1.
double line, two parallel lines drawn through text
Two parallel lines drawn through text on a document to indicate a correction or deletion. The standard method for crossing out errors on official Japanese documents.
Components: 二重 (double) + 線 (line).
On official documents in Japan, correction fluid (修正液) or erasers are not accepted for corrections. Instead, the proper method is to draw 二重線 through the error and stamp a 訂正印 (correction seal).
The 二重線 is drawn with a ruler for neatness. The original text should remain legible beneath the lines — the point is to show what was corrected, not to hide it.
