Regula permite o valiză.

The basic dictionary form is regulă. In this sentence, it is definite singular, meaning the rule, so Romanian adds the definite article to the end of the noun.

For many feminine nouns ending in -ă, the definite form changes that ending to -a:

• regulă = a rule
• regula = the rule

So Regula here means the rule.

Romanian usually puts the definite article onto the noun itself instead of using a separate word like English the.

So:

• regulă = a rule
• regula = the rule

This is one of the big differences between English and Romanian.

Here, o is the feminine singular form of the indefinite article, so it means a.

• o valiză = a suitcase

It is used because valiză is a feminine singular noun.

Yes. O can function both as:

• the indefinite article a
• the number one in the feminine singular

So o valiză can mean either a suitcase or one suitcase. Context tells you which meaning is intended. In a sentence about a rule or allowance, English often translates it as one suitcase if the idea is a limit.

Because nouns in Romanian have grammatical gender, and valiză belongs to the feminine gender.

That affects words around it:

• o valiză = a suitcase
• două valize = two suitcases

You often have to learn the gender along with the noun, just as you learn irregular plural forms in English.

Permite is the 3rd person singular present tense form of a permite.

It matches the subject Regula:

• eu permit = I allow
• tu permiți = you allow
• el/ea permite = he/she/it allows

Since regula is it grammatically, permite is the correct form.

Because a permite normally takes a direct object. In this sentence, o valiză is that object, so no preposition is needed.

Romanian works like English here:

• The rule allows a suitcase
• Regula permite o valiză

Also, there is no pe here because o valiză is an inanimate, indefinite direct object.

Yes. Subject + verb + object is the most neutral and common order here:

• Regula = subject
• permite = verb
• o valiză = object

So Regula permite o valiză is the straightforward, standard way to say it.

A simple approximation is:

reh-GOO-lah per-MEE-teh o vah-LEE-zuh

A few helpful notes:

• g in Regula is a hard g, like in go
• e is pronounced clearly, not reduced like in English
• ă in valiză is a short central vowel, similar to the a in English sofa

The main stresses are:

• ReGUla
• perMIte
• vaLIză
