一昨昨日
さきおととい
- middle-high (nakadaka): falls after mora 5
How to read it: a line over a kana means the voice is high there, and ↓ marks where it drops. A kana with no line is low. With no ↓ the pitch stays high to the end and does not drop even on a following particle (が, は).
two days before yesterday, three days ago
Sakiototoi is 先 (saki, “previous”) plus 一昨日 (ototoi, “day before yesterday”); the kanji spelling is jukujikun.
