qǐng gěi wǒ kuàizi.

Here is the basic breakdown:

• 请 = please here; it makes the request polite
• 给 = give
• 我 = me
• 筷子 = chopsticks

So the sentence follows this pattern:

请 + 给 + recipient + thing

In other words, Mandarin is literally saying something like Please give me chopsticks.

Because with 给, Mandarin normally puts the person receiving something before the thing being given:

给 + 人 + 东西
= give + person + thing

So:

• 给我筷子 = give me chopsticks

Not:

• 给筷子我 — this is not the normal order

A more advanced alternative pattern does exist, such as 把筷子给我, but for this sentence the normal order is 给我筷子.

Mandarin does not have articles that work like English a/an/the.

So a bare noun like 筷子 can mean different things depending on context:

• chopsticks
• the chopsticks
• some chopsticks

If the situation is clear, Mandarin often leaves that kind of information unstated.

So 请给我筷子。 is perfectly understandable even without an article word.

Often, yes, especially if you mean one set/pair of chopsticks.

A very natural way to say this is:

请给我一双筷子。

Why 双? Because chopsticks are normally thought of as a pair.

So:

• 一双筷子 = one pair of chopsticks
• 一根筷子 = one chopstick stick

The original sentence without a measure word is still understandable, but 一双 often sounds more complete and natural in everyday situations.

Usually 筷子 refers to chopsticks as the utensil in general, often understood as a pair/set in context.

If you want to be specific:

• 一根筷子 = one chopstick
• 一双筷子 = one pair of chopsticks

So in 请给我筷子。, most people would understand that you want a usable set of chopsticks, not just one stick.

It is grammatical and understandable, and 请 does make it polite.

However, in real life, many speakers would say something a little more natural or complete, such as:

• 请给我一双筷子。
• 麻烦给我一双筷子。
• 请给我拿一双筷子。

Why? Because asking for 筷子 by itself can sound slightly abrupt or textbook-like. Adding 一双 makes the request clearer.

So the original sentence is fine for learning the pattern, but in daily use 请给我一双筷子。 is usually better.

Because this is a command/request sentence, and Mandarin often leaves out the subject when it is obvious.

English also does this:

• Give me the chopsticks.

We do not usually say:

• You give me the chopsticks.

Mandarin works similarly. So 请给我筷子。 does not need 你.

You could say 请你给我筷子。, but that can sound more pointed or emphatic, and it is not necessary in most situations.

No. 请 has more than one use in Mandarin.

Common meanings include:

• please
• to invite
• to treat someone to a meal or event

For example:

• 请坐。 = please sit
• 我请你吃饭。 = I’ll treat you to a meal / I invite you to eat

In 请给我筷子。, 请 is the polite please use.

筷子 is pronounced kuài zi.

Important points:

• kuài has a fourth tone
• zi is usually a neutral tone, so it is light and unstressed

So it is not pronounced like two equally strong syllables. The second syllable is weaker:

• kuài zi

This neutral-tone pattern is very common in words ending in 子.

The dictionary tones are:

• 请 qǐng = 3rd tone
• 给 gěi = 3rd tone
• 我 wǒ = 3rd tone
• 筷 kuài = 4th tone
• 子 zi = neutral tone

So the citation form is:

qǐng gěi wǒ kuài zi

In natural speech, a string of third tones does not sound exactly like three full dipping tones in a row. Earlier third tones usually change in connected speech, so the sentence sounds smoother than the dictionary tones suggest.

For a beginner, the most important things are:

• learn the dictionary tones first
• remember that 子 is neutral
• do not try to make every third tone a full deep dip in fast speech

Normally, no. That sounds like English word order copied into Mandarin.

In Mandarin, 请 usually goes before the verb phrase:

• 请给我筷子。
• 请给我一双筷子。

Putting 请 at the end is not the normal way to make a polite request in Mandarin.
