How to pronounce Ronacher

Ronacher is most commonly pronounced "roh nah ker" (/ˈroʊnɑːkər/). This is the widely-used reading among engineers, though edge cases exist.

Armin Ronacher is the Austrian developer behind Flask and Jinja, now at Sentry, whose essays on agentic coding are HN front-page staples. The surname is German: the 'ch' follows a back vowel, so it is the ach-Laut (the throat sound in Scottish 'loch'), which English speakers render as a /k/ — ROH-nah-ker with stress on the first syllable, never the English 'ch' of 'church' and never a 'sh'. Anglophones routinely mangle it (the top user entry on howtopronounce.com is 'rah-nashur'), and on Rustacean Station the host had to stop and ask him how to say it.

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.
