also: わっぷ
noun
tally; split receipt; proof of transaction
Historical term for a wooden or paper tally split in two, each party keeping one half as proof of a transaction or agreement. Rare in modern daily life but appears in historical contexts.
江戸時代には、金銭の貸し借りに割符が使われた。
In the Edo period, split tallies were used for lending and borrowing money.
割符を合わせて、取引の証拠とした。
They matched the two halves of the tally as proof of the transaction.
Alternate spelling with okurigana; less common but still used.
Compound of 割り (wari, 'splitting') and 符 (fu, 'tally' or 'token'). The reading わっぷ is a historical sound shift from わりふ.
