Lan sợ con chó.

The word order is:

subject + verb + object

So here:

• Lan = the subject
• sợ = the verb
• con chó = the object

Vietnamese often follows the same basic order as English in simple sentences, so this is very straightforward: Lan → is afraid of → the dog / a dog

Lan is a proper name, not a pronoun. It is a very common Vietnamese given name, usually for women.

Because it is a name, it is capitalized:

• Lan

So the sentence is talking about a specific person named Lan, not about she or her in general.

Sợ means to be afraid of, to fear, or to be scared of.

In this sentence, it describes Lan’s feeling toward the dog.

A useful point for English speakers: Vietnamese does not need a separate word like of here. English says:

• afraid of the dog

Vietnamese says:

• sợ con chó

So sợ already works with its object directly.

Con is a classifier, also sometimes called a measure word or noun classifier.

Vietnamese often uses classifiers before nouns, especially when talking about individual countable things. Con is the classifier commonly used for animals.

So:

• chó = dog
• con chó = a dog / the dog

This is very natural Vietnamese. Since a dog is an animal, con is the expected classifier here.

Yes, you can, but the nuance changes a little.

• Lan sợ con chó often refers to a specific dog or treats the dog as a single identifiable animal.
• Lan sợ chó can sound more general, like Lan is afraid of dogs or Lan is afraid of dog(s) as a kind/category, depending on context.

So con helps make the noun phrase feel more like an individual dog.

It can mean either the dog or a dog, depending on context.

Vietnamese does not have articles exactly like English a/an/the. So con chó by itself does not always tell you whether the dog is definite or indefinite.

Context decides:

• if the dog is already known in the conversation, it may mean the dog
• if it is just being introduced, it may mean a dog

So in isolation, Lan sợ con chó could be understood as either:

• Lan is afraid of the dog
• Lan is afraid of a dog

No tense is explicitly marked here.

Vietnamese often does not mark tense the way English does. A sentence like Lan sợ con chó can mean different time frames depending on context:

• Lan is afraid of the dog
• Lan was afraid of the dog
• Lan fears the dog

If you want to make the time clearer, Vietnamese can add time words or markers, such as:

• đã for past
• đang for ongoing action/state in some contexts
• sẽ for future

But in this sentence, there is no explicit tense marker.

The accent mark is very important because Vietnamese is a tonal language.

Sợ has:

• the vowel ơ
• a tone mark on it

That means you cannot ignore the spelling details. In Vietnamese, changing the tone or vowel can create a different word.

For a learner, the key takeaway is:

• learn sợ as a full unit: consonant + vowel + tone
• do not treat accent marks as optional

If you are studying a specific accent, your teacher or audio source will help you produce the tone more accurately.

Most naturally, Lan sợ con chó suggests fear of one particular dog or a specific dog in the situation.

That is because:

• con marks an individual animal
• the whole phrase con chó sounds like a concrete noun phrase

If you wanted to express a more general fear of dogs as a type, Lan sợ chó would often be more natural.

So the version with con tends to feel more specific.

Yes. Depending on context, good English translations include:

• Lan is afraid of the dog
• Lan is scared of the dog
• Lan fears the dog

For most everyday situations, afraid of or scared of is the most natural English translation.

It is spoken as three parts:

• Lan
• sợ
• con chó

A learner should pay special attention to:

• the tone on sợ
• the classifier phrase con chó being said smoothly together

Vietnamese is syllable-based, so each syllable is clearly pronounced:

• Lan
• sợ
• con
• chó

But con chó forms one noun phrase, so it belongs together in meaning: dog / the dog / a dog.
