phylum (English)
Where does "phylum" come from?
The word phylum traces back to the Proto-Indo-European root meaning 'to grow or become,' which also gave rise to the Ancient Greek word for a tribe or race of people. Scientists later borrowed this concept into Latin to categorize groups of organisms that share a common structural plan. Today, the term is used in biology and linguistics to describe broad families of related species or languages.
