Ordinal numbers (ที่)

Making Numbers Ordinal

In English, we memorize special words to turn counting numbers into sequence numbers, like changing "one" to "first" or "two" to "second." In Thai, it is much simpler. You just place the word ที่ immediately before any normal number.

When talking about a specific sequential item in a sentence, the order is always Noun + ที่ + Number:

ชั้น floorชั้นที่สองsecond floor
อันดับ rankอันดับที่สามthird place
รางวัล prizeรางวัลที่หนึ่งfirst prize

Floors of a Building

To talk about floors in a building, state the word for floor (ชั้น), followed immediately by your ordinal number.

If you are heading to a different floor, you will likely need the verb to go up (ขึ้น) and an elevator (ลิฟต์).

Rankings and Prizes

Ordinal numbers are also essential when a team (ทีม) plays in a competition (การแข่งขัน). You will use them to describe exactly what rank (อันดับ) or prize (รางวัล) they received (ได้).

Winning first place usually means you also get a gold (ทอง) medal (เหรียญ).
