Root Explanation

Protonate → It is formed from "proton" (from Greek "protos", meaning first) and "-ate" (a suffix used in chemistry to indicate a process). The word "protonate" refers to the process of adding a proton to a molecule or ion.

Memory Tip

Think of 'proton' as the 'first' particle in an atom, and '-ate' indicating a process. So, protonate means to add a proton to something.
