Old English 'sælig' meant 'blessed, happy, fortunate' — a thoroughly positive term derived from Proto-Germanic *sælīgaz, itself from *sæliz meaning 'luck, happiness.' ThePIEroot is *sel- (happiness, goodness). The semantic journey of 'silly' is one of the most dramatic pejoration sequences in English. In

The Unseelie Court of Scottish fairy lore — the dark, malevolent fairies — takes its name directly from *un-seely*, meaning 'unblessed'. This means the word 'silly' is embedded in Scottish supernatural mythology: the good fairies were the Seely Court, the blessed ones. Every time you call something silly, you are reaching back to a taxonomy of fairies and a theological vocabulary
around the 13th–14th centuries: the innocent and simple became associated with the helpless and pitiable — 'poor, wretched, deserving of compassion.' This 'innocent simplicity → pitiable helplessness' step is key. By the 15th century, 'seely' meant feeble, frail, and weak-minded. By the 16th century (attested by 1576 in Sidney's works), 'silly' had acquired the sense of 'lacking in judgment, feeble-minded.' The modern sense of 'absurd, frivolous, foolish' is attested by the 17th century. Cognates sharing *sel- include German 'selig' (blessed, blissful), Dutch 'zalig' (blessed), Old Norse 'sæll' (happy), and Gothic 'sels' (good, kind). Scholars including the OED editors and Anatoly Liberman have traced this pejoration as a sociolinguistic phenomenon: the religiously humble became socially pitied, then intellectually dismissed. Key roots: *sel- (Proto-Indo-European: "happiness, goodness; propitious"), *sælīgaz (Proto-Germanic: "blessed, happy, fortunate"), *sæliz (Proto-Germanic: "luck, happiness, good fortune").
