This category contains articles with Middle Korean-language text. The primary purpose of these categories is to facilitate manual or automated checking of text in other languages.

This category should only be added with the {{Lang}} family of templates, never explicitly.

For example {{Lang|okm|text in Middle Korean (10th-16th cent.) language here}}, which wraps the text with <span lang="okm">. Also available is {{Lang-okm|text in Middle Korean (10th-16th cent.) language here}} which displays as Middle Korean: text in Middle Korean (10th-16th cent.) language here.
