How to pronounce Leiningen

Leiningen is most commonly pronounced "line ing un" (/ˈlaɪnɪŋən/). This pronunciation is documented by the project itself (see Leiningen official FAQ — "How do you pronounce Leiningen? It's LINE-ing-en. ['laɪnɪŋən]").

Leiningen (the lein command) is the long-standing build tool and project-automation entry point for Clojure. The official FAQ settles it: LINE-ing-en, with the German ei read as "eye" — the name comes from Carl Stephenson's short story "Leiningen Versus the Ants". Common misreadings like "lay-nin-jen" or "lee-nin-gen" are simply wrong.

Pronouncing project and product names correctly avoids the small but persistent friction of being gently corrected during standups, conference Q&As, and team calls. Hearing the word a few times locks in the right reading better than reading IPA ever will.
