I heard that the water in the river is impurer than usual this season.

Synonyms & Antonyms

Root Explanation

Impurer → It is formed from "im-" (meaning not) and "pure" (from Latin "purus", meaning clean or untainted) and "-er" (meaning one who). The word "impurer" means one who is not clean or untainted, indicating a lesser degree of purity.

Memory Tip

Think of 'not clean' ('im-') and 'pure' — that's why impurer means less pure or not clean.
