Meaning & readings
yesterday, previous
Origin
This character combines the sun radical (日) on the left, which marks the character as relating to time or days, with a sound component (乍) on the right that hints at the pronunciation. The sun radical makes sense for a time-related word since the sun's daily cycle marks the passage of days. By pairing this meaning element with the sound hint, the character came to represent a specific time concept—yesterday, or the day that has already passed.
