Usage of 哪个
“哪个” is a common interrogative pronoun used to ask about a specific person or thing among a known set. It combines “哪” (which) and the general measure word “个” to refer to 'which one'.
Common contexts
It is frequently used in everyday questions about preferences, choices, or identification, such as colors, people, or objects. For example, "你喜欢哪个颜色？" asks which color someone prefers.
Collocations and patterns
- 哪个 + noun: to ask which specific item or person
- 你想买哪个？: a common phrase to ask 'which one do you want to buy?'
Notes
“哪个” is neutral and polite, suitable for both formal and informal contexts. It differs from “哪儿” (where) and “什么” (what) by focusing on selection among options. Avoid confusing it with “哪” alone, which can be less specific without a measure word.
