Root Explanation

Diphtheroid → It is formed from "diphtheria" (from Greek "diphthera", meaning leather or hide) and the suffix "-oid" (meaning resembling or like). The word "diphtheroid" refers to something that resembles diphtheria, particularly in its symptoms or characteristics.

Memory Tip

Think of 'diphtheria' as a condition that has 'leather-like' symptoms, and '-oid' means resembling. This helps you remember that 'diphtheroid' refers to something that resembles diphtheria.
