Root Explanation

Pyritous is derived from "pyrite" (from Greek "puritēs", meaning of fire or fiery) and the suffix "-ous" (meaning full of or possessing). The word describes something that is full of or resembling pyrite, which is known for its metallic luster and resemblance to gold, often associated with fire due to its spark-producing properties when struck.

Memory Tip

Think of 'pyrite' which is known for its fiery spark and the suffix '-ous' meaning full of. This helps you remember that 'pyritous' refers to something that is full of the qualities of pyrite.
