1. Meaning and Usage
The structure "賣 + [動詞]" describes the act of offering a particular action, skill, quality, or even oneself for sale, or to exert/display a certain quality or action for a specific purpose. It implies that the action or quality itself is the commodity or the thing being emphasized. Unlike simply "selling an item" (e.g., 賣書 - sell books), where the verb is implied from the noun, here the verb directly specifies what is being sold or how one is behaving.

3. Essential HSK Tips & Common Mistakes
- Distinguish from "selling a noun": A common mistake is to confuse "賣 + [動詞]" with simply selling an object. For example, 賣書 means "to sell books," where "book" is a noun. In "賣唱," "唱" (sing) is a verb, and it's the act of singing that is being offered for money. The structure focuses on the action or quality itself as the commodity or the thing being exerted/displayed.
- Fixed Expressions: Many phrases using "賣 + [動詞]" are fixed, idiomatic expressions (e.g., 賣力, 賣乖, 賣弄). You cannot simply combine any verb with 賣 and expect a grammatically correct or natural-sounding phrase in this specific structure. Learn these as individual vocabulary items.
- HSK Relevance: Phrases like 賣力 (to exert oneself fully), 賣弄 (to show off), 賣唱 (to perform singing for money), and 賣藝 (to perform skills for money) are commonly encountered in HSK materials, especially at intermediate and advanced levels. Pay attention to their specific connotations.
- Connotation: Be aware that some expressions, particularly those involving selling oneself or one's body (like 賣身, 賣笑), carry strong negative or historical connotations. Use them with caution and only when appropriate to the context.
錯誤 (Incorrect): 他想賣跑。 Tā xiǎng mài pǎo. (Intended: He wants to sell running/cars that run)
正確 (Correct, to express similar idea differently): 他想賣跑車。 Tā xiǎng mài pǎochē. He wants to sell sports cars. (Here 跑 is part of the noun 跑車, not a verb sold separately.)
錯誤 (Incorrect): 她喜歡賣吃。 Tā xǐhuān mài chī. (Intended: She likes to sell food)
正確 (Correct): 她喜歡賣吃的。 Tā xǐhuān mài chī de. She likes to sell food (lit. "things to eat"). (Here, 吃的 refers to edible items, not the act of eating itself as a commodity.)
