cation

Etymology

Borrowed from Ancient Greek κᾰτῐόν (kătĭón), neuter present participle of κᾰ́τειμῐ (kắteimĭ, “to go down, come down”), from κᾰτᾰ- (kătă-, “downwards, down, cata-”) +‎ εἶμῐ (eîmĭ, “to go, come”). Coined by English polymath William Whewell in 1834 for Michael Faraday, who introduced it later that year. By surface analysis, cat(a)- +‎ ion.
