Vecinul meu locuiește la etajul doi.

Romanian often attaches the definite article to the end of the noun, not as a separate word like the in English.

• vecin = neighbor (indefinite, a neighbor)
• vecinul = the neighbor (definite, the specific one)

So vecinul meu literally means the neighbor of mine / my neighbor.

In Romanian, possessive adjectives usually follow the noun they modify:

• fratele meu = my brother
• cartea ta = your book
• vecinul meu = my neighbor

So the normal pattern is noun + possessive (not possessive + noun, as in English).

Meu agrees in gender and number with the noun vecinul.

• vecinul is masculine singular → meu (masculine singular)
• If the noun were feminine singular, you’d use mea:
  • vecina mea = my (female) neighbor

Other examples:

• fratele meu (my brother) – masculine → meu
• sora mea (my sister) – feminine → mea

Normally, no. The natural, standard order is vecinul meu.

You can place the possessive before the noun in certain emphatic or poetic structures with a form like al meu:

• vecinul meu = my neighbor (neutral)
• al meu vecin = my neighbor (very emphatic, stylized, uncommon in everyday speech)

For everyday Romanian, stick to vecinul meu.

Locuiește is:

• the 3rd person singular (he/she)
• present tense
• of the verb a locui (to live, to reside)

Conjugation (present tense):

• eu locuiesc – I live
• tu locuiești – you live (sg.)
• el/ea locuiește – he/she lives
• noi locuim – we live
• voi locuiți – you live (pl.)
• ei/ele locuiesc – they live

So Vecinul meu locuiește… = My neighbor lives…

Romanian has several verbs that can translate as to live:

• a locui → to live/reside (at an address, in a place)

  • locuiește la etajul doi = he/she lives (resides) on the second floor

• a trăi → to live (to be alive; to experience life)

  • El trăiește încă. = He is still alive.
  • Trăiește în România. can also mean lives (as in resides) in Romania, but it’s more general.

• a sta (colloquial) → to stay / to live

  • El stă la etajul doi. = He lives on the second floor (everyday, informal speech)

In a neutral, careful sentence about residence at an address, a locui is the most precise choice.

For floors of a building, Romanian uses la:

• la etajul doi = on the second floor
• la parter = on the ground floor
• la etajul trei = on the third floor

La is very flexible; here it’s somewhat like English at / on combined.
Using pe or în with etajul for this meaning would sound unnatural. So the set expression is la + etajul + number.

As with vecin / vecinul, the -ul at the end is the definite article:

• etaj = floor, story (indefinite)
• etajul = the floor (definite)

So:

• etajul doi = the second floor
• un etaj = a floor
• pe etaj is unusual; you typically say la etajul doi.

Romanian has gendered forms of the number 2:

• doi – used with masculine (and neuter in the singular/plural pattern) nouns
• două – used with feminine nouns

Etajul is masculine → doi.
Examples:

• doi băieți = two boys (masc.)
• două fete = two girls (fem.)
• etajul doi = the second floor (masc.)

In Romanian:

• parter = ground floor
• etajul unu (or etajul întâi) = first floor above ground
• etajul doi = second floor above ground

So in many European systems:

• ground floor → parter
• 1st floor above ground → etajul unu / întâi
• 2nd floor above ground → etajul doi

If you’re thinking in American terms:

• parter ≈ 1st floor (US)
• etajul întâi ≈ 2nd floor (US)
• etajul doi ≈ 3rd floor (US)

Yes, but there’s a nuance:

• etajul doi – uses a cardinal number (literally “the floor two”); this is very common and perfectly natural in everyday speech.
• etajul al doilea – uses an ordinal number (“the second floor” in strictly grammatical terms); sounds a bit more formal or explicit, often in more careful or official language.

Both are correct; etajul doi is more frequent in casual conversation.

Pronunciation (approximate, with English hints):

• lo – like lo in lotion
• cu – like coo in cool (but shorter)
• ie – a glide, roughly ye in yes
• ște – ș is like sh in ship; te like te in ten

So roughly: lo‑koo‑YEH‑shteh

Special letter:

• ș = sh (as in shop)

You need to make both the noun and the verb plural, and adjust the possessive:

• Singular: Vecinul meu locuiește la etajul doi.

  • my neighbor lives…

• Plural: Vecinii mei locuiesc la etajul doi.

  • vecinii = the neighbors (plural definite of vecin)
  • mei = my (masculine plural)
  • locuiesc = they live

So: Vecinii mei locuiesc la etajul doi. = My neighbors live on the second floor.
