CON-CEN'TER, v.i. [Fr. concentrer; It. concentrare; Sp. and Port. concentrar; con and L. centrum, a center; Gr. κεντρον, a goad, a sharp point, a center; κεντεω, to prick or goad. The primary sense is a point.]

To come to a point, or to meet in a common center; used of converging lines, or other things that meet in a point. All these are like so many lines drawn from several objects, that in some way relate to him, and concenter in him. – Hale.
