Oh really? What does that mean exactly?

Root Explanation

Dibasic → It is formed from "di-" (meaning two) and "basic" (from Greek "basis", meaning foundation or base). The word "dibasic" refers to a compound that has two basic groups or can react with two equivalents of an acid.

Memory Tip

Think of 'di-' meaning two, and 'basic' referring to a foundation — so dibasic describes something with two foundational parts.
