KJV Dictionary Definition: soder
SOD'ER, v.t. It has been taken for granted that this is a contracted word, from L. solido, and hence written solder. The fact may be doubted; but if true, the settled pronunciation seems to render it expedient to let the contracted orthography remain undisturbed. To unite and make solid, as metallic substances; to join separate things or parts of the same thing by a metallic substance in a state of fustion, which hardens in cooling, and renders the joint solid.
SOD'ER, n. Metallic cement; a metal or metallic composition used in uniting other metallic substances.
