Metalinguistic → It is formed from "meta-" (meaning beyond or about) and "linguistic" (from Latin "lingua", meaning tongue or language). The word refers to the study or discussion about language itself, going beyond just using it.
Think of 'meta-' meaning 'about' and 'linguistic' relating to 'language' — so metalinguistic means discussing or thinking about language itself.
