Did you know that cacti have tiny structures called spinules?

Really? I thought they just had thorns.

Root Explanation

Spinule → It is formed from "spina" (meaning thorn or spine) and the diminutive suffix "-ule" (meaning small). The word "spinule" refers to a small thorn or spine, often used in biological contexts to describe tiny, spine-like structures.

Memory Tip

Think of a 'thorn' ('spina') that is 'small' ('-ule') — that's why a spinule is a tiny thorn or spine.
