Coder → It is formed from "code" (from Latin *codex*, meaning a book or manuscript) and "-er" (meaning a person who). A coder is a person who writes or creates code, typically in programming or computing contexts.
Think of a 'code' as a set of instructions, and the '-er' indicates a person. So, a coder is someone who creates instructions or code.
