Language families are groups of languages that are related to each other because they come from a common older language. The languages in such a family are similar in their vocabulary or structure.
For example, French and Spanish both come from Latin. Latin was spoken a long time ago, and some of the people who spoke it started to speak one way, saying, for example, for good: "bueno" while another group started saying "bon." Most words are said a little differently in Spanish and French, so the two are called different languages.
Most languages belong to a language family, but some languages do not. These languages are called Language isolates.
