Root Explanation

Haustellum is derived from the Latin root "haurire" (meaning to draw or to drink) and the diminutive suffix "-ellum" (indicating a small size). Thus, "haustellum" refers to a small structure used for drawing or sucking, particularly in the context of certain insects' mouthparts.

Memory Tip

Think of 'drawing' ('haurire') something small ('-ellum') — that's why a haustellum is a small structure that draws in fluids.
