word
👉💬 zhe jiu shi shuo = this + exactly-is + to-say — literally this exactly is saying
Break it down: 这 (this) + 就是 (precisely is) + 说 (say/speak). It acts like a verbal equals sign: everything before it is the setup, everything after is the explanation. Think of it as saying that is to say or in other words.
这 — walk radical 辶 + speech 言
这 is the simplified form of 這. The traditional character combines the walk/movement radical 辶 with 言 (speech), originally meaning 'to meet' or 'to encounter on the way.' Over time it shifted to function as the demonstrative 'this,' likely through phonetic borrowing in vernacular Chinese.
就 — 京 (capital) + 尤 (especially)
Originally a compound suggesting going to a high place (京 depicts a tall building) to settle or accomplish something. Over time the meaning shifted from 'approach a high place' to 'go to,' then broadened to 'accomplish,' and finally to the modern grammatical senses 'then,' 'just,' or 'precisely.'
是 — sun 日 + 正 (correct/upright)
Originally a compound suggesting 'the sun 日 directly overhead'—straight, correct, true. From this concrete sense of 'right' or 'this very thing,' 是 came to mean 'this' as a demonstrative, and later the modern copula 'to be / is.' The 'correct' meaning survives in words like 是非 (right and wrong).
说 — speech radical 讠(言) + 兑
说 combines the speech radical 讠(言, 'words') with 兑, which acts as the phonetic component. The character originally meant 'to explain' or 'to speak,' and broadened to mean 'say' or 'talk.' The same graph is also read 'yuè' meaning 'pleased,' a sense later written 悦.
