Julius Caesar valued clarity and simplicity in language above all else, especially in writing and speech intended to persuade or command.
The most famous quote attributed to him on this topic comes from his criticism of overly ornate or complicated prose. According to ancient sources (particularly quoted later by writers like Cicero and Fronto), Caesar reportedly said:“Avoid an unusual word as you would a reef.”
(Latin: “Ut tamquam scopulum, sic fugias inauditum atque insolens verbum.”)
This line appears in a letter fragment preserved by Aulus Gellius and others, where Caesar was advising on rhetorical style. He believed that obscure, rare, or affected words were dangerous obstacles to understanding—just like hidden reefs are to a sailor.
Effective communication, in his view (especially for military orders, political speeches, and historical writing), required plain, direct, and familiar language that everyone could grasp immediately.
His own writing style in Commentarii de Bello Gallico (The Gallic War) reflects this perfectly: it is famously clear, straightforward, and unadorned—so much so that it became a model prose for centuries of Latin students.
In short: Caesar championed simple, precise, and accessible language as a tool of power and clarity. Fancy words were not just unnecessary—they were risky.
