Chinese grammar - Using 哪 (nǎ) for 'which' or 'which one'

Using 哪 (nǎ) for 'which' or 'which one'

The question word 哪 (nǎ) is used to ask about choice or selection among multiple options.

— It functions similarly to 'which?' in English.

It should be used with the appropriate counter (measure word) when referring to a choice among nouns.

When asking the general 'which one?' we use 哪一个？ (nǎ yī gè?).

Examples:
	你喜欢哪本书？ nǐ xǐhuān nǎ běn shū? Which book do you like? 哪 (nǎ) means 'which'
	他住哪个房间？ tā zhù nǎ gè fángjiān? Which room does he live in?
