Hyphenation is the management of word breaks (with a hyphen) wherever a word at the end of a line doesn’t fit. There are some rules about the usage of hyphenation, such as:

• position of the word-break in a word, which depends on the language and script;
• avoid it in capitalized words;
• avoid it in the last word of a paragraph or a column;
• avoid having more than three following lines with hyphens.
