Ghép bảng chữ cái với dãy số rồi thoát ra.

Yes. This is an imperative sentence: it is giving an instruction.

Vietnamese often leaves out the subject when it is obvious from context, especially in commands, signs, app instructions, game prompts, and manuals. So:

• Ghép ... rồi thoát ra. = Match ... and then exit.
• A fuller version could be Bạn hãy ghép ... rồi thoát ra. = You, please match ... and then exit.

In everyday Vietnamese, leaving out bạn is very normal in instructions.

Ghép basically means to join, combine, pair, match, put together.

In this sentence, it means something like:

• match
• pair
• connect

So Ghép bảng chữ cái với dãy số means match/pair the alphabet (or letters) with the number sequence.

This verb is common in exercises and puzzles, for example:

• ghép hình = put pieces together / assemble a picture
• ghép chữ = combine letters
• ghép đôi = pair up / match in pairs

Yes, bảng often means board, table, or chart. But bảng chữ cái is a fixed expression meaning alphabet.

Breakdown:

• bảng = chart/table/list
• chữ cái = letters of the alphabet

So literally it is something like the chart/list of letters, which naturally becomes the alphabet.

Depending on context, it may refer to:

• the alphabet in general
• an alphabet chart
• a set of letters shown on screen or on paper

So in a puzzle or app instruction, bảng chữ cái may feel a bit like the letters/alphabet chart rather than only the abstract concept alphabet.

Chữ cái means letter of the alphabet.

Examples:

• một chữ cái = one letter
• các chữ cái = the letters
• bảng chữ cái = the alphabet

A useful contrast:

• chữ can mean letter, writing, script, word depending on context
• chữ cái specifically means alphabet letter

So bảng chữ cái is not about words; it is about the letters themselves.

Với here means with.

It links the two things being matched:

• Ghép bảng chữ cái với dãy số
• Match the alphabet/letters with the number sequence

This is a very common pattern:

• ghép A với B = match/pair A with B

For example:

• Ghép từ với hình. = Match the words with the pictures.
• Ghép câu hỏi với câu trả lời. = Match the questions with the answers.

Dãy số means a sequence of numbers, number string, or series of numbers.

Breakdown:

• dãy = row, line, series, sequence
• số = number(s)

So:

• số = number / numbers
• dãy số = a sequence or ordered set of numbers

Using dãy số is more specific than just số. It suggests the numbers are presented as a connected series, not just random individual numbers.

Here rồi means then, and then, or after that.

It connects two actions in sequence:

1. Ghép bảng chữ cái với dãy số
2. thoát ra

So the meaning is:

• Match the letters with the numbers, then exit.

Important: this rồi is not the same as the rồi that marks a completed action in some contexts, such as:

• Tôi ăn rồi. = I already ate / I have eaten.

In your sentence, rồi is a sequencing word between two commands.

Both can be possible, but thoát ra often feels more complete and directional, like exit out, get out, or go out.

Breakdown:

• thoát = escape, get out, exit
• ra = out

So thoát ra emphasizes movement outward or leaving a screen/place/state.

In software or game contexts, this can mean:

• exit the current screen
• leave the game or menu
• back out

Sometimes Vietnamese uses a main verb plus a direction/result word like ra, vào, lên, xuống. These extra words often add nuance rather than creating a completely different verb.

No, not always. Vietnamese often adds words like ra, vào, lên, xuống after a verb to show direction, result, or completion, but whether they are required depends on the expression.

For example:

• đi ra = go out
• lấy ra = take out
• nói ra = say out loud / express
• thoát ra = get out / exit out

Sometimes the shorter form is still understandable:

• thoát can already mean escape/exit

But thoát ra sounds more explicit and natural in many situations.

Vietnamese does not use articles the way English does. There is no direct equivalent that must always appear for a/an/the.

So:

• bảng chữ cái can mean the alphabet, an alphabet chart, or the letters, depending on context
• dãy số can mean the number sequence or a number sequence

The context tells you which one is intended.

That is very normal in Vietnamese. Learners often want every noun to have a clear article, but Vietnamese usually leaves that information to context.

Yes, Vietnamese word order here is:

• Verb + thing 1 + với + thing 2

So:

• Ghép bảng chữ cái với dãy số = Match the alphabet with the number sequence.

You could reverse the two nouns and still get a very similar meaning:

• Ghép dãy số với bảng chữ cái

That would mean:

• Match the number sequence with the alphabet

In many matching exercises, the order does not change the overall task very much. But the original version presents bảng chữ cái as the first item to be matched.

Yes. Hãy can be added to make the instruction sound more explicitly imperative:

• Hãy ghép bảng chữ cái với dãy số rồi thoát ra.

This means something like:

• Please / go ahead and match the alphabet with the number sequence, then exit.

However, in instructions, menus, app prompts, and manuals, Vietnamese often leaves hãy out because the command meaning is already obvious. So the original shorter version sounds natural.

Yes, especially in a context like:

• a puzzle
• a phone app
• a game
• a software prompt
• written instructions

It is short, direct, and functional.

Depending on context, a native speaker might also say things like:

• Ghép chữ cái với dãy số rồi thoát ra.
• Ghép các chữ cái với dãy số rồi thoát ra.
• Nối chữ cái với dãy số rồi thoát ra.

The exact choice depends on whether the task is more like matching, joining, or connecting.

Sometimes, yes, but they are not always identical.

• ghép = match, pair, put together
• nối = connect, link, join

If the activity is a matching exercise, ghép is often better. If the activity is literally drawing lines between items, nối may sound more natural.

For example:

• Ghép chữ với hình. = Match the words with the pictures.
• Nối các điểm lại với nhau. = Connect the dots.

So in your sentence, ghép suggests pairing/matching, while nối would suggest more literal linking.

A few things can be tricky:

• ghép: the gh is used before certain vowels to keep a hard g sound.
• chữ: this has the ữ vowel and a tone, which can be hard for learners.
• dãy: the ãy combination and tone may be challenging.
• rồi: this has its own tone and should not be pronounced flat.
• thoát: watch the final t stop.
• ra: simple in spelling, but keep it clear and separate from the previous word.

Also remember that Vietnamese is tonal, so correct tones matter a lot more than English stress patterns. English speakers often focus on syllable stress, but Vietnamese relies much more on tone and clear syllable pronunciation.
