For those trained in formal argument, the syllogism is a classical form of deduction. 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 through Greek to the 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."
