Your hand reaches for the chalkboard at the end of class to wipe away every last trace of today's lesson. You press your palm flat and drag it across, erasing line after line. By the end, the board is perfectly blank—as if nothing was ever written there.
Additional thoughts
Picture the satisfying sweep of a hand clearing a dusty chalkboard at the final bell. The end of class is the ritual moment for wiping away. The completeness of the erasure matches the kanji's sense of total obliteration.
