Arunc gunoiul după cină.

Romanian often drops the subject pronoun when it is clear from the verb ending.

Here, arunc already means I throw / I am throwing, so eu is not necessary.

• (eu) arunc = I throw
• (tu) arunci = you throw
• (el/ea) aruncă = he/she throws

You can say Eu arunc gunoiul după cină, but that usually adds emphasis, like I’m the one who throws out the trash.

Arunc is the 1st person singular present tense of the verb a arunca.

So:

• a arunca = to throw
• arunc = I throw / I am throwing

In this sentence, it can express:

• a habit: I throw out the trash after dinner
• or, depending on context, a present action

Romanian present tense often covers both simple present and present continuous ideas from English.

Because -ul is the definite article attached to the end of the noun.

• gunoi = trash / garbage
• gunoiul = the trash / the garbage

Romanian usually puts the at the end of the noun instead of using a separate word.

So:

• băiat = boy
• băiatul = the boy
• gunoi = trash
• gunoiul = the trash

That is just how Romanian normally forms the definite article. Unlike English, Romanian uses a suffix.

For masculine/neuter nouns in the singular, one common definite ending is -ul.

So in this sentence:

• gunoi
  • -ul → gunoiul

This is a very important pattern in Romanian grammar.

Not usually. Gunoi is commonly used like a mass noun, similar to trash or garbage in English.

So gunoiul here usually means:

• the trash
• the garbage
• in natural English, often the trash as a household chore

It does not necessarily mean one specific item.

Here, după means after.

So:

• după cină = after dinner

După is a very common preposition and can also have other uses in other contexts, but in this sentence it simply marks time.

Because meal words are often used without the definite article when talking about them in a general, routine sense.

So:

• după cină = after dinner
• după prânz = after lunch
• după micul dejun = after breakfast

If you said după cina, it would usually need more context, such as:

• după cina de ieri = after yesterday’s dinner
• după cina pregătită de Maria = after the dinner prepared by Maria

So the version without the article is the natural one for a regular daily event.

Yes. Cină is a feminine singular noun.

You can see that from forms like:

• o cină = a dinner
• cina = the dinner

In your sentence, it appears as cină because it is being used in the expression după cină.

The word order is very normal and natural.

• Arunc = verb
• gunoiul = direct object
• după cină = time expression

So the structure is basically:

Verb + object + time

Romanian word order is fairly flexible, though. You could also say:

• După cină, arunc gunoiul.

That puts more focus on after dinner. Both are correct.

Yes, literally it does. But in natural use, it often means I throw out the trash or I take out the trash, depending on context.

Romanian often uses a arunca in places where English might prefer:

• throw out
• take out
• dispose of

So the Romanian is perfectly normal even if the most natural English translation is not word-for-word.

Yes, very naturally.

Arunc gunoiul după cină often sounds like a habitual action:

• I throw out the trash after dinner

Romanian present tense commonly expresses routines without needing an extra word like usually.

If you want to make the habitual meaning even clearer, you could add something like:

• De obicei, arunc gunoiul după cină. = I usually throw out the trash after dinner.

You would add the pronoun:

• Eu arunc gunoiul după cină.

This is grammatically correct, but it sounds more emphatic than the version without eu.

It can suggest contrast, for example:

• Eu arunc gunoiul după cină, nu fratele meu.
• I throw out the trash after dinner, not my brother.

So the pronoun is usually omitted unless you want emphasis, contrast, or clarity.

A learner-friendly pronunciation is roughly:

gu-NOI-ul

The stressed part is noi.

The ending -ul is the attached definite article, and in normal speech the whole word flows together as one unit. A rough English-style approximation would be something like goo-NOY-ool, though Romanian sounds are not exactly the same as English ones.

Yes:

• După cină, arunc gunoiul.

This is completely correct and natural. It slightly highlights the time phrase.

In general:

• Arunc gunoiul după cină. = neutral
• După cină, arunc gunoiul. = a bit more focus on after dinner

Both are good Romanian.
