1866 A. Cayley in Q. Jrnl. Pure & Appl. Math. 7 213 The stationary ineunt, or cusp, considered as..a particular case of the double ineunt, is a spinode; to render this notation symmetrical, we require certain new terms, say link, as the correlative to node, and flex as the correlative to cusp... The ordinary singularities of a plane curve would thus be the node, the cusp, the link, and the flex.
