stupidity は stupid「愚かな」に抽象名詞語尾 -ity が付いた語で、判断力を欠いた愚かさや、その結果としての愚行を指します。語源はラテン語 stupere「ぼう然とする」で、頭が止まった状態を思い浮かべると覚えやすいです。sheer stupidity や act of stupidity の形で使われ、folly より日常的で批判の響きが強いです。
Think of stupidity as the state that comes from being stupid: stupid + -ity. The ending -ity often turns an adjective into a noun for a quality or condition. So stupidity is not just lack of intelligence in general, but often a foolish act or decision that shows poor judgment.

stupidity の語源・成り立ち Etymology
stupidity は stupid + -ity「性質」。stupid はラテン語 stupere「ぼうぜんとする・感覚が鈍る」から来ており、元は単なる馬鹿さより「頭が働かず固まる鈍さ」が中心です。stupor や stupefy も同根で、この語の重たい響きを支えています。
"Stupidity" comes from "stupid" plus the noun suffix "-ity," meaning a state or quality. "Stupid" goes back to Latin "stupere," meaning to be numb, stunned, or amazed. So the older idea was not just lack of intelligence, but a kind of mental dullness or frozen thinking, seen also in related words like "stupor" and "stupefy."
