Although no longer associated with magic, “fascinate” comes from a Latin root meaning a spell or witchcraft.  Specifically, “fascinate” denotes removal of the ability to resist.  I heartily recommend Dr. Tom Shippey’s thoughts on riddles and the dance they weave between truth, meaning, and obfuscation.  I might need to create our own word – legerdelangue, the sleight-of-words equivalent to legerdemain.  And now we know more about the weakness of dragons.
