“Sincere” Does Not Mean “Without Wax”
A sincere apology feels honest and unforced. Originally, however, the word described something pure and uncorrupted.
It comes through French from the Latin sincerus, meaning “whole, clean, pure, unmixed, or genuine.” When sincere entered English in the sixteenth century, it could describe both an unadulterated substance and a person free from deceit.
The connection is easy to understand. Wine that had not been diluted was sincere because nothing false had been mixed into it. The same image was applied to human character: sincere feelings contained no hidden motive, hypocrisy, or pretense.
Over time, the physical sense of “pure” became uncommon, while the emotional sense flourished. Today, we speak of sincere gratitude, sincere concern, and sincere apologies—not sincere wine.
But the word’s exact ancestry contains a mystery. Its deeper Latin origin is uncertain. Some linguists connect it to ancient roots suggesting “one growth” or something whole and unmixed.
Here is the memorable surprise: the popular claim that sincere comes from Latin sine cera, meaning “without wax,” is almost certainly false. According to the legend, dishonest sculptors concealed cracks with wax, while flawless statues were sold “without wax.” It is a wonderful story—but respected etymological sources reject it because there is no historical evidence connecting the phrase to the word.
The genuine origin may be less theatrical, but its image remains powerful: to be sincere is to present your thoughts whole and unmixed—with nothing deceptive added. Merriam-Webster, Online Etymology Dictionary
