Something that cannot be crushed or broken down easily.
The uncrushable material was used in the construction of the building to ensure its durability.
Uncrushable → It is formed from "un-" (meaning not) and "crush" (from Old French *crushier*, meaning to press or squeeze) and "-able" (meaning capable of). The word "uncrushable" means not capable of being pressed or squeezed, indicating something that cannot be crushed.
Think of 'not' ('un-') being able to 'press' ('crush') something, which helps you remember that 'uncrushable' means it cannot be crushed.
