writing tablet; tablet
Refers to a flat surface used for writing, such as a slate or a digital tablet. The term is relatively uncommon in modern Japanese; more specific words like タブレット or 石板 are often used depending on context.
Ancient writing tablets were excavated from the ruins.
Compound of 書字 (shoji, 'writing characters') and 板 (ban, 'board, plate'). The exact historical origin is uncertain, but it follows a common pattern for naming writing surfaces.
