biology (English)
Where does "biology" come from?
The word "biology" originates from the combination of two Ancient Greek roots: "bíos," meaning life, and "logía," meaning the branch of study. This term entered New Latin as "biologia" before being adopted into English in the late 18th century to describe the scientific study of living organisms. Its evolution reflects a linguistic bridge from Proto-Indo-European roots for living to the modern, structured life sciences we define today.
