Dash vs. Underscore: Know the Difference
By Shumaila Saeed & Hifza Nasir || Published on April 28, 2024
A dash (–) connects or separates words and phrases for clarity, while an underscore (_) is used in digital contexts to connect words, especially in usernames and email addresses.
Key Differences
A dash, often used in writing, serves to connect or separate words and phrases, enhancing readability and providing emphasis. It comes in various forms like the em dash (—) and en dash (–), each with specific uses, such as indicating ranges or interruptions. On the other hand, the underscore, found primarily in digital contexts, links words in situations where spaces are not allowed or recommended, such as in usernames, email addresses, and programming.

While dashes are integral to punctuation in English, contributing to the structure and flow of sentences, underscores do not traditionally belong to punctuation. Instead, they are a typographical convention that has become essential in digital communication and coding languages, ensuring clarity and continuity in identifiers and addresses.

Dashes can introduce additional information or indicate pauses stronger than a comma but less final than a period. They're versatile in formal and informal writing, bridging thoughts or setting off amplifications. Conversely, underscores connect words without implying pauses or additional information, purely serving a functional role to create readable and web-friendly text strings.

In terms of appearance, dashes are visibly distinct in printed and written text, contributing to the visual rhythm of sentences. The underscore, while less visible in running text, is indispensable in electronic addresses and coding environments, where it ensures the integrity of URLs, variables, and technical identifiers without spaces.
