Pragul este lângă ușă.

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

• prag = a threshold
• pragul = the threshold

Unlike English, Romanian usually does not put a separate word before the noun for the. It attaches the article to the noun instead.

In simple location phrases after a preposition, Romanian often uses the bare noun very naturally:

• lângă ușă
• pe masă
• în casă

English may still translate these with the, depending on context. So lângă ușă can be a perfectly normal way to say by the door.

If you want to make the door more specifically identified, Romanian often adds more information, for example:

• lângă ușa din față = by the front door
• lângă ușa apartamentului = by the apartment door

So in this sentence, ușă is not strange; it is a normal locative expression.

Este is the 3rd person singular of a fi = to be. It means is here.

• Pragul este lângă ușă. = standard/full form
• Pragul e lângă ușă. = very common shorter form in speech

You normally do not omit it completely in a sentence like this.

Lângă is a preposition meaning:

• near
• next to
• beside
• by

In this sentence, it shows physical position. It usually suggests something fairly close, often right beside something.

A related expression is aproape de, which also means near, but lângă often feels a bit more directly adjacent.

• prag is neuter
• ușă is feminine

This matters because Romanian articles and some endings depend on gender.

For example:

• neuter singular often behaves like masculine in the singular, so prag becomes pragul
• feminine singular definite would be ușa

So the gender helps explain why the words look the way they do.

• pragul is in the nominative, because it is the subject of the sentence.
• ușă is in the accusative, because it comes after the preposition lângă.

A useful thing for learners: in many Romanian nouns, the nominative and accusative forms look the same, so you often recognize the case from the sentence structure rather than from a different ending.

These are the main pronunciation points:

• ă = a short neutral vowel, like the a in English sofa
• â = a central vowel with no exact English equivalent; learners often approximate it with a muted uh, but it is not exactly the same
• ș = sh as in shoe

A rough English-style approximation of the whole sentence is:

PRA-gool YES-te luhn-guh OO-shuh

That is only approximate, but it is a useful start.

The sentence uses the most neutral order:

Subject + verb + place expression

• Pragul = subject
• este = verb
• lângă ușă = location

Romanian word order is more flexible than English, so other orders are possible for emphasis, for example:

• Lângă ușă este pragul.

But the original sentence is the plain, standard way to say it.
