Declining Proper Nouns and Names | Romanian Grammar

A proper noun — a person's name, a city, a country — still has to slot into Romanian's case system: you need to say "Maria's house", "I told Andrei", "the centre of Bucharest". The surprise for an English speaker is that how a name declines depends on what kind of name it is, and the divides are sharp. Feminine first names inflect like ordinary feminine nouns, taking a real suffix. Masculine first names don't inflect at all — they stand still while the little word lui is placed in front. City names go a third way, fastening an enclitic article to themselves. This page maps the whole behaviour of names as nouns; the genitive lui page zooms in on the possessive mechanics, while here we cover names across all their roles — subject, object, possessor, recipient, and address.

💡

Three name types, three strategies. Feminine first names: suffix the genitive-dative (Maria → Mariei). Masculine first names: invariable + proclitic lui (lui Ion). City names: enclitic genitive on the name itself (Bucureștiului), never lui. Pick the strategy by the name, not by the sentence.

Names as subjects and objects: no change

In the nominative (subject) and accusative (direct object), names look exactly like their dictionary form — Romanian does not inflect them for these roles. The only thing to watch is that a personal direct object usually takes the marker pe.

Maria a venit, dar Ion a rămas acasă.

Maria came, but Ion stayed home. (both names bare as subjects)

Am întâlnit-o pe Maria în piață.

I ran into Maria at the market. (pe Maria — personal direct object)

L-am văzut pe Andrei la stația de autobuz.

I saw Andrei at the bus stop.

The work begins only when a name becomes a possessor ("Maria's…") or a recipient ("to Ion") — that is, when it needs the genitive-dative.

Feminine names: the suffixed genitive-dative

Feminine names ending in -a behave like ordinary feminine nouns: they take the genitive-dative suffix -ei (the final -a is replaced by -ei). This single form covers both "of Maria" (genitive) and "to Maria" (dative).

Name	Genitive-dative	"of / to …"
Maria	Mariei	of / to Maria
Ana	Anei	of / to Ana
Ioana	Ioanei	of / to Ioana
Elena	Elenei	of / to Elena

Casa Mariei e chiar lângă a noastră.

Maria's house is right next to ours. (Mariei — genitive)

I-am dat cheile Anei înainte să plec.

I gave Ana the keys before I left. (Anei — dative, 'to Ana')

Numărul Elenei nu mai e valabil.

Elena's number is no longer in service.

A feminine name that does not end in -a — Carmen, Ingrid, Astrid — has no native ending to attach -ei to, so it borrows the masculine strategy and uses lui: lui Carmen, lui Ingrid. The suffix needs a Romanian-style -a tail; without one, the name freezes and lui steps in. (Names that do end in -a, like Mariana or Ioana, suffix normally: Marianei, Ioanei.)

Telefonul lui Carmen a sunat în mijlocul ședinței.

Carmen's phone rang in the middle of the meeting. (Carmen doesn't end in -a → lui)

Masculine names: the proclitic lui

Masculine first names do not inflect for the genitive-dative at all. The invariable word lui is placed directly in front of the unchanged name, and lui Ion covers both "of Ion" and "to Ion". This is the one preposed article in the whole language — every other Romanian article clings to the back of its word.

Cartea lui Ion e pe noptieră.

Ion's book is on the nightstand. (genitive)

I-am spus lui Mihai să nu întârzie.

I told Mihai not to be late. (dative — 'to Mihai')

Părinții lui Alexandru s-au mutat la țară.

Alexandru's parents moved to the countryside.

Crucially, lui never agrees with anything: cartea lui Ion, cărțile lui Ion, casa lui Ion — the possessed noun changes, lui Ion stays frozen. That invariability is what makes it so easy to spot once you stop expecting the name itself to inflect.

💡

Resist the urge to fasten an article to a masculine name to show possession. ~~Ionul~~ for "Ion's" does not exist — possession is lui Ion, always with the name untouched. The only ending a masculine name takes is the vocative (Ioane!), never a genitive suffix.

