How Do You Spell SMARTNESSES?
Pronunciation: [smˈɑːtnəsɪz] (IPA) 
The spelling of the word "smartnesses" may seem confusing at first, but it can be easily deciphered using IPA phonetic transcription. The word is pronounced /ˈsmɑːtnɪsɪz/, with the emphasis on the first syllable. The suffix "-ness" is added to the adjective "smart" to indicate the quality or state of being smart. The additional "-es" at the end of the word is used because "smart" ends in a voiceless consonant sound. Thus, "smartness" becomes "smartnesses" in the plural form.
