darapti Logic.|dəˈræptaɪ|
A mnemonic term designating the first mood of the third figure of syllogisms, in which both premises are universal affirmatives (a, a), and the conclusion a particular affirmative (i).
The initial d indicates that the mood may be reduced to darii of the first figure; the p following the second vowel that there must be conversion per accidens of the minor premiss.
