文法句型

noun-stem + -cidal → adjective

用法筆記

The -cidal form is an adjective-forming suffix. Its noun counterpart is -cide. For example, a bactericidal spray (adjective) kills germs, while the spray itself is a bactericide (noun). These two forms are frequently confused by English learners.

常見錯誤

❌The farmer bought an insecticidal.
✅The farmer bought an insecticide.
💡-cidal forms adjectives, not nouns; use -cide for the noun.
❌This chemical is cidal.
✅This chemical is bactericidal.
💡-cidal cannot stand alone; it must attach to a base noun that names what is killed.
