Lexicographer → It is formed from "lexicon" (from Greek "lexikon", meaning word or dictionary) and "-graph" (from Greek "grapho", meaning to write). A lexicographer is someone who writes or compiles a dictionary of words.
Think of a 'word' ('lexicon') being 'written' ('graph') — that's what a lexicographer does, they write words into a dictionary.
