The word may be difficult to pronounce at first, but it accurately combines various elements of English spelling and pronunciation.
The word "incuriousnesses" is derived from the combination of the prefix "in-" meaning "not" or "without", the root "curious" meaning "eager to know or learn", and the suffix "-ness" indicating a state or quality. The suffix "-es" is added to make the word plural. Therefore, "incuriousnesses" refers to the plural form of the noun "incuriousness", which describes a lack of curiosity or interest in acquiring knowledge.
