Etymology

The Oxford English Dictionary and most scholars state that sincerity from sincere is derived from the Latin sincerus meaning clean, pure, sound . Sincerus may have once meant "one growth" (not mixed), from sin- (one) and crescere (to grow). Crescere is cognate with " Ceres ," the goddess of grain, as in "cereal". 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 , hen
