wǒ bù chī làjiāo.

Chinese basic word order is often Subject + Negation/Adverb + Verb + Object, so:

• 我 = I
• 不 = not / don’t
• 吃 = eat
• 辣椒 = chili peppers

So 我不吃辣椒 is literally I not eat chili peppers. Chinese does not need the extra English helping verb do.

不 is the standard word used to negate many verbs in Chinese, and it usually goes directly before the verb:

• 不吃 = do not eat
• 不喝 = do not drink
• 不去 = do not go

So 我不吃辣椒 follows a very common pattern.

It can often mean either one, depending on context.

Without extra time words, Chinese sentences are often more flexible than English:

• 我不吃辣椒 can mean I don’t eat chili peppers as a general habit or preference.
• In the right situation, it can also mean I’m not eating chili peppers.

If you want to make the time clearer, Chinese usually adds context words:

• 我今天不吃辣椒。 = I’m not eating chili peppers today.
• 我平常不吃辣椒。 = I usually don’t eat chili peppers.

辣椒 literally means chili pepper(s).

However, learners should know that in real life, someone saying 我不吃辣椒 may sometimes be understood as I don’t eat dishes with chili peppers. Still, it is more specific than saying I don’t eat spicy food.

If you want to say I don’t eat spicy food more generally, people often say things like:

• 我不吃辣。 = I don’t eat spicy food.
• 我不能吃辣。 = I can’t handle spicy food.

Chinese nouns usually do not change form for singular vs. plural the way English nouns do.

So 辣椒 can mean:

• chili pepper
• chili peppers
• chili as a food ingredient in general

The exact number depends on context. If you want to be specific, you add a number and usually a measure word:

• 一个辣椒 = one chili pepper
• 两个辣椒 = two chili peppers

In 我不吃辣椒, the noun is being used in a general sense, so no number is needed.

Measure words are usually needed when you are counting or pointing to a specific quantity:

• 一个辣椒 = one chili pepper
• 三个辣椒 = three chili peppers

But in 我不吃辣椒, you are speaking about chili peppers in general, not counting them. So no measure word is needed.

A natural pronunciation tip:

• 我 is third tone: wǒ
• 不 is fourth tone here: bù

Because 我 is followed by another syllable, native speakers often do not pronounce it with a full deep dipping third tone. It is often pronounced more like a low tone in connected speech.

So 我不 often sounds smoother and lighter than careful dictionary-style pronunciation might suggest.

Also, 不 changes tone only before another fourth-tone syllable. Since 吃 is first tone, it stays bù, not bú.

不 normally has fourth tone: bù.

It changes to bú only when the next syllable is also fourth tone.

Examples:

• 不是 → bú shì because 是 is fourth tone
• 不要 → bú yào because 要 is fourth tone

But in your sentence:

• 吃 is first tone: chī

So it stays:

• 不吃 = bù chī

Not exactly. 不 usually expresses do not / don’t, not cannot.

So:

• 我不吃辣椒 = I don’t eat chili peppers / I’m not eating chili peppers

If you want to say I can’t eat chili peppers, you would usually say:

• 我不能吃辣椒。 = I can’t eat chili peppers
• 我不能吃辣。 = I can’t eat spicy food

That can suggest a medical reason, low tolerance, or some other limitation, depending on context.

Yes, in conversation, if the subject is already clear, Chinese often drops it.

So:

• 不吃辣椒。 can mean [I] don’t eat chili peppers or [We/they/etc.] don’t eat chili peppers, depending on context.

But for learners, keeping 我 is very useful because it makes the sentence complete and clear.

Yes. 吃 is the normal verb for eating food, ingredients, and many edible things in general.

So all of these are natural:

• 吃米饭 = eat rice
• 吃面条 = eat noodles
• 吃辣椒 = eat chili peppers

Chinese often uses 吃 broadly, even when English might sometimes choose a different expression depending on context.

Yes, 我不吃辣椒 is natural and correct.

But depending on what you really mean, native speakers might choose slightly different expressions:

• 我不吃辣椒。 = I don’t eat chili peppers.
• 我不吃辣。 = I don’t eat spicy food.
• 我不能吃辣。 = I can’t handle spicy food.
• 我不喜欢吃辣椒。 = I don’t like eating chili peppers.

So your sentence is good, but the most natural version depends on whether you mean:

1. the actual ingredient chili peppers, or
2. spicy food in general.

Chinese does not use articles like a, an, and the the way English does.

So 辣椒 by itself can mean:

• chili pepper
• chili peppers
• the chili peppers
• chili peppers in general

The exact meaning depends on context. This is very normal in Chinese, and learners gradually get used to understanding it from the situation rather than from articles.
