Etymology

Origin of dictum

1660–70; < Latin: something said, a saying, command, word, noun use of neuter past participle of dīcere to say, speak; cf. index

Explanation

"You are what you eat" is a dictum, and so is a law requiring you to curb your dog. A dictum is a formal pronouncement, a rule, or a statement that expresses a truth universally acknowledged. Dictum dates from the 16th Century. It descended from a Latin word that means "something said." In contemporary use, it means more like "something that is officially said." If the principal of your school issues a dictum declaring "no jeans in school," it's time to go shopping.
