变坏

§ Understanding 变坏 (biànhuài)

Okay, let's talk about 变坏 (biànhuài). This word is pretty straightforward, and you'll hear it a lot when people are talking about food. Basically, it means 'to spoil' or 'to go bad'. Think of food that's no longer fresh or safe to eat. That's when you use 变坏.

DEFINITION

To spoil; to go bad (food).

§ How to use it in a sentence — grammar, prepositions

The grammar for 变坏 is quite simple because it's a verb phrase. You usually put it right after the subject. There aren't any tricky prepositions you need to worry about with 变坏 itself. It functions directly as the action.

• Basic structure: Subject + 变坏 (biànhuài)

This is the most common way you'll use it. Just state what's gone bad, then add 变坏.

Translation hint: These fruits all went bad.

Translation hint: Milk will go bad if it's left in the fridge too long.

• Adding particles for completion or change of state: Subject + 变坏 (biànhuài) + 了 (le)

The particle 了 (le) is very common with 变坏. It indicates that the action of 'going bad' has already happened or that there's a change of state. In most cases, if you're stating that something *is* spoiled, you'll use 了.

Translation hint: The meat has already gone bad, you can't eat it.

Translation hint: The refrigerator broke, and a lot of food went bad.

• Negative form: Subject + 没 (méi) + 变坏 (biànhuài)

To say something hasn't gone bad, you use 没 (méi) before 变坏. Don't use 不 (bù) here, as 没 is for negated completed actions or states.

Translation hint: These eggs haven't gone bad yet, you can still eat them.

Translation hint: Although the weather is hot, the food hasn't gone bad.

When you're talking about food going bad in Chinese, 变坏 (biànhuài) is a good word to know. But like in English, there are other ways to say it depending on what exactly you mean. Let's look at 变坏 and some similar words, so you know which one to use.

§ 变坏 (biànhuài): To Spoil, To Go Bad (General for Food)

变坏 (biànhuài) is a very common and versatile word for when food spoils. It's a general term, much like 'go bad' or 'spoil' in English. You can use it for almost any kind of food that is no longer fresh or edible.

DEFINITION

To spoil; to go bad (food).

§ 坏了 (huài le): Spoiled, Broken (Result State)

坏了 (huài le) is often used to describe the *state* of something being spoiled or broken. While 变坏 (biànhuài) emphasizes the *process* of going bad, 坏了 (huài le) focuses on the *result*. You'll hear this a lot.

DEFINITION

To be spoiled; to be broken (often implies a result).

§ 馊了 (sōu le): Sour, Spoiled (for Cooked Food/Rice)

When specifically talking about cooked food, especially rice or soups, that has gone sour or fermented, 馊了 (sōu le) is the perfect word. It implies a sour smell and taste.

DEFINITION

To go sour; to spoil (cooked food, rice).

§ 腐烂 (fǔlàn): To Rot, To Decompose (for Organic Matter)

腐烂 (fǔlàn) is a stronger word, meaning 'to rot' or 'to decompose'. It's used for organic matter that has broken down significantly, often with visible signs of decay like mold or mushiness. You might use it for fruit, vegetables, or meat that has been left for a very long time.

DEFINITION

To rot; to decompose.
