Underscore vs. Hyphen: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Updated on October 8, 2023
An underscore (_) is a horizontal line used to separate or emphasize; a hyphen (-) connects words or parts of words.

Key Differences
The underscore (_) and hyphen (-) are typographic symbols used for different purposes in written language. An underscore is a horizontal line that typically appears beneath text and is often used in computing to represent spaces in file names and web addresses, allowing text to be unbroken. On the other hand, a hyphen is primarily used in English grammar to connect words or parts of words, such as compound adjectives and compound words, to avoid ambiguity.

Underscore, by being a symbol that separates or emphasizes content, often sees utilization in programming and web development. It helps create clear, machine-readable strings and identifiers where spaces are not allowed. In contrast, the hyphen, with its grammatical function, aims to make human reading clearer and more understandable by showing the connection or relation between words, ensuring coherence and smooth reading flow.

Even within informal contexts, underscore and hyphen maintain their distinct uses. Underscores are frequent in email addresses and usernames, where spaces may lead to errors or misconceptions. Meanwhile, hyphens serve in informal writing to unite words, creating understandable and well-formed structures, like in compound nouns, ensuring clarity and correct interpretation.

Underscores are also employed to create visual separation in written text, without changing the meaning, often acting as a substitute for spaces or as a tool for emphasis in handwritten texts. Hyphens have an established role in dividing words at the end of a line of text, aiding in text alignment and avoiding awkward text breaks, thereby enhancing the readability of the text.
