Did You Know?
The spelling of sully has shifted several times since it was sylian in Old-English, but its meaning has remained essentially the same: "to soil." If you're looking for other words that mean "to soil," you can try out befoul, besmirch, blacken, foul, grime, stain, or simply dirty. You might wonder if the English word sullen (meaning "gloomy or morose") is a relative of sully, and the answer is no. Sullen traces back by way of Anglo- and Old French to Latin solus, meaning "alone."