Surnames and foreign names

When you have a full name or a foreign name, the lui strategy generalizes neatly: lui sits in front of the whole unit, which stays uninflected. This is why lui is so handy — it lets Romanian assign a genitive to names it could never inflect, including foreign ones of either gender.

Filmele lui Quentin Tarantino sunt foarte violente.

Quentin Tarantino's films are very violent.

Am citit ultimul roman al lui Mircea Cărtărescu.

I read Mircea Cărtărescu's latest novel. (full Romanian name behind lui)

Discursul lui Mihaela Popescu a fost foarte bine primit.

Mihaela Popescu's speech was very well received. (full feminine name → lui, since the surname blocks the suffix)

Note that with a full feminine name (first + surname), the suffix can't ride on the first name in the middle of the phrase, so lui takes over: romanul lui Mihaela Popescu, not ~~romanul Mihaelei Popescu~~ as a unit. The bare first name alone still suffixes (romanul Mihaelei), but the moment a surname follows, lui governs the whole block.

Place names

City names take a third route. They form the genitive by adding the enclitic article to themselves — exactly like a common noun — and they never use lui, which is reserved for personal names. București → Bucureștiului ("of Bucharest"), Cluj → Clujului, Iași → Iașiului.

Centrul Bucureștiului s-a aglomerat foarte tare.

The centre of Bucharest has become very crowded. (Bucureștiului — enclitic genitive)

Primarul Clujului a anunțat un nou proiect.

The mayor of Cluj announced a new project.

Country names that already end in -a function as inherently definite (România, Franța, Italia) and form the genitive with the feminine -ei suffix, like any -a feminine: România → României, Franța → Franței.

Capitala României este București.

The capital of Romania is Bucharest. (României — genitive of România)

Echipa Franței a câștigat meciul.

France's team won the match.

Used as plain destinations after a preposition, place names stay bare: în România, la București, la Cluj — no article, no lui, because prepositions of motion/location govern the bare form.

M-am mutat la București acum doi ani.

I moved to Bucharest two years ago. (bare after la)

The vocative of names

Names can also be called out, and then they take the vocative endings covered in forming the vocative: masculine -e (Ion → Ioane!), feminine -o (Maria → Mario!) or, increasingly, the plain nominative (Maria!). The vocative is the only suffix a masculine name accepts — it never inflects for the genitive, but it does inflect for address.

Ioane, te caută cineva la ușă!

John, someone's at the door for you! (vocative)

Common Mistakes

❌ cartea Ionului

Incorrect — masculine names don't take the enclitic genitive; use lui in front: cartea lui Ion.

✅ cartea lui Ion

Ion's book

❌ casa lui Maria

Incorrect — a feminine name ending in -a takes the suffix, not lui: casa Mariei.

✅ casa Mariei

Maria's house

❌ centrul lui București

Incorrect — lui is for personal names only; cities take the enclitic genitive: centrul Bucureștiului.

✅ centrul Bucureștiului

the centre of Bucharest

❌ Mariaei / Mariai

Incorrect spelling — the genitive-dative of Maria is Mariei (final -a replaced by -ei).

✅ Mariei

of / to Maria

❌ casa de Ion / casa Ion's

Incorrect — Romanian has no 'of'-word and no apostrophe-s; possession is lui + name: casa lui Ion.

✅ casa lui Ion

Ion's house

Key Takeaways

Names are bare as subjects and objects (with pe on personal objects); inflection only kicks in for the genitive-dative.
Feminine names in -a: suffix -ei (Maria → Mariei). Feminine names without -a, and full names with a surname, borrow lui.
Masculine names: invariable, with proclitic lui in front (lui Ion) — Romanian's only preposed article; the name never takes a genitive suffix.
City names: enclitic genitive on themselves (Bucureștiului), never lui; -a country names suffix -ei (României).
The only suffix a masculine name accepts is the vocative (Ioane!).
