Etymology of sillier
“Silly” comes into modern English from the Middle English word “silly,” which developed from earlier forms associated with the Old English word “sælig,” meaning happy or fortunate. Over time, the word’s meaning shifted from happiness or blessedness toward foolishness, perhaps through the idea of someone who is unusually innocent, naive, or impractical. The modern comparative “sillier” follows the regular English pattern of adding “-er” to short adjectives.
