IPA: //nɒnˈtoʊnəl//
KK: /nɑnˈtoʊnəl/
Describing something that does not have a tone or pitch, often used in the context of music or language.
The nontonal nature of the speech made it difficult to understand the intended meaning.
Nontonal → It is formed from "non-" (meaning not) and "tonal" (from Latin "tonus", meaning tone). The word "nontonal" means not relating to tone or lacking tone.
Think of 'non-' meaning not, and 'tonal' relating to tone — so nontonal describes something that is not related to tone.
