random
B1Pronunciation
UK
- /rˈændəm/
US
- /ˈrændəm/
Description
- happening by chance
- unpredictable
- arbitrary
Imagine throwing dice: the number you get is not planned. That's the core of what "random" means: something that happens by chance, without a clear pattern or reason. A truly random event cannot be predicted with certainty. You might pick a name from a hat, or end up sitting next to a stranger on a plane because the seats were assigned by chance. Sometimes the word also describes things that seem mixed up or without order, like a pile of toys scattered across the floor.
The word "random" describes something that happens without deliberate intention, a predictable pattern, or a clear cause. It suggests chance and unpredictability. Think about shuffling a deck of cards: each card could end up in many different positions, and you do not know in advance where a particular card will go.
"Random" can be used as an adjective to describe events ("a random encounter"), selections ("a random sample"), or even behavior ("his actions seemed completely random"). It's often contrasted with "systematic" or "intentional." For example, a scientist might use random sampling techniques to ensure their research isn't biased.
In modern usage, especially in computing and statistics, "random" also has more specific meanings. Computers often use algorithms to produce unpredictable-looking sequences. These are called pseudo-random number generators, and they are used for things like simulations, games, and cryptography. Even so, the everyday meaning stays the same: something happening by chance, without a clear reason or plan.
So whether it's a lucky lottery win, a surprising coincidence, or simply a messy collection of things, the idea is the same: it happens without intention or an obvious pattern.
