How to use 合成
合成 is common in science, technology and media, for things made by combining parts, such as chemicals, sounds or images. It often appears before a noun to mean synthetic or composite, as in 合成纤维 (héchéng xiānwéi, synthetic fiber). Example: 这张照片是合成的。(Zhè zhāng zhàopiàn shì héchéng de.) This photo is a composite.
合 (hé) means to join or put together, and 成 (chéng) means to become or complete. Put parts together until they become one new thing, and you have 合成 (héchéng), to synthesize or compose.
Common mistake: Learners often use 合成 where 组成 (zǔchéng) fits better. 组成 means members or parts make up a whole, as in 由五个人组成 (made up of five people), while 合成 suggests parts are blended into something new. Also keep the second syllable in the second tone: héchéng, not héchèng.
