IPA: //kənˈsɒnəntəl//
KK: /kɒnsəˈnætl/
Describing something that includes or is related to consonants, which are speech sounds that are not vowels.
In phonetics, consonantal sounds are essential for forming words.
Consonantal is formed from "con-" (meaning together) and "sonare" (meaning to sound) combined with the suffix "-al" (meaning relating to). The word refers to sounds that are produced together, specifically consonant sounds in speech.
Think of sounds that are produced 'together' ('con-') and relate to 'sounding' ('sonare') — that's why consonantal refers to the sounds of consonants.
