Greek marks possession with the same seven unstressed words it uses for the indirect object. μου, σου, του, της, μας, σας, τους — put one after a noun and it means "my, your, his, her, our, your, their"; put the same word in front of a verb and it means "to me, to you, to him…". Nothing about the word changes. Nothing about the spelling changes. The only difference is where it stands.
The paradigm itself, the fact that these forms never inflect for the thing owned, the obligatory article, the position after the noun and the second accent that a proparoxytone host grows are all set out on possessive determiners, and there is no point repeating them here. What that page does not do — because it is looking at the noun phrase — is confront you with the other job the same words are doing three centimetres to the left. That is what this page is for.
Two jobs, one difference
| Greek | What the clitic is next to | Meaning |
|---|---|---|
| μου έφερε | a verb | he brought me… |
| το βιβλίο μου | a noun | my book |
| της τηλεφώνησα | a verb | I phoned her |
| το γραφείο της | a noun | her office |
| τους άνοιξα | a verb | I opened for them |
| τα παιδιά τους | a noun | their children |
The test is a single question, and it does not involve meaning at all: what kind of word is the clitic leaning on? A clitic has no accent, so it has to attach itself to a stressed neighbour. If that neighbour is a verb, the clitic is an object of that verb. If it is a noun — or an adjective or quantifier inside the same noun phrase, as in το καινούριο μου σπίτι — the clitic is a possessive.
Της τηλεφώνησα από το γραφείο της.
tis tilefónisa apó to ghrafío tis
I phoned her from her office.
One sentence, one person, two της — the first leaning on the verb, the second on the noun. Neither is a repetition of the other and no Greek speaker would hear it as one.
The minimal pairs
This is where the difference stops being an abstraction. Change nothing but the clitic's position and you get two sentences with different meanings, both of them things you might say in a kitchen.
Φέρε μου το βιβλίο που άφησα στο σαλόνι.
fére mu to vivlío pu áfisa sto salóni
Bring me the book I left in the living room.
Φέρε το βιβλίο μου, όχι το δικό σου.
fére to vivlío mu, óchi to dhikó su
Bring my book, not yours.
In the first, μου is behind the imperative φέρε and I am the person being brought something. In the second, μου is behind βιβλίο and I am merely the owner — somebody else may well be the one receiving it. The English translations use two entirely different structures ("bring me the book" versus "bring my book"); the Greek uses one word in two slots.
Δώσε μου το τηλέφωνο, θέλω να πάρω τη μητέρα μου.
dhóse mu to tiléfono, thélo na páro ti mitéra mu
Give me the phone, I want to ring my mother.
Δώσε το τηλέφωνό μου στη Μαρία, θα σε πάρει αυτή.
dhóse to tiléfonó mu sti María, tha se pári aftí
Give my number to Maria — she'll call you.
The written accent is a signal, and it is free
Look carefully at το τηλέφωνο in the first of those two and το τηλέφωνό μου in the second. The noun has grown a second accent in the possessive sentence and not in the other one, and that is not decoration: it is the visible trace of which word the clitic attached to.
The mechanism is on the second accent, and the short version is that a host stressed on its third-from-last syllable needs a supporting accent when an enclitic is added. So the second accent appears exactly when a proparoxytone noun has taken a possessive clitic — which means, in careful writing, you can often see at a glance which reading is intended before you have parsed anything.
Το αυτοκίνητό της είναι παρκαρισμένο απέναντι.
to aftokínitó tis íne parkarizméno apénandi
Her car is parked opposite.
Πες μου το όνομά σου ξανά, το ξέχασα.
pes mu to ónomá su ksaná, to kséchasa
Tell me your name again, I've forgotten it.
That second sentence has both jobs and only one second accent: μου is leaning on the imperative πες, which is a two-syllable word and needs no repair, while σου is leaning on the proparoxytone όνομα, which does. The accent is doing exactly the work the position is doing, and it is doing it for free.
Both at once
Because the two jobs occupy different slots, nothing stops them appearing in the same clause — and they very often do.
Μου έφερε το βιβλίο μου από το γραφείο.
mu éfere to vivlío mu apó to ghrafío
He brought me my book from the office.
