Root Explanation

Porous → It is formed from "porus" (from Latin, meaning a passage or pore) and the suffix "-ous" (meaning full of). The word "porous" describes a material that is full of tiny passages or pores, allowing liquids or gases to pass through.

Memory Tip

Think of a material that is 'full of passages' — 'porus' means a pore or passage, and '-ous' indicates it is full of them. This helps you remember that porous means something that can allow things to pass through.
