KK: /ɛkstrəˈlɪŋɡwɪstɪk/
Referring to things that are not related to the study of language or linguistics.
The study of communication often includes extralinguistic factors such as body language and tone of voice.
Extralinguistic → It is formed from "extra-" (meaning outside) and "linguistic" (from Latin "lingua", meaning tongue or language). The word refers to elements that are outside of language itself, relating to communication beyond spoken or written words.
Think of 'extra-' meaning 'outside' and 'linguistic' relating to 'language' — this helps you remember that 'extralinguistic' refers to things that are outside of language.
