The word “sincere”
has a very interesting derivation. It comes from the Latin sine cera,
which means “without wax”. You surely wonder what “without wax”
has to do with “sincerity” and the answer is quite a simple one.
dishonest potters in ancient times had a crack or flaw in the pots they
made, they filled the cracks in with wax and painted over them.
Naturally as soon as the new owner brought heat near the wax, it melted
and the crack was exposed.
Thus when we
finish our letters by writing “Yours sincerely” we are really
stating that there is no deception in our letter, or to go back to
ancient times, there is no wax that will melt.
