词源

词源 1

The adjective is first attested in 1825, the verb in 1658. Borrowed from Latin decussātus, perfect passive participle of decussō (“to divide crosswise, arrange crosswise or mark with a cross”) (see -ate (adjective-forming suffix) and -ate (verb-forming suffix)), from decussis (“a coin worth ten asses; a cross sign (from the cross shape of the Roman numeral for ten carved on the coins)”), from decem (“ten”) + as (“a Roman coin”).
