Corpora are large collections of written or spoken texts used for linguistic research and analysis. They can include various types of materials, such as books, articles, conversations, and social media posts. Researchers use corpora to study language patterns, vocabulary usage, and grammar in different contexts. These collections can be specialized, focusing on specific genres or languages, or they can be general, encompassing a wide range of texts. Linguists and language educators often rely on corpora to develop teaching materials, improve language models, and enhance understanding of language evolution and usage trends.
