What is hyphenation
Hyphenation is the use of hyphens to join words or parts of words. It plays a crucial role in writing, ensuring clarity and readability.
In compound terms like 'check-in', the hyphen clarifies relationships between words. It also assists in breaking words at line ends, preserving flow and understanding, such as in 'tele-communication'. Hyphenation rules vary; some words lose their hyphens with common usage (e.g., 'email' from 'e-mail'). It's an evolving aspect of language, with guidelines differing across style manuals. Understanding hyphenation improves writing quality, making it an indispensable tool in effective communication.
