Root Explanation

Amphoteric → It is formed from "ampho-" (from Greek "amphoteros", meaning both or on both sides) and "-teric" (from Greek "terikos", relating to). The word describes a substance that can act as both an acid and a base, thus relating to both sides of the chemical spectrum.

Memory Tip

Think of 'both sides' ('ampho-') when remembering that 'amphoteric' refers to a substance that can behave like both an acid and a base.
