The ability of a substance to absorb moisture from the air.
The hygroscopicity of the material makes it ideal for use in humid environments.
Hygroscopicity → It is formed from "hygro-" (from Greek "hygros", meaning wet or moist) and "scopic" (from Greek "skopein", meaning to look or examine) combined with the suffix "-ity" (meaning the state or condition of). The word describes the condition of a substance that has the ability to absorb moisture from the air.
Think of 'moisture' ('hygro-') being 'examined' or 'looked at' ('scopic') — that's why hygroscopicity refers to the ability to absorb moisture.
