Why
Question · Eridian chord · 왜
In the Eridian chord language from Andy Weir's Project Hail Mary, the concept why (왜) is spoken as a 3-note chord rather than spelled out letter by letter. Eridians communicate by sounding musical notes simultaneously, so “why” is heard as D4, F4, A♯4, played with a rising pitch, over 0.5 seconds.

How “why” sounds in Eridian
“why” is built from 3 notes — D4, F4, A♯4 (293.66, 349.23, 466.16 Hz) — sounded for 0.5 seconds. The chord rises in pitch as it plays — a contour this translator reserves for questions. It belongs to the question category, which collects question words and conversational responses. In English it covers why; in Korean it maps to 왜.
