The study of how language relates to culture and other behaviors.
Metalinguistics helps us understand the connection between language and cultural practices.
Metalinguistics is formed from "meta-" (meaning beyond or about) and "linguistics" (from Latin "lingua", meaning tongue or language, and the suffix "-ics", which denotes a field of study). The term refers to the study of language and its properties beyond the language itself.
Think of 'meta-' meaning 'beyond' and 'linguistics' relating to 'language' — this helps you remember that metalinguistics is about studying language itself.
