What does hyphenation mean?
Hyphenation is the use of a hyphen to join words or parts of words. It commonly appears in compound nouns and modifiers, such as “well-being” or “state-of-the-art,” and can clarify meaning by showing how the elements relate. Hyphens may also be inserted at the end of a line so that a word can continue on the next line, a practice known as line-end or automatic hyphenation. The conventions are not universal: British and US style guides sometimes prescribe different treatments, and individual publishers may maintain their own rules. As a result, consistent hyphenation is important in dictionaries, edited writing, and typography. The word can refer both to the process itself and to the specific pattern of hyphens used in a particular word or document.

Where does hyphenation come from?
The word derives from “hyphen,” which comes from Greek hyphén, a mark used to join words together. “Hyphenation” was formed in English by adding the suffix “-ation” to that root. The underlying Greek term referred to a written mark beneath words, while the English word developed into both the hyphen itself and the practice of joining compound words with it.
