sour
Sour describes a sharp, tangy taste like a lemon or something that has gone bad.
Explanation at your level:
Sour is a taste. Think of a lemon. Lemons are sour. If food is old, it can be sour too. Do not eat sour food if it is not supposed to be sour!
You use sour to describe food that is sharp or acidic. For example, vinegar and limes are sour. If you leave milk in the sun, it becomes sour and you should not drink it.
The adjective sour describes a specific taste profile. It is common to use it for citrus fruits or fermented foods like yogurt. We also use it to describe a person's mood when they seem unhappy or unfriendly.
Beyond the literal taste, sour is frequently used in figurative contexts. We might say a business deal has 'gone sour' if it fails. It carries a nuance of disappointment or a negative shift in circumstances.
In advanced usage, sour can describe a cynical or resentful attitude. It suggests a bitterness that influences how a person perceives the world. It is a powerful word to describe the degradation of relationships or institutional trust.
Etymologically, sour reflects the ancient human experience of spoilage and fermentation. In literary contexts, it may be used to evoke a sense of decay or moral bitterness, transcending its simple culinary definition to become a symbol of discontent.

The word sour has a very long history! It comes from the Old English word sur, which meant exactly what it means today: acidic or fermented.
It shares roots with the Proto-Germanic suraz and is related to the German word sauer. It is fascinating to see how these linguistic roots have stayed so consistent over thousands of years across different languages.
Historically, sour was often used in the context of brewing and fermentation. Since ancient humans relied on fermentation to preserve food, the concept of a 'sour' taste was central to survival and cooking. It is a word that connects us directly to the culinary habits of our ancestors.
You will hear sour used in many daily situations. In the kitchen, we talk about sour cream or sour dough, which are common culinary staples.
When talking about people, saying someone has a sour expression implies they look grumpy or displeased. It is a slightly negative word, so be careful using it to describe people's personalities!
In formal writing, you might see it used to describe a sour economy or a sour outlook, meaning things are not going well. It is a great way to add a bit of descriptive 'bite' to your sentences.
Idioms make language fun! Here are five common ones:
- Sour grapes: Pretending you don't want something just because you can't have it.
- Turn sour: When a situation or relationship becomes unpleasant.
- Leave a sour taste in one's mouth: To leave a bad memory or feeling after an event.
- Go sour: Similar to turning sour, often used for plans or milk.
- Sourpuss: A slang term for someone who is always grumpy or complaining.
Sour is a standard adjective. It does not have a plural form because it describes a quality, not an object.
Pronunciation-wise, in US English it is often pronounced as one syllable or a very quick diphthong: /saʊər/. In British English, it is often pronounced more like /ˈsaʊə/.
It rhymes with words like flower, power, hour, tower, and shower. Remember that it is usually followed by a noun, like 'a sour lemon', or used after a linking verb, like 'the milk tastes sour'.
