Root Explanation

Irreducible → It is formed from "in-" (meaning not), "reducere" (meaning to lead back or bring back), and "-ible" (meaning capable of). The word "irreducible" means not capable of being brought back or simplified further.

Memory Tip

Think of something that cannot be 'brought back' or simplified — 'in-' means not, 'reducere' means to lead back, and '-ible' means capable. This helps you remember that 'irreducible' refers to something that cannot be simplified.
