"Sygaldry, simply put, is a set of tools for channeling forces. Like sympathy made solid."
-Kvothe,The Name of the Wind
Sygaldry is a discipline of magical study taught at the University under the heading of Artificery. Sygaldry involves the use and application of runes, which create effects similar to a permanent form of sympathy . There are 197 runes, and they can be used in a variety of combinations to perform a wide assortment of effects on various materials.
Sygaldry can be used in a multitude of ways, the most common example of sygaldry are sympathy lamps, which converts ambient heat in the environment into light. other uses include; Light Emitters, the Bloodless, coolers, simultaneous bells, and many other items that generally affect some part of life.
Kvothe claims to have learned all of the runes in seven days, a process that takes most students at least a month. Part of his ability to accomplish this can be attributed to a mnemonic song he created himself to help learn them.
Ule and doch are Both for binding Reh for seeking Kel for finding Gea key Teh lock Pesin water Resin rock
Above is the portion of the rhyme he relates in the Chronicle.
