Banda adezivă închide cutia.

Because banda is the definite form: the tape.

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

• bandă = a tape / tape
• banda = the tape

So Banda adezivă means the adhesive tape.

For the same reason: cutia is the definite form, meaning the box.

• cutie = a box
• cutia = the box

Romanian often adds the definite article to the noun itself.

Also notice that cutie changes a bit when it becomes definite:

• cutie → cutia

This kind of change is normal in Romanian noun forms.

In Romanian, adjectives often come after the noun.

So:

• bandă adezivă = adhesive tape
• literally: tape adhesive

This is a very common word order in Romanian. English usually puts adjectives before the noun, but Romanian usually places them after it.

Because the adjective has to agree with the noun in gender, number, and definiteness-related form.

Here, bandă is a feminine singular noun, so the adjective also takes a feminine singular form:

• masculine singular: adeziv
• feminine singular: adezivă

So:

• un material adeziv = an adhesive material
• o bandă adezivă = an adhesive tape

Închide means closes or shuts.

In this sentence, with tape as the subject, English might more naturally say seals the box rather than closes the box. But Romanian can still use închide here to express the idea that the tape closes it up.

So depending on context, închide can be understood as:

• closes
• shuts
• sometimes, in practical context, seals up

Închide is the 3rd person singular present tense form of the verb a închide = to close.

The subject is Banda adezivă = the adhesive tape, which is singular, so the verb must also be singular.

Present tense of a închide:

• eu închid = I close
• tu închizi = you close
• el/ea închide = he/she/it closes
• noi închidem = we close
• voi închideți = you all close
• ei/ele închid = they close

So Banda adezivă închide cutia uses the correct he/she/it form: închide.

Yes, Romanian word order is more flexible than English, although the most neutral order here is:

• Banda adezivă închide cutia.

You may also see different orders for emphasis, for example:

• Cutia o închide banda adezivă.
• Banda adezivă cutia o închide.

But these sound more marked or emphatic. For a learner, the basic subject + verb + object order is the safest and most natural choice.

The letter ă is a very common Romanian vowel. It is a short, neutral sound, somewhat like the a in English sofa.

So adezivă is pronounced roughly like:

• ah-deh-ZEE-vuh

with the final ă sounding like a soft uh.

This sound appears in many Romanian words, so it is worth getting used to early.

In închide, the ch is pronounced like a hard k sound.

So închide sounds roughly like:

• een-KEE-deh

The reason is that in Romanian, ch before i or e is used to keep the hard k sound.

Compare:

• ce = like che in English check? No — Romanian ce is more like che/tʃe
• che = hard ke
• chi = hard ki

So in închide, the spelling ensures you say k, not a softer sound.

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

That is why you get:

• banda = the tape
• cutia = the box

instead of separate words for the.

This is one of the big structural differences between English and Romanian, and it appears constantly in everyday sentences.

It is grammatically correct, but depending on context, a Romanian speaker might also choose a more specific verb such as sigilează if the idea is seals rather than simply closes.

For example:

• Banda adezivă sigilează cutia. = The adhesive tape seals the box.

But Banda adezivă închide cutia is still understandable and useful for learning grammar and sentence structure.
