Translation guide
The English word 'synthetic' refers to something artificial, man-made, or produced by chemical synthesis. In Japanese, the most common equivalent is 合成 (gōsei) for chemical or material contexts, while 人造 (jinzō) is used for man-made objects. For abstract uses like 'synthetic judgment' or 'synthetic language', specific terms apply. This guide covers practical meanings for learners.
