The word "arity" came up during lunch today in our group and our
resident mathematician asked whether the word was invented by
logic programming people or whether it was borrowed from another
field.  We looked it up in both a standard college English dictionary
and in a scientific and technical English dictionary and couldn't 
find the word "arity" in either of them.

Does anyone know where the origin of the word "arity"?

Thanks,
Dave Wahl
