Definition
Chalky describes something that resembles chalk, whether in texture, appearance, or taste. It often refers to a dry, powdery feel, like when you touch a chalkboard. A chalky color is usually a pale, matte white, like actual chalk. Taste-wise, 'chalky' implies a dry, somewhat unpleasant sensation in the mouth. Think of certain medicines that leave a chalky residue. Chalky things are generally absorbent and lack a smooth or glossy surface.
