Usage

What is a basic definition of odd? Odd refers to a number that will have a remainder of 1 when divided by 2. Odd also describes something that is unusual or weird. Odd has many other senses as an adjective and a few as a noun. An odd number is any number that has a remainder of 1 when it’s divided by 2. For example, 7 divided by 2 is 3 with a remainder of 1. 7 is an odd number. On the other hand, 8 divided by 2 is 4 with no remainder. A number, such as 8, that has no remainder when divided by 2 is called an even number. Real-life examples: 5, 11, 37, and 649 are examples of odd numbers. Used in a sentence: I always like to cut my pizzas into an odd number of slices. Odd also describes something that is unusual or not what a person would expect. Real-life examples: People often make odd choices or odd decisions that catch other people by surprise. For example, it might be considered odd to go swimming in regular clothing because people usually wear a bathing suit. A firefighter showing up to a fire in an ice cream truck would be odd because they are expected to drive fire trucks, which have firefighting tools. Used in a sentence: They were caught off guard by the man’s odd choice of words. Odd can also refer to something that is very strange, weird, or bizarre. Real-life examples: Works of fantasy like the Harry Potter series often include very odd creatures, such as plant monsters or giant, flying jellyfish. In everyday life, people may display odd behavior, such as walking on their hands down the street. Used in a sentence: The circus clown drove an odd car that was shaped like a giant pie.

Etymology

Origin of odd¹

First recorded in 1300–50; Middle English odde, from Old Norse oddi “odd (number)”

Origin of ODD²

First recorded in 1980, in the third edition of the Diagnostic and Statistical Manual of Mental Disorders

Explanation

The numbers 1, 3, 5, and 35 are all odd numbers — they can't be divided by two. They are not even. Also, things that are weird or strange are called odd. This word covers things that are slightly off-kilter, like odd numbers. You can use odd for a single thing that belongs in a pair, like an odd sock or odd mitten. If someone wants you to do odd jobs, that could mean almost anything: odd jobs are random and unpredictable jobs that could come up. When you describe a person as odd, or that they’re exhibiting odd behavior, it means they're peculiar and out of the ordinary.
