Mintea este puternică.

Because mintea is the definite form of the noun minte.

• minte = mind / a mind
• mintea = the mind

Romanian usually attaches the definite article to the end of the noun instead of putting a separate word like the in front.

So:

• minte → mind
• mintea → the mind

In this sentence, mintea is the natural form.

Because Romanian often uses the definite form for general ideas, especially with abstract nouns.

So Mintea este puternică can mean something like:

• The mind is powerful
• Mind is powerful (in a general sense)

This is normal Romanian usage and does not always mean one specific individual mind. English and Romanian handle general statements differently.

Este means is.

It is the 3rd person singular form of the verb a fi = to be.

So:

• mintea = the mind
• este = is
• puternică = powerful

A very common shorter spoken form is e:

• Mintea e puternică.

That is more casual, but it means the same thing.

Because adjectives in Romanian usually agree with the noun in gender and number.

Here, mintea is:

• feminine
• singular

So the adjective must also be feminine singular:

• masculine singular: puternic
• feminine singular: puternică
• masculine plural: puternici
• feminine plural: puternice

Since mintea is feminine singular, puternică is the correct form.

You mainly learn the gender as part of the noun, just as you do in many other European languages.

In dictionaries, minte is a feminine noun. That is why it takes:

• the feminine definite form mintea
• the feminine adjective puternică

There is not always a perfect rule from the spelling alone, so it is best to memorize the noun together with its article or an adjective form.

A simple English-friendly approximation is:

MEEN-tya YES-teh poo-TER-nee-kuh

A few pronunciation notes:

• mintea: the ea is pronounced together, roughly like tya
• este often sounds like YES-te
• puternică has stress on ter: poo-TER-nee-kuh
• ă is a short neutral vowel, similar to the a in sofa

Romanian spelling is fairly consistent, so once you learn the sounds, pronunciation gets easier.

ă is a very common Romanian vowel. It sounds like the unstressed vowel in English sofa or about.

So the last part of puternică is approximately:

-kuh

This is different from plain a, which is a clearer open vowel.

Yes, but the basic neutral order here is:

Mintea este puternică.

This is the most straightforward way to say it.

You may also see more marked or literary orders, such as:

Puternică este mintea.

That sounds more emphatic or poetic, not the normal default order for everyday speech.

Normally, no. Romanian usually keeps the verb to be in sentences like this.

So the normal forms are:

• Mintea este puternică.
• Mintea e puternică. (more common in speech)

Leaving it out completely would not sound natural in standard Romanian.

Usually mind.

Minte refers to things like:

• thought
• intellect
• reason
• mental capacity
• cleverness

If you mean the physical brain, Romanian normally uses creier.

So:

• minte = mind
• creier = brain

No. Puternic / puternică can mean strong or powerful in both physical and abstract senses.

So in this sentence, puternică means something like:

• powerful
• strong

Because mind is abstract, English usually prefers powerful, but strong can also work depending on context.
