How to pronounce crate

crate is most commonly pronounced "krayt" (/kreɪt/). This is the widely-used reading among engineers, though edge cases exist.

Rust's unit of compilation / the package you publish to crates.io. Pronounced exactly like the wooden box "crate": KRAYT, one syllable, rhymes with "great" and "plate". Not "krah-tay" or "crayt-ee". (Asked by a non-native speaker in Discussion #34.)

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.
