Most nonbreakable refers to something that is almost impossible to break or damage. Its antonyms include words such as fragile, delicate, brittle, vulnerable, breakable, and weak. These words describe items or materials that can easily shatter, crack, or be damaged even with minor pressure or impact. While most nonbreakable implies robustness, durability, and resilience, its antonyms, on the other hand, suggest that the item or material is easily damaged or destroyed. Products such as glass, ceramics, or fine china are often considered to be fragile or delicate, while materials such as plastic, metal, or concrete are known for their strength and durability.
