History of Dash Symbols

The dash symbol dates back to early typography and medieval scripts. The hyphen appeared in handwritten manuscripts before being standardized in printed text. The en and em dashes evolved as typography developed in the 18th and 19th centuries. Over time, digital formats adapted these symbols for word processing, programming, and coding applications.

How to Use Dash Symbols Correctly

  • Hyphen: Use to form compound words and break words at line endings.
  • En Dash: Use for numerical ranges and relationships.
  • Em Dash: Use for strong sentence breaks or interruptions.
  • Avoid Overuse: Using too many dashes in a sentence can reduce clarity.
