From...To (从...到)

从...到 is a paired preposition structure meaning "from...to." It works for both time and place. 从 (cóng) marks the starting point, and 到 (dào) marks the ending point.

For time: "从星期一到星期五" (cóng xīngqī yī dào xīngqī wǔ) — "from Monday to Friday." For place: "从北京到上海" (cóng Běijīng dào Shànghǎi) — "from Beijing to Shanghai." The structure is the same regardless of whether you are talking about time, space, or even abstract ranges.

In a full sentence, the 从...到 phrase typically comes before the main verb, acting as a prepositional phrase that sets the context. For example: "我从家到学校要二十分钟" — "It takes me twenty minutes from home to school." Or: "从早上到晚上，他都在工作" — "From morning to evening, he is always working."

从 and 到 can each be used independently as well. 从 alone means "from": "我从美国来" (I come from America). 到 alone means "to" or "arrive at": "我到学校了" (I arrived at school). But when paired together, they form the "from...to" range.
