definition

Think of a definition as a boundary marker for language. When we use words, we need to make sure we are on the same page, and a definition acts as the anchor that keeps our communication steady.

In an academic sense, it is the process of setting limits on what a concept includes and excludes. Without clear definitions, arguments would be impossible to resolve because everyone would be using the same words to mean different things.

Outside of text, you might hear this word used to describe visual clarity. When you buy a high-definition (HD) TV, the word 'definition' refers to how crisp and clear the image is. It is all about how well you can distinguish the edges of an object!

The word definition has a long journey through history. It comes from the Latin word definitio, which is derived from definire, meaning 'to limit' or 'to set bounds.'

The prefix de- means 'completely,' and finire relates to finis, which means 'end' or 'boundary.' So, historically, defining something meant literally putting a fence around it to say where it ends and something else begins.

It entered Middle English through Old French in the 14th century. Interestingly, the sense of 'visual sharpness' didn't appear until much later, in the 19th century, as scientists began using the term to describe the clarity of lenses in microscopes and telescopes.

You will most often encounter definition in formal or academic contexts. It is a staple of essays, textbooks, and legal documents where precision is non-negotiable.

Common collocations include 'provide a definition,' 'clear definition,' and 'by definition.' Using the phrase 'by definition' is a great way to show that something is true simply because of what a word means.

While it is a neutral word, it carries a slightly formal register. In casual conversation, people might just ask, 'What does that mean?' rather than 'Can you give me a definition?'

By definition: Used to state that something is true as a logical result of a word's meaning. Example: 'A square is, by definition, a rectangle with four equal sides.'

Defy definition: To be so strange or complex that it cannot be easily described. Example: 'The beauty of the sunset defied definition.'

Broad definition: A way of looking at a concept that includes many things. Example: 'He has a broad definition of what counts as a sport.'

Strict definition: A very narrow or exact way of interpreting something. Example: 'Under a strict definition, this isn't a crime.'

Working definition: A temporary definition used for a project. Example: 'Let's use this as a working definition until we finish our research.'

The word definition is a countable noun. You can have one definition or many definitions. It is usually preceded by articles like 'a,' 'an,' or 'the.'

Pronunciation is straightforward but requires care with the stress. In both British and American English, the primary stress is on the third syllable: def-i-NISH-un. The IPA is /ˌdef.ɪˈnɪʃ.ən/.

Rhyming words include 'partition,' 'ambition,' 'tradition,' 'condition,' and 'ignition.' Notice how they all share that distinct '-ition' suffix, which is a common pattern for nouns describing an action or state.
