arbitrary
Something is arbitrary if it is chosen randomly rather than for a specific reason.
Explanation at your level:
If you choose something for no reason, it is arbitrary. You might pick a color because you like it today, but not because it is the best color. It is just a random choice.
An arbitrary choice is one made without a plan. If a teacher says 'everyone must stand up' for no reason, that is an arbitrary rule. It can feel a bit strange or unfair to others.
When you describe a decision as arbitrary, you mean it was not based on facts or logic. It is often used in business or school to criticize rules that seem to have no purpose. It is a useful word for expressing frustration with unfair systems.
The term arbitrary is frequently used to discuss power and authority. When someone in a position of power makes an arbitrary decision, they are acting on their personal whim rather than following established guidelines. It highlights a lack of accountability.
In advanced discourse, arbitrary often describes symbols or linguistic signs. For example, language itself is arbitrary because the word 'dog' does not actually look or sound like a real dog; we just agreed to call it that. This highlights the distinction between inherent meaning and social convention.
At the C2 level, we explore the philosophical implications of arbitrary systems. In mathematics and logic, an arbitrary element is one chosen from a set without specific criteria. This usage underscores the difference between 'randomness' and 'selection'. Historically, the word has transitioned from describing the 'absolute power of a sovereign' to the 'randomness of a choice', reflecting a cultural shift toward rationalism and the demand for evidence-based decision-making in governance and science.

- Arbitrary means based on random choice rather than logic.
- It is often used to describe rules or decisions that seem unfair.
- The noun form is 'arbitrariness' and the adverb is 'arbitrarily'.
- It comes from the Latin word for a judge.
When we call something arbitrary, we are usually pointing out that it lacks a solid foundation in logic or rules. Imagine you have to pick a winner for a contest, but instead of checking who did the best work, you just pick the person wearing a blue shirt. That decision is arbitrary because it is based on a random, personal whim rather than a fair system.
In daily life, we often use this word to describe rules that feel pointless. If a teacher says you can only use blue pens, and there is no reason for that rule, you might call it an arbitrary rule. It is a powerful word because it signals that something feels disconnected from fairness or necessity.
The word arbitrary comes from the Latin word arbiter, which means a judge, witness, or someone who has the power to decide. An arbiter was someone who could settle a dispute based on their own judgment rather than a strict law.
Over time, the word evolved into the French arbitraire before entering English in the 14th century. Originally, it was used to describe power that was absolute—meaning a ruler could do whatever they wanted. Eventually, the meaning shifted to describe choices that are random or capricious, moving away from the idea of a 'judge' and toward the idea of 'randomness'.
You will most often hear arbitrary in professional or academic contexts. It is frequently used with nouns like decision, rule, choice, or detention. For example, 'The manager made an arbitrary decision to change the schedule.' It carries a slightly negative tone because it implies that the person in charge is acting without considering others.
In more casual settings, you might hear people say, 'That's so arbitrary!' when they feel frustrated by a situation that doesn't make sense. It is a great word to use when you want to sound precise about why a situation feels unfair or disorganized.
While 'arbitrary' isn't part of many set idioms, it is often used alongside phrases like at the drop of a hat (doing something suddenly) or by whim. Here are five ways to express the concept of randomness:
- On a whim: Doing something spontaneously without planning.
- At random: Choosing without a specific pattern.
- Capricious nature: Describing someone who changes their mind constantly.
- Shot in the dark: A guess made with no information.
- Wild card: Something that is unpredictable and can change everything.
Arbitrary is an adjective. It does not have a plural form. To make it an adverb, we add 'ly' to get arbitrarily. The stress is on the first syllable: AR-bi-trer-ee.
In the UK, the pronunciation is often /'ɑːbɪtrəri/, while in the US, it is /'ɑːrbɪtrɛri/. It rhymes with words like contrary or military. Remember that it is a four-syllable word, though in fast speech, the middle 'i' is often dropped, making it sound like 'ar-bi-tree'.
Fun Fact
It originally referred to a judge's power to decide something based on their own wisdom.
