poison
Poison is a dangerous substance that can make you very sick or cause death if it enters your body.
Explanation at your level:
Poison is a bad thing. It is not food. It is not a drink. If you touch poison, you can get very sick. Do not eat poison. It is dangerous. Always look for a warning sign on bottles at home.
A poison is a substance that can kill you or make you very ill. You find poison in some cleaning products or in nature, like in certain snakes or spiders. Keep these things away from children. It is important to be safe.
In English, poison refers to any substance that causes harm to a living organism. We often use it when talking about safety, such as 'rat poison' or 'poison ivy.' It can also be used figuratively to describe something that destroys a relationship or an environment, like 'the rumors were like poison to the team.'
The term poison is used both literally and metaphorically. Literally, it refers to toxic substances that require medical attention if ingested or touched. Metaphorically, we use it to describe toxic behavior or environments that are damaging to people's well-being. It is a powerful word that signals danger or severe negativity.
Beyond its primary biological definition, poison is frequently employed in political and social discourse. To 'poison the well' is a sophisticated way of describing the act of preemptively damaging someone's reputation. Furthermore, in literature, it is often used as a motif for corruption or moral decay. Understanding the nuance between 'toxic' (which is often used as an adjective) and 'poison' (the noun) is key for advanced speakers.
Etymologically, the evolution of poison from the Latin potio—a simple drink—to its current status as a synonym for lethality is a profound linguistic journey. In high-level discourse, the word carries connotations of betrayal, malice, and irreversible damage. Whether discussing the 'poisoning of a legacy' or the 'poison of political polarization,' the word serves as a potent metaphor for systemic destruction. Its usage requires an awareness of its gravity; it is rarely used lightly in formal or academic writing.

Hey there! Let's talk about the word poison. At its core, it refers to any substance that is harmful to living things. Think of things like cleaning chemicals, certain plants, or even snake venom.
When we say something is a poison, we mean it has the power to cause illness or death if it gets inside or on a body. It's a word that demands caution and respect, which is why you see warning labels with skulls on them!
But it's not just about liquids or chemicals. Sometimes people use the word to describe something negative in a figurative way, like a poisonous attitude that ruins a group's mood. It's a versatile word, but always carries a heavy meaning.
The history of the word poison is actually quite fascinating. It comes from the Old French word poison, which meant 'a drink' or 'a potion,' but specifically one that could be magical or medicinal.
Going back even further, it traces back to the Latin word potio, which simply means 'a drink.' Isn't it wild how a word for a regular drink evolved to mean something so deadly? It shows that in ancient times, the line between a healing medicine and a lethal dose was often just a matter of quantity.
By the 13th century, the meaning had shifted in English to refer specifically to a 'deadly potion.' It lost its neutral 'drink' meaning and became synonymous with danger. It's a great example of how language changes over time to reflect human fears and experiences.
You'll mostly hear poison used in serious, factual, or cautionary contexts. Common collocations include rat poison, deadly poison, or poison ivy. It’s a noun that acts as a strong warning.
In formal settings, like in a science lab or a legal document, it is used precisely to identify toxic substances. In casual conversation, you might use it to describe something you really dislike, though that's a bit dramatic!
Remember that poison is usually a countable noun, but it can also be used as a verb (e.g., 'to poison the water supply'). Always be careful when using it—it's not a lighthearted word!
Idioms help us express complex ideas using simple words. Here are five common ones:
- Pick your poison: Used when asking someone to choose between two unpleasant options. 'We can either walk in the rain or wait an hour for the bus; pick your poison.'
- Poison the well: To spread negative information about someone to prevent others from trusting them. 'He tried to poison the well before the meeting started.'
- Slow poison: Something that causes harm gradually over a long period. 'His constant negativity is a slow poison to our friendship.'
- Poison pen: Referring to a letter or note written to cause harm or insult. 'She received a poison pen letter from an anonymous source.'
- What's your poison?: A casual, slightly cheeky way to ask someone what they want to drink (usually alcohol). 'I'm heading to the bar, what's your poison?'
The word poison is a two-syllable word, pronounced /ˈpɔɪzən/ in both British and American English. The stress is on the first syllable: POI-zon.
As a noun, it is countable (a poison, many poisons). It is often preceded by articles like 'a' or 'the'. As a verb, it follows standard conjugation: poison, poisons, poisoned, poisoning.
It rhymes with words like foison (a rare word) and shares similar phonetic structures with words like reason or season, though the vowel sounds are distinct. Keep an eye on that 'z' sound in the middle—it's a voiced consonant!
