อันไหน

Explanation

อันไหน consists of อัน, a general classifier or pronoun for things, and ไหน, “which.” Its basic image is “which one.” It can stand without a noun when the objects are visible or the available choices are already understood. Common answers include อันนี้ (“this one”) and อันนั้น (“that one”). The fixed pattern อันไหนก็ได้ means “any one” or “whichever one is fine.” This free-choice meaning comes from the addition of ก็ได้ rather than from a separate meaning of อันไหน itself. When the type of object is specified, Thai often uses its usual classifier, as in หนังสือเล่มไหน (“which book”) or รถคันไหน (“which car”).

Usage

It is frequently used when choosing products, comparing menu items or pictures, identifying belongings, or discussing any visible or previously mentioned set of options. It works with two choices as well as larger sets.

Caution

It normally refers to things. Use คนไหน for “which person.” When naming the object, Thai generally uses the order noun + classifier + ไหน, as in หนังสือเล่มไหน (“which book”).
