How this list was compiled: Own work: the lines under each name and the four sets were written for this site. Checked 2026-09-30 and again 2026-10-03. The 44 consonant letters, their order, each letter's name in the Royal Thai General System of Transcription, the meaning of the name word, the sound at the start and at the end of a syllable and the class of each letter: https://en.wikipedia.org/wiki/Thai_script. The same 44 letters with their name words in Thai, meanings and classes were compared with http://www.thai-language.com/ref/consonants, which writes the names in its own spelling; the classes agree for all 44 letters and the closing sound for the 33 letters where a closing sound is printed. For so so the two pages give different closing sounds, so the card prints none. Letters and their order were also compared with the Unicode character names list, https://www.unicode.org/Public/UCD/latest/ucd/NamesList.txt, whose spellings (pho phung, so rusi) are accepted as typed answers. The romanization, and what it leaves out: https://en.wikipedia.org/wiki/Royal_Thai_General_System_of_Transcription. On 2026-10-03 every card was compared again with the Wikipedia table, and each letter's place in the alphabet and its name word with the letter's own entry in English Wiktionary, https://en.wiktionary.org/wiki/ก (the same address pattern for each letter); the name words were read in their own Wiktionary entries, except นกฮูก, which has none. Three cards changed that day: do chada (a tall headdress or crown, as both sources describe it), tho montho (th or d at the start, as the table prints) and yo yak (usually part of the vowel at the end, as the table's note says).

How it works
Thai alphabet flash cards for the 44 consonant letters, from ก ko kai to ฮ ho nok huk. The back gives each letter's name in the Royal Thai General System, what the name word means and the sounds it writes.
Read the full guide
Names, sounds and three classes
Each Thai consonant is named with a word that goes with it: ก is ko kai, and kai means chicken. The back also gives the sound the letter makes at the start of a syllable and at the end, which often differ. Turn one card, then show one class (middle, high or low) or the look-alike letters under Show only, or open More options to type the names.
Print the Thai letters
Press the print button under the card for twelve letters to a sheet, with the names mirrored on the back. Print one sheet first to see that your printer draws the Thai letters.
Two letters, ฃ kho khuat and ฅ kho khon, have dropped out of writing. They keep their places in the alphabet.
The cards hold consonants only. Thai vowels are signs written above, below, before or after a consonant.
Questions and answers
How many letters are in the Thai alphabet?
There are 44 consonant letters, which between them write 21 consonant sounds. Vowels are written with separate signs placed around the consonants, so they are not counted among the 44.
What are the three classes of Thai consonants?
Middle, high and low. A letter's class helps decide the tone of its syllable, together with the length of the vowel and any tone mark. Nine letters are middle class, eleven high and twenty-four low.
Which romanization do the cards use?
The Royal Thai General System of Transcription (RTGS), the official system. It writes kh, th and ph for sounds made with a puff of air, and it marks neither tones nor vowel length. Other books spell the same names differently.
