Etymology

The word "boggle" originated in the 16th century, derived from the Middle English term "bogge," referring to a specter or hobgoblin. The frequentative suffix "-le" suggests a repeated action, implying the idea of being startled or hesitant—as if one were repeatedly encountering a frightening apparition. Over time, the meaning expanded to include mental hesitation or confusion, reflecting the unsettling effect of the supernatural on the human mind.
