În dormitor, becul este stricat și nu mai avem lumină.

Because Romanian often puts the definite article at the end of the noun, not before it like English the.

• bec = bulb / a bulb
• becul = the bulb

So becul este stricat means the bulb is broken.

This is one of the first big differences English speakers notice in Romanian:

• băiat = boy
• băiatul = the boy
• dormitor = bedroom
• dormitorul = the bedroom

Both can exist, but they are used a little differently.

• În dormitor = in the bedroom in a general location sense
• În dormitorul... usually needs something more after it, such as:
  • în dormitorul meu = in my bedroom
  • în dormitorul casei = in the bedroom of the house

Romanian often uses the noun without the definite article after prepositions when the place is understood generally:

• în casă = in the house / at home
• la școală = at school
• în dormitor = in the bedroom

So În dormitor, becul este stricat... sounds natural.

Este stricat means is broken, is faulty, or doesn’t work.

The adjective stricat comes from the verb a strica = to break / to spoil / to damage.

With objects, stricat often means something is not functioning properly:

• Telefonul este stricat. = The phone is broken.
• Mașina de spălat este stricată. = The washing machine is broken.

Here:

• becul este stricat = the bulb is broken / the bulb doesn’t work

Because becul is a masculine singular noun, the adjective is stricat. Compare:

• masculine singular: stricat
• feminine singular: stricată
• masculine plural: stricați
• feminine plural: stricate

Yes. That is very common.

• este = full form of is
• e = shorter spoken form

So both are correct:

• Becul este stricat.
• Becul e stricat.

In everyday speech, e is extremely common. Este may sound slightly more careful or formal.

In this sentence, nu mai means no longer / not anymore.

So:

• avem lumină = we have light
• nu mai avem lumină = we no longer have light / we don’t have light anymore

This is a very common Romanian pattern:

• Mai am cafea. = I still have coffee.
• Nu mai am cafea. = I don’t have coffee anymore.
• Mai vine. = He/She is still coming.
• Nu mai vine. = He/She isn’t coming anymore.

So mai often adds the idea of continuation, and with nu, it becomes the idea that something has stopped.

Romanian often expresses this idea with a avea (to have), just like English sometimes does in sentences such as we have no power or we have no light.

• avem lumină = we have light
• nu mai avem lumină = we no longer have light

You could also hear other ways to say similar things, for example:

• nu este lumină = there is no light
• s-a luat curentul = the power went out
• nu avem curent = we don’t have electricity

But in this sentence, nu mai avem lumină is very natural and idiomatic.

Because lumină here refers to light in a general, uncountable sense, not the specific light as a single object.

Compare:

• Avem lumină. = We have light.
• Nu mai avem lumină. = We don’t have light anymore.

This is similar to English using an uncountable noun:

• We have water.
• We need electricity.
• There is light.

If you said lumina, that would mean the light, usually something more specific:

• Lumina este aprinsă. = The light is on.
• Stinge lumina. = Turn off the light.

So in your sentence, lumină is the natural choice.

Because avem means we have.

The sentence is speaking from the perspective of we:

• nu mai avem lumină = we no longer have light

This could refer to:

• the speaker and another person
• the people living in the home
• the household in general

The verb comes from a avea = to have.

Present tense:

• am = I have
• ai = you have
• are = he/she has
• avem = we have
• aveți = you all / you formal have
• au = they have

Și means and.

It connects the two parts of the sentence:

• becul este stricat = the bulb is broken
• nu mai avem lumină = we no longer have light

So:

• becul este stricat și nu mai avem lumină
  = the bulb is broken and we don’t have light anymore

Romanian și is extremely common and works much like English and.

Because În dormitor is placed at the beginning as a setting or scene marker: In the bedroom.

The comma helps separate that introductory location phrase from the main statement:

• În dormitor, becul este stricat...

It is similar to English:

• In the bedroom, the bulb is broken...

In short sentences, Romanian punctuation can sometimes vary a little, but the comma here is perfectly natural and helps clarity.

Not exactly.

• bec = light bulb
• lampă = lamp

So:

• becul este stricat = the bulb is broken
• lampa este stricată = the lamp is broken

If the problem is specifically the bulb, bec is the right word. If the whole lamp or fixture is broken, lampă would be better.

A rough English-friendly guide is:

în dormiTOR, BEcul ESte striKAT shi nu mai aVEM lumiNĂ

A few helpful pronunciation points:

• â / î = a central vowel with no exact English equivalent
  
  • În sounds roughly like a short, tight vowel, not like English in
• c in becul is a hard k sound
• ș in și sounds like English sh
• final ă in lumină is a short neutral vowel, like the a in sofa

Stress:

• dorMItor? Actually the natural stress is dormiTOR
• BEcul
• ESte
• striCAT
• aVEM
• lumiNĂ

Yes. The original sentence is already natural, but Romanian speakers might also say:

• În dormitor, becul e stricat și nu mai avem lumină.
• În dormitor, nu mai avem lumină; becul e stricat.
• În dormitor s-a stricat becul și nu mai avem lumină.

These all mean roughly the same thing, but the focus changes slightly:

• becul este stricat focuses on the bulb’s condition
• s-a stricat becul focuses on the event: the bulb broke / stopped working

So your original sentence is correct and natural; these are just common alternatives.
