Tôi chọn loại cây này.

Vietnamese word order here is:

subject + verb + object

So:

• Tôi = subject
• chọn = verb
• loại cây này = object

The word này means this, but unlike English, demonstratives in Vietnamese usually come after the noun phrase they modify.

So English this type of tree/plant becomes Vietnamese loại cây này.

Tôi is a common, neutral way to say I in Vietnamese.

However, Vietnamese pronouns depend a lot on age, relationship, and social situation. So tôi is not the only way to say I.

For example, depending on context, a speaker might say:

• mình
• em
• anh
• chị
• con
• cháu

But for learners, tôi is a very safe and standard form to learn first.

Yes. Chọn means to choose, to pick, or to select.

In Vietnamese, verbs do not change form the way English verbs do. So chọn stays the same regardless of the subject.

Examples:

• Tôi chọn = I choose / I am choosing / I chose
• Anh ấy chọn = he chooses / he chose
• Họ chọn = they choose / they chose

The exact time is usually understood from context or shown with time words.

Vietnamese verbs usually do not change for tense.

So chọn can mean:

• choose
• am choosing
• chose
• will choose

depending on context.

If needed, Vietnamese can add time markers such as:

• đã = past
• đang = ongoing
• sẽ = future

For example:

• Tôi đã chọn loại cây này. = I chose this type of plant/tree.
• Tôi đang chọn loại cây này. = I am choosing this type of plant/tree.
• Tôi sẽ chọn loại cây này. = I will choose this type of plant/tree.

Loại means type, kind, or category.

So loại cây này is literally something like:

• this type of tree
• this kind of plant

This is important because loại makes the phrase more about a kind/species/category, not just one individual object.

So the sentence may suggest choosing a type of plant/tree rather than selecting one specific tree in front of you.

Cây can mean tree, but it can also mean plant, depending on context.

So loại cây này could be understood as:

• this type of tree
• this kind of plant

If the broader context is gardening or houseplants, plant may sound more natural in English. If the context is about actual trees, then tree is better.

Vietnamese often relies on context more than English does.

In English, we say:

• this tree
• this type of plant

In Vietnamese, này usually comes after the noun or noun phrase:

• cây này = this tree/plant
• loại cây này = this type of tree/plant

This is a very common Vietnamese pattern.

Other examples:

• người này = this person
• cuốn sách này = this book
• cái bàn này = this table

So này after the noun is completely normal.

Yes, and the meaning changes slightly.

• Tôi chọn cây này = I choose this tree/plant.
• Tôi chọn loại cây này = I choose this type/kind of tree/plant.

So:

• cây này points to a specific tree or plant
• loại cây này points to a category, kind, or variety

If you are choosing one individual plant in front of you, cây này is often more natural. If you are choosing among species or types, loại cây này is more natural.

Not exactly in the usual sense.

Vietnamese has classifiers like:

• cái
• con
• chiếc
• quyển/cuốn

But loại here is better understood as a noun meaning type or kind.

So loại cây này is structurally similar to:

• this kind of plant
• this type of tree

It is not just a grammatical classifier with little meaning; it carries real meaning by specifying category/type.

A rough pronunciation guide for English speakers is:

• Tôi ≈ toy
• chọn ≈ somewhat like chon with a heavy falling tone and a short vowel
• loại ≈ roughly lo-eye, with a broken/dipping tone on the first part
• cây ≈ roughly cay like kay with a different vowel quality
• này ≈ roughly nye / nai depending on accent, with a rising tone

A few important notes:

• Vietnamese is a tonal language, so tone matters a lot.
• The exact pronunciation varies between northern and southern accents.
• It is better to learn the whole sentence from audio than to rely only on English-style approximations.

Yes, it is grammatical and natural, but the best version depends on the situation.

• If you mean I choose this specific plant/tree, then Tôi chọn cây này may sound more natural.
• If you mean I choose this type/variety of plant/tree, then Tôi chọn loại cây này is very appropriate.

So the sentence is correct; it just has a slightly more specific meaning because of loại.

Sometimes, yes.

Vietnamese often drops subjects when they are already understood from context.

So in a conversation, someone might simply say:

• Chọn loại cây này.

depending on the situation.

However, for a full clear sentence, especially in learning materials, keeping tôi is very normal and helpful.

The verb phrase can stay the same, but the pronoun may change.

Formal/neutral:

• Tôi chọn loại cây này.

More casual, depending on who is speaking:

• Mình chọn loại cây này.
• Em chọn loại cây này.
• Anh chọn loại cây này.

The correct choice depends on the speaker’s age, gender, and relationship to the listener.

So the sentence pattern stays the same, but the pronoun can change a lot in real life.
