Lack of diligence or careful attention; the opposite of assiduity or persistent hard work.
From dis- + assiduity (from Latin assiduus, meaning constantly present or diligent). This extremely rare word theoretically means the absence of the careful, persistent attention that 'assiduity' describes.
This word is so obscure that it barely appears in any modern dictionary—it's a perfect example of how English theory allows for infinite word creation, but actual speakers prefer simpler words like 'laziness' or 'neglect.'
