An LSAT logical quantifier meaning "at least one; possibly all." "Some A are B" is true whenever the overlap between A and B contains one or more members — even if every A is B. Key inference rules: "All A are B" entails "Some A are B," and "Most A are B" entails "Some A are B," but "Some A are B" does not entail "Most" or "All." "No A are B" is the direct negation of "Some A are B."
