bottom of a box
Rare literary term for the bottom of a box or container. In modern Japanese, 箱の底 (はこのそこ) is the usual expression.
In old documents, the expression 'hide at the bottom of a box' can be found.
Literary kanji compound; 筐 means 'box' and 底 means 'bottom'. Rarely used in modern Japanese.
Variant kanji form using 篋 (also meaning 'box'). Equally rare.
Compound of 筐 (box) and 底 (bottom). The exact historical derivation is uncertain; it is a literary Sino-Japanese word.
