อาทิ

Explanation

อาทิ signals that the items that follow are representative examples rather than a complete list. Its basic pattern is อาทิ followed by a list of nouns or noun phrases. It has a formal, written feel and is common in reports, news, public notices, and presentations. In everyday conversation, เช่น is usually more natural. The word historically also has the sense of “first” or “initial,” but that use is now mainly found in compounds and specialized or elevated writing. Most learners only need its example-introducing use.

Usage

It is used when listing representative services, activities, places, causes, or other members of a larger category. It is especially suitable for prepared or formal language such as reports, news, public information, and promotional copy.

Caution

อาทิ normally comes before the examples. To close a list with “and so on,” เป็นต้น is more natural. In casual speech, เช่น is generally preferred, especially when giving a single example. The combined form อาทิเช่น is also used, although either อาทิ or เช่น alone is often sufficient in concise writing.

1 such as synonyms

• เช่น

  chên such as

  เช่น also means “such as” or “for example” and is the more versatile, everyday choice. อาทิ sounds more formal and is especially common when listing examples in reports, news, and prepared explanations.

• เป็นต้น

  เป็นต้น normally comes after a list and closes it with the sense of “and so on.” In contrast, อาทิ usually appears before the examples it introduces.

• เป็นต้นว่า

  เป็นต้นว่า is another relatively formal expression meaning “for example.” อาทิ is more compact and works especially well before a list of nouns or noun phrases.
