How to say "chemistry" in Japanese
Choosing the right word
- 化学かがくnounThe science of substances, elements, and their reactions — the academic subject or field of study. This is the word for chemistry class, a chemistry lab, or a degree in chemistry.
- 相性あいしょうnounThe figurative sense: the natural compatibility or rapport between people. When you say two people 'have good chemistry', 相性 is the natural word, not the science term.
Use 化学 for chemistry as a science or subject; use 相性 for 'chemistry' in the figurative sense of how well two people get along.
