Họ tìm bom.

Họ here means they.

A few useful notes:

• It is a third-person plural pronoun.
• In this sentence, họ is the subject: They ...
• Be careful: họ can also mean family name / surname in other contexts, but not here.

So in Họ tìm bom, họ is clearly the pronoun they.

Yes. This sentence uses the basic Vietnamese word order:

Subject + Verb + Object

So:

• Họ = subject
• tìm = verb
• bom = object

That makes the structure very straightforward for an English speaker:

• Họ tìm bom
• They search for bombs

This is a very common question, and it is important.

Tìm usually means look for, search for, or seek — not the successful result find.

So:

• tìm bom = look for bombs / search for bombs

If you want to say find in the sense of successfully locating something, Vietnamese often uses:

• tìm thấy = find, manage to find

For example:

• Họ tìm bom. = They are looking for bombs.
• Họ tìm thấy bom. = They found bombs.

So even if the translation you were shown says find, learners should know that tìm by itself usually focuses on the search, not the result.

Vietnamese does not use articles the same way English does.

In English, you often need words like:

• a bomb
• the bomb
• some bombs

In Vietnamese, a bare noun like bom can often stand by itself, and the exact meaning depends on context.

So bom could be understood as:

• a bomb
• bombs
• the bomb
• bombs in general

depending on the situation.

If you want to be more specific, Vietnamese can add other words, for example:

• một quả bom = one bomb / a bomb
• những quả bom = bombs
• các quả bom = the bombs / bombs (depending on context)

But in a short sentence, bom alone is completely natural.

By itself, bom does not clearly mark singular or plural.

That means Họ tìm bom could mean:

• They are looking for a bomb
• They are looking for bombs

Context tells you which meaning is intended.

If you need to make number clearer, you can say:

• Họ tìm một quả bom. = They are looking for one bomb.
• Họ tìm những quả bom. = They are looking for bombs.

This is very common in Vietnamese: nouns are often left unmarked for number unless the speaker wants to be specific.

Not necessarily.

Vietnamese often uses classifiers when a noun is counted or specifically identified, but classifiers are not required in every sentence.

For bomb, the common classifier is:

• quả

Examples:

• một quả bom = one bomb
• hai quả bom = two bombs

But in Họ tìm bom, the noun is being used in a general way, so leaving out the classifier is normal.

So both of these are possible, but they are slightly different in feel:

• Họ tìm bom. = general, natural, less specific
• Họ tìm quả bom. = more specific, like the bomb or a particular bomb, depending on context

By itself, this sentence does not explicitly mark tense.

Vietnamese often relies on context instead of changing the verb form.

So Họ tìm bom could mean:

• They look for bombs
• They are looking for bombs
• They looked for bombs
• They will look for bombs

depending on the situation.

If you want to make the time clearer, you can add time/aspect words:

• Họ đang tìm bom. = They are looking for bombs.
• Họ đã tìm bom. = They looked for / searched for bombs.
• Họ sẽ tìm bom. = They will look for bombs.

So the verb tìm itself does not change form.

A simple pronunciation guide:

• Họ — roughly like haw with a short, heavy drop in tone
• tìm — roughly like teem with a falling tone
• bom — roughly like English bom in bomb, but without the final b sound

Tone-wise:

• họ has the nặng tone
• tìm has the huyền tone
• bom has the level tone

Important: English approximations are only rough. The tones matter a lot in Vietnamese, so it is best to hear native audio if possible.

Yes.

If you want to emphasize that the action is happening right now, you can say:

• Họ đang tìm bom.

This means:

• They are looking for bombs.
• They are searching for bombs right now.

Without đang, the sentence is more neutral and depends more on context.

So:

• Họ tìm bom. = general statement / context-dependent
• Họ đang tìm bom. = action in progress

Yes, it is complete and grammatical.

It is a short, simple sentence with:

• a subject: họ
• a verb: tìm
• an object: bom

Vietnamese often allows very compact sentences like this, especially when the context already makes the situation clear.

So Họ tìm bom. is perfectly natural as a basic sentence.
