Name

The name “Celarent” is a mnemonic term, in which the vowels (e-a-e) indicate that all three statements are universal quantifications: the first premise is a negative (type “e”), the second affirmative (type “a”) and the conclusion is again a negative statement (type “e”).

For more information on this naming scheme, and on syllogisms in general, see the article on syllogisms in the glossary.
