Vedem avionul.

Vedem is the 1st person plural present-tense form of the verb a vedea (to see).

So it means we see.

A few present-tense forms of a vedea are:

• eu văd = I see
• tu vezi = you see
• el/ea vede = he/she sees
• noi vedem = we see
• voi vedeți = you all see
• ei/ele văd = they see

Romanian often leaves out subject pronouns when they are already clear from the verb ending.

So:

• Vedem avionul. = We see the plane.
• Noi vedem avionul. also means We see the plane, but noi is usually added only for emphasis or contrast.

For example:

• Noi vedem avionul, ei văd trenul.
  = We see the plane, they see the train.

Because -ul is the definite article in Romanian for many masculine and neuter singular nouns.

So:

• avion = a plane
• avionul = the plane

Unlike English, Romanian usually puts the definite article at the end of the noun, not before it.

More examples:

• băiat = boy → băiatul = the boy
• copac = tree → copacul = the tree

Avion is a neuter noun in Romanian.

Romanian neuter nouns behave:

• like masculine in the singular
• like feminine in the plural

So in the singular you get:

• un avion = a plane
• avionul = the plane

And in the plural:

• două avioane = two planes
• avioanele = the planes

Because Romanian usually uses an enclitic definite article—that means the article is attached to the end of the noun.

So English:

• the plane

Romanian:

• avionul

This is one of the big differences between Romanian and English.

The most neutral word order in Romanian is usually Verb + Object here, especially when the subject is omitted:

• Vedem avionul.

You can change word order in Romanian, but that usually changes the focus or emphasis.

For example:

• Avionul îl vedem. = It’s the plane that we see. / The plane, we see it.

So Vedem avionul is the normal, straightforward version.

Yes, absolutely.

• Vedem avionul. = neutral, natural
• Noi vedem avionul. = correct, but with extra emphasis on we

A native speaker often omits noi unless there is a reason to stress it.

Romanian often uses pe before a direct object when it refers to a person or a strongly specific/animate being.

But avionul is an inanimate thing, so normally you do not use pe.

Compare:

• Vedem avionul. = We see the plane.
• Vedem băiatul. can occur, but with people Romanian very often uses
  Îl vedem pe băiat. = We see the boy.

So in your sentence, no pe is needed.

A simple English-friendly approximation is:

veh-DEM ah-vyo-NOOL

A few details:

• vedem has stress on the second syllable: ve-DEM
• avionul has stress on -o-: a-vi-O-nul
• the final -ul is part of the definite article

The Romanian e is usually a clear eh sound, and v is like English v.

On its own, Vedem avionul is normally understood as present tense:

• We see the plane
• sometimes also We are seeing the plane, depending on context

Romanian present tense can cover both a simple present and, in the right context, an ongoing action.

If you wanted a past meaning, you would need a different form, for example:

• Am văzut avionul. = We saw / We have seen the plane.

The dictionary form is a vedea, which means to see.

Romanian verbs are normally listed with a:

• a vedea = to see
• a merge = to go
• a avea = to have

So when learning vocabulary, you would usually memorize a vedea, not vedem by itself.

Yes. If you want a plane instead of the plane, you would usually say:

• Vedem un avion. = We see a plane.

So compare:

• Vedem avionul. = We see the plane.
• Vedem un avion. = We see a plane.

That contrast is very important in Romanian, just as in English.

No. Avionul itself is the direct object, so nothing else is needed.

• Vedem avionul. = We see the plane.

If you wanted to replace avionul with a pronoun, you would use a clitic pronoun:

• Îl vedem. = We see it / We see him

Here îl stands for a masculine or neuter singular direct object. Since avion is neuter and behaves like masculine in the singular, îl is the correct pronoun.