Της έδωσα το τηλέφωνό μου αλλά δεν με πήρε ποτέ.
tis édhosa to tiléfonó mu alá dhen me píre poté
I gave her my number but she never rang me.
The second one is worth pausing on. Της and μου are the same kind of word doing the same kind of grammar, and they refer to two different people — she receives, I own. English needs "her" and "my", two visibly different words, to say this. Greek needs two identical-looking clitics in two different positions, and it is never unclear.
Δεν μου το ανέφερε καθόλου, το έμαθα από τον αδερφό του.
dhen mu to anéfere kathólu, to ématha apó ton adherfó tu
He never mentioned it to me — I heard it from his brother.
Why the ambiguity never actually happens
It is reasonable to expect a system this economical to break down somewhere, and worth saying plainly that it does not. A verb and a noun are never in the same slot: the object clitic sits in front of a finite verb (or immediately behind a positive imperative), and the possessive sits inside the noun phrase, behind its noun. There is no configuration where those two positions overlap, so there is no string of Greek where you have to guess.
Three signals settle it, and any one of them is enough:
- A particle in front — δεν, θα, να, ας, μην — guarantees that what follows is the verbal complex, so the clitic is an object. Δεν μου το είπε.
- An article two words back — the clitic is inside a noun phrase, so it is a possessive. το σπίτι μου.
- The second accent on a proparoxytone noun, as above.
The one genuine ambiguity in this corner of the grammar is a different one, and it has nothing to do with position: third-person του and της do not say whether the owner is the subject of the sentence or somebody else, so πήγε στο γραφείο του can be his own office or another man's. That is dealt with on possessive determiners, together with the stressed δικός του that forces the reflexive reading.
Common Mistakes
1. Sticking the possessive onto the verb. The clitic goes behind the thing that is owned, and a finite verb is not it.
❌ Έχασα μου τα κλειδιά και δεν μπορώ να μπω.
Incorrect — a possessive attaches to its noun: Έχασα τα κλειδιά μου.
✅ Έχασα τα κλειδιά μου και δεν μπορώ να μπω στο σπίτι.
échasa ta klidhiá mu ke dhen boró na bo sto spíti
I've lost my keys and I can't get into the house.
2. Producing the right word in the wrong slot. Both of these are correct Greek and they ask for different things; learners who mean the first routinely say the second.
Δείξε μου τις φωτογραφίες από τον γάμο.
dhíkse mu tis fotoghrafíes apó ton ghámo
Show me the photos from the wedding. (clitic on the verb — I am the one being shown, and the photos may be anybody's)
Δείξε τις φωτογραφίες σου στη μητέρα μου.
dhíkse tis fotoghrafíes su sti mitéra mu
Show your photos to my mother. (clitic on the noun — they are your photos, and somebody else is being shown them)
3. Assuming the two clitics in a clause must be the same person. They are independent: one is chosen by the verb, the other by the owner.
Του έδωσα το βιβλίο του πριν φύγει.
tu édhosa to vivlío tu prin fíyi
I gave him his book back before he left. (both clitics are him)
Του έδωσα το βιβλίο μου να το διαβάσει.
tu édhosa to vivlío mu na to dhiavási
I gave him my book to read. (he receives, I own)
Key Takeaways
- The possessive clitics are the indirect-object clitics: μου, σου, του, της, μας, σας, τους, with no change of form whatsoever.
- Position is the whole difference. Leaning on a verb → object ("to me"). Leaning on a noun, adjective or quantifier inside a noun phrase → possessive ("my").
- The two can share a clause and refer to different people: Της έδωσα το τηλέφωνό μου.
- A second accent on a proparoxytone noun (το τηλέφωνό μου, το όνομά σου) is a visible sign that the clitic docked on the noun, not on the verb.
- The system never becomes ambiguous, because the verbal slot and the noun-phrase slot never coincide. A particle (δεν, θα, να) guarantees a verbal reading; a preceding article guarantees a possessive one.
- Decide the job before the form — the form is identical either way, so choosing the word first is what puts it in the wrong place.
