Boredom → It is formed from "bore" (from Old English "borian", meaning to pierce or drill) and the suffix "-dom" (meaning state or condition). The word "boredom" refers to the state of being bored, which originally relates to the feeling of being pierced by a lack of interest or engagement.
Think of the feeling of being 'pierced' by a lack of interest — that's what 'boredom' means, the state of feeling bored.
