The superlative form of 'fey,' meaning most magical, otherworldly, or having an eerie, delicate quality.
From Old English 'fǽge' meaning doomed or fated, which evolved in Middle English to describe something magical or strange. The superlative form adds the '-est' suffix common in English comparatives. Over time, 'fey' came to mean ethereal or otherworldly rather than specifically doomed.
The word 'fey' is connected to the same root as 'fate' in other Germanic languages—there's something fateful about things that seem magical or destined to vanish, which is why fairy-tale creatures often have that delicate, fey quality.
