Origin and Evolution of penicillin

First Known Use: 1929 year

Language of Origin: Latin

Story behind the word: The word 'penicillin' originated from the Latin word 'Penicillium', which means 'brush' or 'paintbrush'. It was named after the mold that produces the antibiotic.

Evolution of the word: Initially used to refer to the mold itself, 'penicillin' later came to specifically denote the antibiotic derived from the mold. Over time, the word has become synonymous with a powerful antibiotic used to treat bacterial infections.
