis

Their daughter has grown even prettier than her mother.

Το δωμάτιο με θέα είναι πιο ακριβό, αλλά αξίζει.

to dhomátio me théa íne pio akrivó, alá aksízi

The room with a view is more expensive, but it's worth it.

Masculine όμορφος, feminine όμορφη, neuter ακριβό — three endings, one fixed πιο. If you ever catch yourself leaving the adjective in its dictionary form because "πιο already did the work," that is the English habit talking.

💡

Think of πιο as a road sign, not a word that participates in the sentence's grammar. It points at the adjective and says "turn this up," but it carries no gender, number or case of its own. The agreement burden falls entirely on the adjective — so decline the adjective just as you learned to on its own paradigm page.

Saying what you compare to: από + accusative

To add the second half of a comparison — the than part — Greek uses από followed by the accusative:

Η Μαρία είναι πιο δυναμική από όλους στην ομάδα.

i María íne pio dhinamikí apó ólus stin omádha

Maria is more driven than everyone on the team.

Το καλοκαίρι φέτος ήταν πιο ζεστό από πέρσι.

to kalokéri fétos ítan pio zestó apó pérsi

The summer was hotter this year than last.

Two things are worth flagging without going deep, because they have their own pages. First, the pronoun after από goes accusative — από εμένα ("than me"), not από εγώ — a point that catches everyone at first. Second, formal and literary Greek has a rival construction, the genitive of comparison (ψηλότερός μου, "taller than me"), which replaces από entirely. Both the accusative-with-από rule and its genitive alternative are worked out on the object of comparison and the case after comparatives. On this page, just use από + accusative and you will always be understood.

"Less": λιγότερο + adjective

The mirror image of πιο is λιγότερο ("less"), and it behaves the same way — it sits in front of the adjective and stays invariable while the adjective agrees:

Αυτή η άσκηση είναι λιγότερο δύσκολη από την προηγούμενη.

aftí i áskisi íne lighótero dhískoli apó tin proighúmeni

This exercise is less difficult than the previous one.

Προτιμώ ένα λιγότερο ακριβό εστιατόριο για απόψε.

protimó éna lighótero akrivó estiatório ya apópse

I'd rather have a less expensive restaurant for tonight.

💡

Greek, even more than English, prefers to flip a "less X" comparison into a positive one. Rather than λιγότερο ψηλός ("less tall"), a native speaker will usually say πιο κοντός ("shorter"); rather than λιγότερο ακριβό, often just πιο φθηνό ("cheaper"). λιγότερο is perfectly correct and common, but if a plain opposite exists, reaching for it sounds more natural.

"As … as" and "equally": τόσο … όσο, εξίσου

For comparisons of equality — "as tall as," "just as good" — Greek uses the pair τόσο … όσο wrapped around the adjective, most often in a negative ("not as … as"):

Δεν είμαι τόσο ψηλός όσο ο πατέρας μου.

dhen íme tóso psilós óso o patéras mu

I'm not as tall as my father.

Το ταξίδι δεν ήταν τόσο κουραστικό όσο περίμενα.

to taksídhi dhen ítan tóso kurastikó óso perímena

The trip wasn't as tiring as I expected.

When the two things are simply equal, the one-word εξίσου ("equally, just as") does the job, and it links its second term with με ("with"):

Το δεύτερο βιβλίο είναι εξίσου καλό με το πρώτο.

to dhéftero vivlío íne eksísu kaló me to próto

The second book is just as good as the first.

πιο or ψηλότερος? Both, but not together

Greek has a second, tidier comparative: a single word built from the adjective's own stem — ψηλός → ψηλότερος, ακριβός → ακριβότερος. It means exactly the same as πιο + adjective and is slightly more at home in writing. You can use either. The one thing you must never do is combine them: πιο ακριβότερος is a double comparative and is simply wrong, the way more cheaper is wrong in English. Pick one road to the meaning. The synthetic form is laid out on the synthetic comparative in -τερος.

💡

A small but high-frequency catch: a handful of everyday adjectives don't take πιο at all in careful Greek — they have their own irregular comparatives. "Better" is καλύτερος and "bigger" is μεγαλύτερος; the colloquial πιο καλός / πιο μεγάλος is heard in casual speech, but the irregular form is the one to learn and write. They are all collected on the irregular comparatives page.

Common Mistakes

1. Leaving the adjective in its dictionary form. πιο is invariable, but the adjective is not — it must agree with its noun.

❌ Η αδερφή μου είναι πιο ψηλό από εμένα.

Incorrect — the adjective must be feminine to match αδερφή: πιο ψηλή.

✅ Η αδερφή μου είναι πιο ψηλή από εμένα.

i adherfí mu íne pio psilí apó eména

My sister is taller than me.

2. Stacking πιο on top of a -τερος form. Choose one comparative; never both.

❌ Αυτό το κινητό είναι πιο ακριβότερο από το δικό μου.

Incorrect — πιο ακριβό or ακριβότερο, but not both together.

✅ Αυτό το κινητό είναι πιο ακριβό από το δικό μου.

aftó to kinitó íne pio akrivó apó to dhikó mu

This phone is more expensive than mine.

3. Using σαν for "than". After a comparative, "than" is από. σαν means "like/as" and cannot introduce a comparison.

❌ Είναι πιο δυνατός σαν εμένα.

Incorrect — 'than' after a comparative is από, not σαν ('like').

✅ Είναι πιο δυνατός από εμένα.

íne pio dhinatós apó eména

He's stronger than me.

4. Putting πιο after the adjective. πιο always comes before the word it lifts.

❌ Ο καινούριος δρόμος είναι σύντομος πιο.

Incorrect — πιο goes in front of the adjective: πιο σύντομος.

✅ Ο καινούριος δρόμος είναι πιο σύντομος από τον παλιό.

o kenúrios dhrómos íne pio síndomos apó ton palió

The new road is shorter than the old one.

Key Takeaways

The everyday comparative is πιο + adjective: πιο ψηλός, πιο εύκολο, πιο ακριβός. It works with every adjective.
πιο never changes, but the adjective behind it still agrees with its noun in gender, number and case.
Attach the second term with από + accusative (πιο ψηλός από εμένα); the genitive alternative is on the object of comparison.
"Less" is λιγότερο (invariable, adjective agrees); Greek often prefers flipping to the opposite (πιο κοντός over λιγότερο ψηλός).
Equality is τόσο … όσο ("as … as") and εξίσου … με ("just as … as").
πιο and the synthetic -τερος form mean the same thing — use one or the other, never both (×πιο ακριβότερος).
