KK: /ˈsmɛktaɪt/
A type of clay mineral that has a layered structure and can absorb water and expand.
Smectite is often used in drilling fluids due to its ability to swell and retain water.
Smectite is derived from the Greek word "smektos" (meaning to be able to be smeared or spread), which refers to the clay's ability to absorb water and swell. The suffix "-ite" is commonly used in mineralogy to denote minerals or rocks. Thus, smectite refers to a type of clay mineral that can be smeared or spread due to its unique properties.
Think of the Greek word for 'smeared' or 'spread' to remember that smectite is a clay mineral known for its ability to absorb water and expand.
