Plimb câinele în parc.

Because Romanian often drops the subject pronoun when the verb ending already shows who is doing the action.

• plimb = I walk / I am walking / I take for a walk
• so eu is understood

You can add eu if you want emphasis:

• Eu plimb câinele în parc. = I’m the one walking the dog in the park.

Plimb is the 1st person singular present form of a plimba.

In this sentence, it means something like:

• I walk the dog
• I’m walking the dog
• I’m taking the dog for a walk

This is a good example of a verb that works a bit differently from English: Romanian a plimba can be transitive, so you can directly walk someone/something.

This is a very common question.

• Plimb câinele = I walk the dog / I take the dog for a walk
• Mă plimb = I walk / I take a walk / I’m out walking

So:

• Plimb câinele în parc. = I’m walking the dog in the park.
• Mă plimb în parc. = I’m walking in the park.

The reflexive mă changes the meaning from walking someone/something else to walking yourself.

Because Romanian usually puts the definite article at the end of the noun, not as a separate word in front.

• câine = dog
• câinele = the dog

So -le here is part of saying the.

Because câinele is the correct form for a direct object here.

In this sentence, the dog is what is being walked, so it is in the accusative (which often looks the same as the nominative in Romanian).

• câinele = nominative/accusative definite form
• câinelui = dative/genitive form, used in meanings like to the dog or of the dog

So:

• Plimb câinele = correct
• Plimb câinelui = not correct here

Romanian often uses pe with specific animate direct objects, especially people. With animals, usage is less strict and depends more on style, emphasis, and how personal the animal feels in context.

So:

• Plimb câinele = completely normal
• Îl plimb pe câine = also possible, with more emphasis on the dog

For a learner, the important point is: without pe is natural here.

Because Romanian often uses a bare noun after a preposition when talking about a common place or setting.

So:

• în parc = in the park / at the park

Even though English often wants the, Romanian does not always use the definite article in these location phrases.

If you want to make it more clearly specific, you can say something like:

• în parcul central = in the central park
• în parcul din centru = in the park downtown / in the park in the center

Both can exist, but they are not exactly the same.

• în parc = in the park, focusing on being inside the park as the location
• la parc = more like at the park or sometimes to the park in everyday speech

In Plimb câinele în parc, în fits well because it tells you where the action happens.

Yes. Romanian word order is fairly flexible.

The neutral order here is:

• Plimb câinele în parc.

But other orders are possible for emphasis:

• În parc plimb câinele. = emphasizes where
• Câinele îl plimb în parc. = emphasizes the dog

So the original sentence is the most straightforward, but not the only possible order.

Yes, plimb is present tense.

Like English present forms, Romanian present can mean either:

• something happening now
• something habitual / regular

So Plimb câinele în parc could mean:

• I’m walking the dog in the park
  or
• I walk the dog in the park

Context tells you which one is meant.

â and î represent the same sound in modern Romanian.

• câinele
• în

That sound does not have a perfect English equivalent. It is a close central vowel, written /ɨ/.

A useful beginner point:

• î is normally used at the beginning or end of a word
• â is normally used inside a word

So:

• în starts with the sound → î
• câinele has it inside the word → â

Yes, Romanian nouns have grammatical gender.

• câine is masculine
• parc is neuter

Romanian neuter is special: in the singular, it behaves like masculine, and in the plural, like feminine.

That matters for articles and adjectives:

• un câine / câinele
• un parc / parcul

In this sentence, you mainly see the effect in câinele, where the definite article is attached to the noun.
