In Thai, prepositions are fixed position markers that reveal how Thai culture maps the world.
Understanding left in Thai and right in Thai isn’t just about directions. It’s about seeing how Thai connects space to geography (north/south), the human body (face/back), and surfaces vs. interiors.

Let’s map the positions:
นกอยู่เหนือต้นไม้(Nók yùu nǔea dtôn-mái)
The bird is above the tree.
(Hèt yùu dtâai dtôn-mái)
The mushroom is under the tree.
แมวอยู่บนต้นไม้(Maaeo yùu bon dtôn-mái)
The cat is on the tree.
(Grà-râawk yùu nai dtôn-mái)
The squirrel is in the tree.
(Mǎa yùu khâang sáai dtôn-mái)
The dog is on the left side of the tree.
(Dàawk-bua yùu khâang khwǎa dtôn-mái)
The lotus is on the right side of the tree.
Grà-dtàai yùu khâang-nâa dtôn-mái
The rabbit is in front of the tree.
แมวสีแดง อยู่ ข้างหลัง ต้นไม้Maaeo sǐi-daeng yùu khâang-lǎng dtôn-mái
The red cat is behind the tree.
Thai prepositions aren’t arbitrary—they connect to geography, the body, and physical surfaces.
เหนือ (nǔea) | Above / North
In the Thai mental map, “above” is the same word for “North.” When you go to Chiang Mai, you go “up North.”
ใต้ (dtâai) | Under / South
“Below” is the same word for “South.” Going to Phuket or Hua Hin? You’re going “down South” (ลงใต้).
ข้างหน้า (khâang-nâa) | In front of / Front side
Thai uses the word for your “face” to describe space in front of an object. What you face = what is in front.
ข้างหลัง (khâang-lǎng) | Behind / Back side
Thai uses the word for your “back” to describe space behind an object. Your back = what’s behind you.

บน (bon) | On
Strictly for being on top of a surface. The cat sits on the branch (touching it).
ใน (nai) | In
Refers to space inside. The squirrel hides in the tree trunk (enclosed).
ข้าง (khâang) | Side

You start with this word when talking about left or right:
ข้างซ้าย (khâang sáai) = Left side

ข้างขวา (khâang khwǎa) = Right side
