Bệnh nhân nói về triệu chứng và dị ứng.

Here is the word-by-word breakdown:

• bệnh nhân = patient
• nói = speak, talk, say
• về = about
• triệu chứng = symptom / symptoms
• và = and
• dị ứng = allergy / allergies

So the structure is very close to English: patient + talk + about + symptoms + and + allergies.

Mostly yes. Vietnamese often uses a straightforward Subject + Verb + Object/Complement order here:

• Bệnh nhân = subject
• nói về = verb phrase, talk about
• triệu chứng và dị ứng = what the patient is talking about

So it maps neatly to English: The patient talks about symptoms and allergies.

Về means about in this sentence.

• nói = to speak / to talk
• nói về = to talk about

If you want to say someone talks about a topic, về is the normal word to use.

Examples:

• Tôi nói về gia đình tôi. = I talk about my family.
• Bác sĩ nói về thuốc. = The doctor talks about medicine.

So in your sentence, nói về triệu chứng và dị ứng means talk about symptoms and allergies.

Usually, no, not if you mean talk about symptoms and allergies.

Nói by itself often means say or speak, but when introducing a topic, Vietnamese usually uses nói về.

So:

• nói về triệu chứng và dị ứng = talk about symptoms and allergies

Without về, the sentence sounds incomplete or unnatural for this meaning.

Vietnamese does not use articles like a, an, and the in the same way English does.

So bệnh nhân can mean:

• a patient
• the patient
• patients in some contexts

The exact meaning depends on context.

In a medical dialogue or textbook sentence, bệnh nhân is often understood as the patient or a patient, depending on what has already been mentioned.

Vietnamese nouns are often not marked for singular or plural unless the speaker wants to make that explicit.

So:

• triệu chứng can mean symptom or symptoms
• dị ứng can mean allergy or allergies

Context tells you which one is intended.

If you want to make plurality clearer, Vietnamese can add words like:

• những triệu chứng = symptoms
• các triệu chứng = the symptoms / various symptoms

But in many natural sentences, Vietnamese leaves this unstated.

They are related medical ideas, but not the same thing.

• triệu chứng = symptoms, such as fever, pain, coughing, dizziness
• dị ứng = allergy or allergic reaction, such as a peanut allergy or a reaction to medicine

So the sentence means the patient is discussing both:

1. what they are experiencing physically, and
2. any allergies they have

Yes, bệnh nhân is a standard and somewhat formal medical term meaning patient.

It is very common in hospitals, clinics, medical forms, and doctor-patient conversations.

Examples:

• Bệnh nhân cần nghỉ ngơi. = The patient needs rest.
• Bệnh nhân có sốt. = The patient has a fever.

In everyday family conversation, people might sometimes say more specific things like người bệnh or just refer to the person directly, but bệnh nhân is the normal professional term.

A rough pronunciation guide for English speakers is:

• Bệnh ≈ baynh
• nhân ≈ nyuhn
• nói ≈ noy
• về ≈ veh
• triệu ≈ chee-oo or tree-oo depending on accent
• chứng ≈ choong with a stopped ending
• và ≈ vah
• dị ứng ≈ zee oong in the north, often closer to yee oong in the south

A few important notes:

• Vietnamese is tonal, so the pitch pattern matters.
• nh is a common Vietnamese sound, somewhat like ny in canyon.
• tr and ch may sound close for learners, though many speakers distinguish them.

If you want to sound natural, it is best to learn the sentence with audio rather than relying only on English spelling.

Vietnamese verbs do not change form the way English verbs do.

So nói can mean:

• talk
• talks
• talked
• speaking

The time reference usually comes from context or time words.

For example:

• Bệnh nhân nói về triệu chứng và dị ứng. = The patient talks about / is talking about symptoms and allergies.
• Hôm qua, bệnh nhân nói về triệu chứng và dị ứng. = Yesterday, the patient talked about symptoms and allergies.

So the verb stays nói.

Yes. Vietnamese often does not explicitly mark tense, so this sentence can be understood in different ways depending on context:

• The patient talks about symptoms and allergies
• The patient is talking about symptoms and allergies

If the context is happening right now, English may naturally translate it as is talking about. If it is a general description, talks about also works.

Và is the standard word for and in formal and neutral Vietnamese.

So:

• triệu chứng và dị ứng = symptoms and allergies

In casual speech, Vietnamese sometimes links ideas without always needing an explicit and, but và is completely correct and natural here, especially in a medical or textbook sentence.

Yes, depending on the nuance.

Some possibilities are:

• trình bày về = present/explain about, more formal
• mô tả = describe
• đề cập đến = mention
• chia sẻ về = share about

But nói về is the most direct and basic way to say talk about.

For example:

• Bệnh nhân mô tả triệu chứng và dị ứng. = The patient describes symptoms and allergies.
• Bệnh nhân đề cập đến dị ứng. = The patient mentions allergies.

So nói về is a good beginner-friendly choice.
