  1. (intransitive, followed by that) To reach a conclusion by applying rules of logic to given premises.

Usage notes[edit | edit source]

For example, from the premises "all good people believe in the tooth fairy" and "Mary does not believe in the tooth fairy", we deduce the conclusion "Mary is not a good person". This particular form of deduction is called a syllogism. Note that in this case we reach a false conclusion by correct deduction from false premises.
