Etymology

From Late Middle English deducen (“to demonstrate, prove, show; to argue, infer; to bring, lead; to turn (something) to a use; to deduct”), borrowed from Latin d?d?cere, the present active infinitive of d?d?c? (“to lead or bring out or away; to accompany, conduct, escort; (figuratively) to derive, discover, deduce”); from d?- (prefix meaning ‘from, away from’) + d?cere (the present active infinitive of d?c? (“to conduct, guide, lead; to draw, pull; to consider, regard, think”), ultimately from Proto-Indo-European *dewk- (“to lead; to draw, pull”)).

Verb

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

   Synonyms: conclude, infer

   Antonym: induce
2. (transitive) To examine, explain, or record (something) in an orderly manner.
3. (transitive, archaic) To obtain (something) from some source; to derive.
4. (intransitive, archaic) To be derived or obtained from some source.

Usage notes

• Regarding sense 1 (“to reach (a conclusion)”), for example, from the premises “all good people believe in the tooth fairy” and “Jimmy does not believe in the tooth fairy”, we deduce the conclusion “Jimmy 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 a false premise.
