Did you know?

Fictitious is related to the Medieval Latin word fictīcius, meaning "artificial," "imaginary," "feigned," or "fraudulent." It was first used in English as an antonym for natural. For instance, a fake diamond would be referred to as a fictitious one. This use indicates the word's deeper Latin roots: fictīcius is from the Latin verb fingere, meaning "to mold, fashion, make a likeness of; pretend to be." Nowadays, fictitious is no longer used for physical things shaped by the human hand. Rather, it is typically used for imaginative creations or for feigned emotions.
