This term describes a type of crystal structure that has three axes of different lengths, where two of the axes meet at an angle that is not a right angle, and the third axis is at a right angle to one of the other two.
The mineral exhibits a monoclinic crystal system, which is evident in its unique shape.
Monoclinic → It is formed from "mono-" (meaning one) and "klinos" (from Greek, meaning slope or incline). The term describes a crystal system characterized by one axis of symmetry, hence the name monoclinic, indicating a single slope or incline.
Think of 'mono-' meaning one, and 'klinos' referring to a slope — this helps you remember that monoclinic describes a crystal system with one slope.
