IPA: /ˌɪn.təˈneɪ.ʃən/
KK: /ɪnˈtoʊneɪʃən/
The way in which a person's voice rises and falls in pitch while speaking, which can convey different meanings or emotions.
The teacher emphasized the importance of intonation in spoken language to help students understand the meaning behind the words.
Intonation is formed from "in-" (meaning into) and "tonare" (meaning to sound or to tone). The word refers to the rise and fall of the voice in speaking, essentially how one sounds when speaking.
Think of 'sounding' ('tonare') 'into' ('in-') a sentence — that's how intonation affects the way we speak.
