ใต้

Under

Level 1

Use ใต้ (tâi) to describe something physically located underneath another object, or to refer to the Southern region of Thailand.

How It Works

1. Describe the Displayed Position
แมวอยู่ใต้โต๊ะ and รองเท้าอยู่ใต้เตียง place the cat under the table and the shoes under the bed. The requested construction is [Subject] + อยู่ + ใต้ + [Reference Object]. Here อยู่ supplies location, not a claim that a cat or shoes reside somewhere. The dictionary also gives เขาซ่อนเอกสารไว้ใต้โต๊ะเขียนหนังสือ, with ใต้ in an action sentence rather than immediately after อยู่.

2. Read the Regional Meaning
In เขาชอบไปเที่ยวภาคใต้, ภาคใต้ names the southern region. The dictionary separately records ใต้ as south or to the south, alongside its under/beneath senses. Choose the reading from the full expression.

3. Keep the Age Comparison Distinct
The age exercise requests อายุน้อยกว่า 18 ปี, less than 18 years old. Learn that comparison as a complete expression, rather than replacing an English under mechanically with ใต้. This is not a claim that ใต้ has only physical uses or that every quantity must use one fixed comparative word.

4. Read the Exact Spelling
ใต้ is written with ใ and Mai Tho above the mid-class ต, giving a falling tone in this spelling. Read the written vowel and mark together; no frequency or keyboard rule is implied.

Examples (4)

  1. แมวอยู่ใต้โต๊ะ

    The cat is under the table.

    Word by Word: cat / [is located] / under / table

    The cat is located under the table in this sentence.

  2. รองเท้าอยู่ใต้เตียง

    The shoes are under the bed.

    Word by Word: shoes / [are located] / under / bed

    The sentence locates the shoes under the bed.

  3. เรานั่งอยู่ใต้ต้นไม้

    We are sitting under the tree.

    Word by Word: we / sit / [are located] / under / tree

    The sentence places our sitting under the tree; shade is a possible setting, not an explicit separate word in the sentence.

  4. เขาชอบไปเที่ยวภาคใต้

    He likes to travel to the Southern region.

    Word by Word: he / like / go / travel / region / South

    Demonstrates ใต้ used as a geographical direction (South).

Common Mistakes

  • Omitting the verb 'yùu' (อยู่) when describing location.

    แมวใต้โต๊ะ
    แมวอยู่ใต้โต๊ะ

    This exercise requests the complete location construction แมวอยู่ใต้โต๊ะ with อยู่. แมวใต้โต๊ะ does not reproduce that requested construction; it may function as a noun phrase or a contextual fragment, so this is not a universal ban on omitting อยู่.

  • Using 'tâi' for numerical 'under' (e.g., under 18 years old).

    อายุใต้ 18 ปี
    อายุน้อยกว่า 18 ปี

    For this requested age comparison, reproduce อายุน้อยกว่า 18 ปี. The linked น้อยกว่า supplies less than. อายุใต้ 18 ปี does not reproduce the requested comparative expression; do not infer that the regional and other dictionary senses of ใต้ disappear.

Learn This First

To use 'ใต้' (under) effectively, you should first understand how to express location using 'อยู่' (to be at a place) and the basic word order of Thai sentences. This allows you to construct simple sentences describing where things are positioned relative to other objects.
