### What’s happening?

The answers to both quizzes are at the bottom, but you might have noticed that they follow a pattern!

English has borrowed a lot of words from other languages, especially those from Europe.

The ancient Greeks were very good at mathematics. Some ancient Greek textbooks, such as Euclid’s *Elements,* were so good they were studied for thousands of years. A lot of maths words are borrowed from ancient Greek, including ‘hexagon’, ‘arithmetic’ and ‘mathematics’.

The ancient Romans ruled over a large empire, which covered most of Europe, the Middle East and North Africa. Even after the fall of Rome, many people used the Roman language, Latin. Latin is still used in some Catholic masses, in the scientific names of species, and by lawyers. A lot of English words come from Latin – including the word ‘science’!

Octopuses and octopodes are both accepted ways of referring to more than one octopus.
