Sui generis database right
A "sui generis" database right is considered to be a property right, comparable to but distinct from copyright, that exists to recognise the investment that is made in compiling a database, even when this does not involve the "creative" aspect that is reflected by copyright.
Sincerity
According to the American Heritage Dictionary, the Latin word "sincerus" is derived from the Indo-European root "*sm̥kēros", itself derived from the zero-grade of "*sem" ("one") and the suffixed, lengthened e-grade of "*ker" ("grow"), generating the underlying meaning "of one growth", hence "pure, clean."
