insidiousness

/ˌɪnˈsɪˌdiəsnəs/ noun

A surreptitious harmfulness, quality of entrapment, or treacherousness; the characteristic of being insidious.

Word Origin From Latin sedere 'to sit'. Insidious literally means 'sitting in or on' — like an ambush, waiting to pounce. The idea is something treacherous that sits hidden. The same root gives us sedentary (sitting a lot), sediment (stuff that settles at the bottom), and president (one who sits before others). The breakdown in+sid+ious+ness shows 'in-sit-ious-ness'.
