Science & Technology Vocabulary
Explore the vocabulary used for science and technology — computers, robotics and artificial intelligence, medicine, space, the environment, and academic research — for learners anywhere in the world.
One domain, several areas of vocabulary
Science and technology bring together several connected areas of vocabulary.
This section includes language for computers and devices, robotics and artificial intelligence, healthcare and medicine, space and astronomy, the environment and sustainability, and academic research and writing.
Science & Technology is a domain grouping, not a single vocabulary list. Each topic explores its vocabulary as a connected system, showing how words relate to and differ from one another, rather than as an alphabetical glossary — and each is written to stay useful wherever you happen to be, since devices, robots, AI systems, healthcare systems, and research conventions all vary from country to country and field to field.

These six topics explore different areas of Science & Technology vocabulary. They can be explored independently, in any order.
How these lessons work
Vocabulary becomes more useful when related words are learned together.
Each topic in this domain explores its vocabulary as a connected system rather than a list of isolated words. You’ll typically encounter a concept, the vocabulary connected to it, useful distinctions between similar words, natural word combinations, and realistic examples of the language in use — though the exact shape adapts to what each topic actually needs. Devices, robots, AI systems, healthcare systems, energy sources, and research conventions all vary between countries and fields, so each lesson focuses on the vocabulary itself rather than any one country’s or institution’s way of doing things.
