KK: /dɪˈfɛrənʃə/
A quality or feature that makes one thing different from another, often used to describe what sets apart one species from others in biology.
The differentia of the species is its unique coloration and size.
Differentia → It is formed from "differre" (meaning to carry apart) and the suffix "-entia" (indicating a state or condition). The word "differentia" refers to the state of being different or the quality that distinguishes one thing from another.
Think of 'carrying apart' ('differre') to remember that 'differentia' means the quality that makes something distinct.
