What does Yi mean in ancient poetry?

"Yi" is an auxiliary word at the end of the sentence in ancient Chinese, which is used to express the tone of affirmation or doubt, similar to "le" and "ne" in modern Chinese. "One" is widely used in almost all types of sentences, such as expressing facts, asking for information, expressing sighs and so on. In ancient poetry, "one" also appears frequently, and its meaning is different because of different tone and context.

Xin Qiji, a poet in Song Dynasty, used the word "one" extensively in Yuan Yu Xia, expressing the poet's yearning for his old friend on the night of Yuan Dynasty. In that sentence, "I expect, I think, I am green, I am in my heart." In Chinese, "Yi" means mood, which makes the whole poem more intense. This application enhances the lyrical effect and makes readers better feel the poet's inner entanglement and yearning.

With the evolution of Chinese, "one" gradually withdrew from the common vocabulary of modern Chinese and no longer appeared in various sentences like ancient Chinese. However, in some literary works, ancient poems and traditional culture, Yi still occupies an important position. Mastering the context and meaning of "Yi" is of self-evident significance for understanding ancient Chinese and appreciating China traditional culture. In today's Chinese, "one" is mainly used in oral communication, which can express confirmation, approval and inquiry, such as "yes" and "going out".
