Noi descifrăm cifrul.

Yes. In Romanian, the verb ending often already shows the subject, so descifrăm by itself can mean we decipher.

Adding noi is optional and usually gives one of these effects:

• emphasis: We are deciphering it.
• contrast: We decipher the cipher, not someone else.
• clarity, especially for learners or in certain contexts

So both are possible:

• Noi descifrăm cifrul.
• Descifrăm cifrul.

The second one is often more natural in everyday Romanian unless you want to stress noi.

Descifrăm is the 1st person plural present tense form of the verb a descifra, meaning to decipher.

So the pattern is:

• eu descifrez = I decipher
• tu descifrezi = you decipher
• el/ea descifrează = he/she deciphers
• noi descifrăm = we decipher
• voi descifrați = you all decipher
• ei/ele descifrează = they decipher

In this sentence, descifrăm matches noi = we.

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

So:

• cifru = a cipher / a code
• cifrul = the cipher / the code

Unlike English, Romanian usually puts the at the end of the noun instead of before it.

A few similar examples:

• băiat = boy

• băiatul = the boy

• copil = child
• copilul = the child

So cifrul literally means cipher-the, but in natural English that is simply the cipher.

It is the direct object.

The sentence breaks down like this:

• Noi = we → subject
• descifrăm = decipher → verb
• cifrul = the cipher → direct object

So the structure is:

We + decipher + the cipher

Romanian often uses the same basic word order as English in simple sentences: subject + verb + object.

Yes, absolutely. That is very natural Romanian.

Because the verb form descifrăm already tells you the subject is we, the pronoun is often left out.

So:

• Descifrăm cifrul. = We decipher the cipher.
• Noi descifrăm cifrul. = We decipher the cipher. / We are the ones deciphering the cipher.

The version with noi sounds a bit more emphatic.

Yes. Romanian word order is fairly flexible, although Noi descifrăm cifrul is the most neutral version.

You may also see:

• Descifrăm cifrul. → neutral, very common
• Cifrul îl descifrăm noi. → more marked, emphasizing the cipher and/or we
• Noi cifrul îl descifrăm. → strongly contrastive or stylistically marked

For a beginner, the safest pattern is:

(subject) + verb + object

So Noi descifrăm cifrul is a good standard model.

A helpful approximation is:

des-ci-FRUM

More accurately:

• de as in desk without the final sk
• sci here sounds like chi in English cheese, so ci gives a ch sound
• frăm has stress on this syllable
• ă is a short central vowel, something like the a in sofa

So descifrăm is approximately:

des-chi-FRUM
IPA: /des.tʃiˈfrəm/

The stress is on the last syllable: -frăm.

A good approximation is:

CHEE-frool

More accurately:

• ci = chee with a ch sound at the start, like cheese
• frul = frool, but shorter and smoother

IPA: /ˈtʃifrul/

The stress is on the first syllable: CI-.

In Romanian, the letter c changes sound depending on the vowel after it.

Before e or i, c is usually pronounced like English ch.

So:

• ci → chi / ch
• ce → che / ch

That is why:

• cifru begins with a ch sound
• descifrăm also contains that same sound

This is a very common spelling rule in Romanian.

It can often mean both, depending on context.

Romanian does not usually separate simple present and present progressive the way English does.

So descifrăm can mean:

• we decipher
• we are deciphering

The surrounding context tells you which is more natural.

For example:

• În fiecare zi descifrăm mesaje. = We decipher messages every day.
• Acum descifrăm cifrul. = We are deciphering the cipher now.

Cifru usually means cipher, but in some contexts it can also be understood as code.

Depending on the situation, it may refer to:

• a cryptographic cipher
• a coded system
• sometimes a numerical code or encoded message

So the English translation may vary slightly by context, even though the Romanian word is the same.

Yes: cifru is a neuter noun in Romanian.

Romanian neuter nouns behave like:

• masculine in the singular
• feminine in the plural

So in the singular you get:

• un cifru = a cipher
• cifrul = the cipher

And in the plural:

• două cifruri = two ciphers
• cifrurile = the ciphers

For this sentence, the important thing is simply that cifrul is the singular definite form.

No. Romanian usually does not use a separate word like English the before the noun.

Instead, the definite article is attached to the noun itself:

• cifru = a cipher
• cifrul = the cipher

So you should think of -ul as doing the job of English the.

That is one of the most noticeable differences between Romanian and English grammar.
