The quality or condition of being able to hold or retain stains, often used in the context of materials or biological cells.
The stainability of the fabric determines how well it can resist discoloration from spills.
Stainability is formed from "stain" (from Old French *esteindre*, meaning to extinguish or to stain) and the suffix "-ability" (meaning the quality of being able to). The word refers to the quality of being able to be stained or the capacity to hold a stain.
Think of the word 'stain' which means to mark or discolor something, and '-ability' which indicates the quality of being able to. This helps you remember that 'stainability' refers to the quality of being able to be stained.
