fearsome

The word "fearsome" is a native English formation, built from the Old English noun "fær," meaning "danger, peril, or sudden attack," which evolved into the modern word "fear." The suffix "-some" originates from Old English "-sum," meaning "characterized by" or "productive of." This suffix was commonly attached to nouns to create adjectives describing a quality or tendency, as seen in words like "tiresome" or "quarrelsome." Therefore, "fearsome" literally means "characterized by fear," initially describing something that inspires fear. Over time, its meaning broadened through hyperbole to also describe things that are merely very large or extreme, intensifying the quality rather than strictly causing terror.
