Frigiderul este lângă ușă, iar ușa lui este închisă.

Because Romanian usually puts the definite article at the end of the noun.

• frigider = fridge / a fridge
• frigiderul = the fridge

So frigiderul means the fridge.

Romanian often uses a bare noun after a preposition of place in cases where English would naturally say the. So lângă ușă is a very normal way to say by the door / next to the door.

Later, ușa is definite because now the speaker is referring to that door as a specific thing: the door. So:

• ușă = door / a door
• ușa = the door

Lângă means near, next to, or beside.

So este lângă ușă means that the fridge is positioned by the door.

Iar is a conjunction that often means and, but with a slight sense of contrast or shift to a related point. It is very common when moving from one clause to another that adds parallel information.

Here, iar connects:

• one fact about the fridge
• another fact about its door

You could think of it as and, or sometimes and meanwhile / whereas, depending on context. Și would also mean and, but iar sounds a bit more natural here because it separates the two related statements more clearly.

Yes, lui often means his, but with an inanimate noun it is translated as its in English.

So ușa lui literally means his/its door, and here it refers to the fridge, so in natural English it becomes its door.

Romanian uses lui for a masculine or neuter possessor in the singular. Since frigider is a neuter noun, lui is the correct form.

Because Romanian commonly places this kind of possessive form after the possessed noun.

So:

• ușa lui = his/its door
• cartea lui = his book

This word order is normal in Romanian.

Yes. Ușa frigiderului is also correct and is even more explicit.

• ușa lui = its door
• ușa frigiderului = the fridge’s door / the door of the fridge

The version with lui avoids repeating frigider. The version with frigiderului makes the possessor completely clear.

Because adjectives in Romanian agree with the noun they describe.

Here, ușa is feminine singular, so the adjective must also be feminine singular:

• masculine singular: închis
• feminine singular: închisă

So ușa este închisă means the door is closed.

In normal standard Romanian, each clause keeps its own verb here:

• Frigiderul este lângă ușă
• ușa lui este închisă

So repeating este is the natural choice. Leaving it out would sound elliptical or stylistically marked, not like neutral everyday Romanian.

Frigider is a neuter noun in Romanian.

Romanian neuter nouns behave:

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

That matters because it affects forms like the article and possessives. In the singular, you get masculine-looking forms such as:

• frigiderul
• lui

So even though English speakers may think of a fridge as just it, Romanian still assigns it a grammatical gender.

The main ones are:

• ș as in ușă = like English sh
• ă as in ușă, lângă, închisă = a short, unstressed central vowel, somewhat like the final sound in sofa
• â does not appear in this sentence, but î does in închisă; â/î represent the same Romanian vowel, which has no exact English equivalent

So roughly:

• ușă sounds like OO-shuh
• lângă roughly like LUNG-guh
• închisă roughly like in-KHEE-suh, though the first vowel is not exactly English i

Because iar is linking two full clauses, each with its own verb:

• Frigiderul este lângă ușă
• ușa lui este închisă

In Romanian, it is standard to separate those with a comma when using iar in this way.
