Corpus linguistics refers to large collections of natural language texts that can be analyzed using computational techniques. Creating corpora involves collecting and transcribing written or spoken texts, which is time-consuming. Well known corpora include the British National Corpus and the Lancaster-Oslo-Bergen Corpus. There are different types of corpora depending on the research questions or topics being investigated. Analyzing corpora can provide insights into patterns of language use across different text types and contexts. Teachers and material developers can use corpus analyses to inform instruction and claims about linguistic features.
