corollary的词源

英文词源

corollary: corollary: [14] Latin corolla was a ‘little crown or garland’, typically made from flowers (the word was a diminutive form of corōna ‘crown’, source of English crown). Hence a corollārium was ‘money paid for such a garland’, and by extension ‘gratuity’. Later it developed the meaning ‘deduction’, applied in geometry to a subsidiary proposition dependent on a previous proof, the sense in which it was first borrowed into English. (English acquired corolla itself in the 17th century.)
=> coronary, crown
corollary (n.): late 14c., from Late Latin corollarium "a deduction, consequence," from Latin corollarium, originally "money paid for a garland," hence "gift, gratuity, something extra;" and in logic, "a proposition proved from another that has been proved." From corolla "small garland," diminutive of corona "crown" (see crown (n.)).

来自corolla, 花冠。字面意思即买花要付钱，付钱买花。后用于逻辑术语，指推论。

这个单词逻辑学上常用，指前一个陈述所自然引发的后一个结论。字面意为“a little garland一个小花环”，词根本意是弯曲（因为花环可戴在头上或脖颈上）。逻辑含义大体为：买了花费较多的花篮后，店主因此情愿奉送一个较之花篮不值钱的花环。
