Talk:deduce

Etymology
Is "deduction" related to "deduce" or "deduct" - or both? &mdash; 141.168.28.158 14:59, 13 Aug 2004 (UTC)


 * Both. They all come ultimately from the Latin verb deducere "to lead/bring out (or away)".  The past participle of the verb, deductus, gives us "deduct"—most verbs borrowed from Latin are borrowed from the participle form.   From that verb comes the derivative form deductio "an act of deduction/deducing". —Muke Tever 22:31, 13 Aug 2004 (UTC)

Transitivity
The single definition is tagged "intransitive, followed by that". I would prefer to see it marked simply transitive.

It seems arguably most correct to say that is transitive and idiomatically followed by a subordinate clause beginning with the word "that". I certainly have seen it used w/o "that"; I will keep my eyes open for a credible reference. The usage of the word, "deduce" bears some similarity to "see" or "say" as I have inadvertently used here.

Usage note on corollaries

 * It is the nature of corollaries that they are usually deducible.

Why is that a usage note here? It seems to be more apt to mention it at corollary. —DIV (49.179.37.152 11:37, 30 March 2024 (UTC))
