Se verifică nu numai anvelopa, ci și janta.

Se verifică is a very common Romanian construction that often corresponds to English is checked / gets checked / one checks.

Here, se does not mean himself/herself/itself in a literal reflexive sense. Instead, it helps create an impersonal or passive-like meaning.

So:

• Se verifică anvelopa = The tire is checked
• or more literally, One checks the tire

In practical terms, Romanian often prefers this se + verb structure where English might use a passive.

In this sentence, se is used to avoid naming the person doing the action.

That is very natural in Romanian when the focus is on what gets done, not who does it.

Compare:

• Mecanicul verifică anvelopa. = The mechanic checks the tire.
• Se verifică anvelopa. = The tire is checked.

So se helps make the sentence sound more general, procedural, or instructional.

It is singular because the things being checked are mentioned as singular nouns:

• anvelopa = the tire
• janta = the rim

In this pattern, the verb matches the grammatical number of the thing being checked.

So:

• Se verifică anvelopa. = singular
• Se verifică anvelopele. = plural

If both nouns were turned into a plural idea, you would normally get plural agreement, for example:

• Se verifică nu numai anvelopele, ci și jantele.

Because they are feminine singular definite nouns.

In Romanian, the definite article is usually attached to the end of the noun instead of being a separate word like English the.

So:

• anvelopă = tire, a tire
• anvelopa = the tire
• jantă = rim
• janta = the rim

This final -a is the definite article for many feminine singular nouns.

The dictionary form is the indefinite singular: anvelopă.

When you add the definite article, the form becomes anvelopa.

This is a very common pattern:

• casă → casa
• roată → roata
• jantă → janta
• anvelopă → anvelopa

Notice that ă often becomes a in the definite singular feminine form.

This is the Romanian pattern for not only ... but also ...

So:

• nu numai anvelopa, ci și janta

means:

• not only the tire, but also the rim

It is a fixed correlative structure, and it is very common in both formal and everyday Romanian.

Other similar variants you may also see are:

• nu doar ..., ci și ...
• nu numai ..., dar și ...

But nu numai ..., ci și ... is a very standard and elegant version.

Yes, Romanian word order is fairly flexible, though some versions sound more natural than others depending on context.

The given sentence:

• Se verifică nu numai anvelopa, ci și janta.

is perfectly natural.

You could also say:

• Nu numai anvelopa se verifică, ci și janta.

But that version gives a slightly different emphasis and may sound more contrastive or stylistically marked.

In neutral instructional language, the original order is very natural.

Because in Romanian, ci și together express the but also part of the structure.

So you should think of it as a unit:

• nu numai ... ci și ... = not only ... but also ...

Here:

• ci roughly corresponds to but
• și corresponds to also

You normally use them together in this pattern.

Very often, yes.

Ci is typically used to correct or contrast after a negative idea.

For example:

• Nu cafea, ci ceai. = Not coffee, but tea.
• Nu numai anvelopa, ci și janta. = Not only the tire, but also the rim.

So ci is strongly associated with structures involving nu.

Yes. A more explicitly passive version would be:

• Sunt verificate nu numai anvelopa, ci și janta.

However, in ordinary Romanian, the se construction is often more natural and more common in general statements, instructions, manuals, and descriptions of procedures.

So while the passive with a fi is possible, se verifică is often the preferred choice.

These are two different parts of the wheel assembly:

• anvelopa = the tire/tyre
• janta = the rim

That is why the sentence contrasts them: it is saying that not only the tire is checked, but the rim too.

This is useful vocabulary because English learners sometimes confuse:

• roată = wheel
• anvelopă = tire/tyre
• jantă = rim

Romanian often uses the singular when speaking about a typical object in a procedure, especially in technical or instructional contexts.

So the singular here can mean something like:

• check the tire and the rim
• or, in a general inspection process, each tire and rim are checked

This is similar to how English sometimes uses singular in instructions, for example Check the tire even when the instruction is general.

If the speaker wanted to refer clearly to multiple tires and rims, they could use the plural:

• Se verifică nu numai anvelopele, ci și jantele.

The correct form is și, with the comma-below diacritic on ș.

• și = and / also

Writing si without the diacritic is common in informal typing, but it is not the correct standard spelling.

The pronunciation also changes:

• și sounds like sh
  • a short i

So in careful Romanian writing, you should use și, not si.

A rough pronunciation guide is:

Se verifică nu numai anvelopa, ci și janta.
seh veh-ree-FEE-kuh noo noh-MAI ahn-veh-LOH-pah, chee sh ee ZHAN-tah

A few useful pronunciation notes:

• ce/ci are usually pronounced like che/ch in this context, so ci sounds roughly like chee
• ș sounds like English sh
• j in janta sounds like the s in measure
• ă is a short central vowel, somewhat like a weak uh

No, not in this sentence.

Even though se can sometimes be reflexive in other contexts, here that would be misleading.

This is not saying:

• the tire checks itself

Instead, it is the Romanian impersonal/passive-like structure meaning:

• the tire is checked
• one checks the tire

So for this sentence, do not interpret se literally as itself.
