syllogism
noun
Did you know?
For those trained in formal argument, the syllogism is a classical form of deduction, specifically an argument consisting of a major and a minor premise and a conclusion. One example is the inference that "kindness is praiseworthy" from the premises "every virtue is praiseworthy" and "kindness is a virtue." Syllogism came to English through Anglo-French from Latin syllogismus, which in turn can be traced back to the Greek verb syllogizesthai, meaning "to infer." In Greek logizesthai means "to calculate" and derives from logos, meaning "word" or "reckoning." Syl- comes from syn-, meaning "with" or "together."
