Zephyr is most commonly pronounced "zeffer" (/ˈzɛfər/). This is the widely-used reading among engineers, though edge cases exist.
Zephyr is the Linux Foundation's small-footprint RTOS for microcontrollers, and the default runtime behind Nordic's nRF Connect SDK plus growing Espressif and ST support. It is pronounced ZEF-ur (/ˈzɛfər/) — stress on the first syllable, a short 'e', the 'ph' as /f/, and the final 'y' reduced to a schwa — after Zephyrus, the Greek god of the west wind. Non-native devs routinely misread the Greek-via-Latin spelling as ZEE-fire, zeh-FEER or ZEP-hire.

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. Pronounce is a community-maintained dictionary — every entry tagged with a confidence level and (where possible) a citable source.
