Related languages are languages that share a common origin or have evolved from a similar linguistic ancestor. These languages often exhibit similarities in vocabulary, grammar, and pronunciation. For example, the Romance languages such as Spanish, French, and Italian all derive from Latin, making them related. Additionally, related languages can also arise from geographical proximity or cultural exchange. For instance, English and German are both part of the Germanic language family, sharing many linguistic features. Understanding related languages can help learners recognize patterns and make it easier to acquire new languages within the same family.
