Sem experiência, a candidata precisa de mais prática.

Because experiência is being used in a general, uncountable sense here: without experience.

After sem, Portuguese often uses a noun with no article when the meaning is broad or generic:

• sem experiência = without experience
• sem dinheiro = without money
• sem paciência = without patience

You would add an article if you meant a specific kind of experience:

• sem a experiência necessária = without the necessary experience

Sem experiência is an introductory phrase placed at the beginning of the sentence. The comma separates that opening phrase from the main clause:

• Sem experiência, a candidata precisa de mais prática.

This is very natural in Portuguese, especially in careful writing. It helps the reader hear the pause and understand the structure.

Without the comma, the sentence would still be understandable in many contexts, but the comma is the more polished choice here.

In Portuguese, singular countable nouns usually need some kind of determiner, such as an article:

• a candidata = the candidate
• uma candidata = a candidate

Saying just candidata in a normal sentence would usually sound incomplete. Portuguese uses articles more often than English does.

Because candidata is the feminine form of the noun. Portuguese nouns referring to people often change form depending on gender:

• o candidato = the male candidate
• a candidata = the female candidate

Here, the sentence is specifically talking about a woman, so a candidata is correct.

Because precisar, when it means to need, normally takes de before a noun:

• precisar de ajuda = to need help
• precisar de tempo = to need time
• precisar de mais prática = to need more practice

So in this sentence, de is required because mais prática is a noun phrase.

A useful contrast:

• Ela precisa de prática. = She needs practice.
• Ela precisa praticar. = She needs to practice.

With another verb in the infinitive, Brazilian Portuguese usually does not use de.

Here, mais means more, and prática is a noun meaning practice.

So:

• mais prática = more practice

This is similar to English, where practice can be an uncountable noun.

It is a noun here.

That matters because prática can also be the feminine form of the adjective prático, meaning practical. But in this sentence, the structure tells you it is a noun:

• precisa de mais prática = needs more practice

If it were an adjective, it would normally describe another noun:

• uma solução prática = a practical solution

So here, prática means practice, not practical.

They are related, but not identical.

• experiência = experience, especially accumulated real-world exposure
• prática = practice, repetition, training, hands-on doing

So the sentence suggests this idea:

Because the candidate lacks experience, she needs more practice.

In other words, prática is something that can help build experiência.

Yes. Portuguese allows some flexibility.

For example:

• A candidata precisa de mais prática.
• Sem experiência, a candidata precisa de mais prática.
• A candidata, sem experiência, precisa de mais prática.

Putting Sem experiência first gives it more emphasis. It sets the situation before giving the main information.

They mean different things.

• mais prática = more practice
• muita prática = a lot of practice

Mais is comparative. It implies comparison with the current amount:

• she has some practice, but she needs more

Muita just describes a large quantity, without directly comparing it to what she already has.

Not exactly. Precisa means needs.

• precisa de mais prática = needs more practice

This expresses necessity, but not the same kind of strong obligation as must in English.

For stronger obligation, Portuguese might use expressions like:

• tem que = has to
• deve = should / must, depending on context

Here, precisa sounds natural and appropriate because the idea is about what is necessary for improvement.

They mainly show where the stress goes.

• experiência → stress on ên
• prática → stress on prá

So you say roughly:

• ex-pe-ri-ÊN-ci-a
• PRÁ-ti-ca

The accent also helps distinguish correct vowel quality and pronunciation. In Portuguese, accent marks are an important part of spelling, not optional decorations.

It can mean either, depending on context.

In Brazilian Portuguese, candidato/candidata may refer to:

• a political candidate
• a job applicant
• someone being considered for a position or role

In this sentence, it most naturally sounds like a job or selection context, especially because of the mention of experience and practice.
