adverb / noun

yesterday

YES-ter-day/ˈjestərdeɪ/

The day before today.

The picnic was rainy yesterday, but today's calendar leaf shows sunshine.

Two adjacent calendar leaves, a curled previous leaf shows a rainy picnic and the current upright leaf shows bright sun; yesterday as preceding day, no text.
Etymology

The compound pairs a word already meaning “yesterday” with “day,” explicitly naming the day immediately before today. Other Germanic languages often use their equivalent of the first element alone.
