IPA: /nɒnˈfəʊnɛtɪk/
KK: /nɑnˈfoʊnɛtɪk/
Not relating to the sounds of speech or not representing sounds in a straightforward way.
The word 'nonphonetic' describes languages that do not have a direct correspondence between letters and sounds.
Nonphonetic → It is formed from "non-" (meaning not) and "phonetic" (from Greek "phonetikos", meaning relating to sound). The word "nonphonetic" describes something that is not related to or does not represent sounds, particularly in the context of writing systems that do not correspond to spoken language.
Think of 'non-' meaning 'not' and 'phonetic' relating to 'sound' — so nonphonetic means something that does not relate to sound.
