When is one เอ็ด instead of หนึ่ง in Thai?

When it is the last digit of a number bigger than ten. Eleven is สิบเอ็ด and twenty-one is ยี่สิบเอ็ด, but one on its own is หนึ่ง.

Why is twenty ยี่สิบ and not สองสิบ?

Twenty is irregular in Thai and keeps an older word for two, ยี่. Every other multiple of ten is regular.

Tool

Thai numerals still turn up on menus, temple entry signs and dual pricing. Type a figure to get the numerals, the words, and how to say them.

Number

Try 11 and 21 to see เอ็ด et, or 20 to see ยี่สิบ yii sip.

In Thai

Counting in Thai is regular. Everything around counting is not, so here is where you still have to do the work.

Two coffees is กาแฟสองแก้ว kaafae song kaeo, and that last word changes with the thing you are counting. Classifiers are here.

Whole numbers only. Dates, years and telling the time each follow their own pattern, and the course teaches them separately.

A figure here is just a figure. For baht rates, use the currency converter.
