- corollary
[corollary 词源字典] - 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.)

- 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.)).
