What is hyphenation
Hyphenation is the process of dividing words across lines in print or on websites. It involves inserting hyphens (-) where a word breaks to continue on the next line.
Proper hyphenation improves readability by reducing the unevenness of word spacing and unnecessary large gaps. It also helps avoid confusion that may occur when part of a word carries over. Ideal hyphenation should break words according to pronunciation and syllables. Most word processors and publishing apps have automated tools to handle hyphenation effectively based on language rules and dictionaries. Though subtle, proper hyphenation improves overall typography and reading comfort.
