Hi Msians,
Just came across the true meaning of sincere---
It is commonly believed that sincere comes from two Latin words - sine 'without' and cera 'wax'., both involving craftsmen, who during the Republic of Rome, would generally have been slaves or foreigners.
Some think that marble workers would cover imperfections in the stone with wax, much as modern homemakers or unscrupulous antique dealers might rub wax to hide a scratch in wood. Another idea for the origin of sincere has more ominous consequences. Since cement was more expensive than wax, unscrupulous brick layers would sometimes employ it -- at least that's the story.
When it melted, bricks could shift and structures collapse. So the claim that something was sine cera would be an important guarantee.
Hence the word SINCERE -
