Most
LSAT glossary · Law School Admission Test (LSAT)
Definition
An LSAT logical quantifier meaning "more than half." "Most students passed" means strictly greater than 50% passed. "Most" is weaker than "all" and stronger than "some," and unlike "all" it does not create a guaranteed conditional. The Overlap Principle is the key inference: if Most A are B AND Most A are C, then some A are both B and C — because two majorities of the same set must share at least one member. "Most A are B" entails "Some A are B" but never entails "All A are B."
Most in plain English
'Most' on the LSAT means strictly more than half — over 50%, full stop. It sits between 'some' (at least one) and 'all' (every single one): stronger than some, but weaker than all, and crucially it does NOT create an ironclad if-then rule the way 'all' does. Its signature move is the Overlap Principle: if most A are B AND most A are C, then at least one A must be both B and C — because two majorities of the same group can't dodge each other; they're forced to share a member (picture two groups each grabbing more than half the same class — they must overlap on at least one kid). Note 'most A are B' guarantees 'some A are B,' but never 'all.'
