Root Explanation

Halogenation → It is formed from "halo-" (from Greek "halos", meaning salt) and "gen" (from Greek "genes", meaning born of or produced by) and the suffix "-ation" (indicating a process). The word refers to the process of introducing halogens into a compound, essentially producing a compound that contains halogen elements.

Memory Tip

Think of 'salt' ('halo-') being 'produced' ('gen') in a process ('-ation') — that's what halogenation means, the process of adding halogens to a compound.
