The word "scornfulnesses" is spelled with three consecutive syllables that end in "-nesses". The first two syllables contain the consonant cluster "rn" which is pronounced as a retroflex nasal sound. The vowel sound in each syllable is a schwa [ə], which is a neutral vowel sound that makes the syllables sound similar. The final syllable has a long "e" sound and is pronounced as '-nesses' which means qualities of scornfulness, having a disdainful or contemptuous attitude towards someone or something.
The word "scornfulnesses" is not recognized as a standard English word, and therefore, it does not have an established etymology. It appears to be a combination of the word "scornful" (expressing contempt or disdain) and the suffix "-ness" (used to form abstract nouns indicating a state or quality). However, it is worth noting that the usage of this word may be highly uncommon or potentially even non-existent.
