Intonation
noun /ˌɪntəˈneɪʃən/ — The rise and fall of the voice — the melody of speech that carries meaning beyond the words.
Definition
The rise and fall of the voice in speaking; the way in which pitch varies in speech to convey meaning and emotion; the action of intoning.
Beyond the definition
Intonation is meaning's invisible carrier — the same words said with different intonation become different statements. 'Really?' can be a question, a challenge, a compliment, or a rebuke. The words are identical; the intonation is everything.
Origin & history
From Medieval Latin intonare — to thunder, to intone (in: into + tonare: to thunder). The introduction of tone — making speech tonal, giving it the music of pitch variation.
