As a noun, “code” is a system of symbols, rules, or words used to represent information, like computer code or secret messages. As a verb, it means to write instructions for computers or to put information into a coded form.
“Code” comes from French “code,” from Latin “codex” or “caudex,” meaning “tree trunk” and then “book” or “written law.” It originally referred to written legal rules before expanding to any systematic set of symbols.
