[edit] Verb

to deduce (third-person singular simple present deduces, present participle deducing, simple past and past participle deduced)

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

[edit] Usage notes

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.
