ท ทหาร

01The sound it makes

6 of the 44 letters open a syllable with th, so the sound on its own will never tell you which one you are looking at. 18 letters close one with -t, and ท is among them.

02The tone it decides

Low class takes the same two marks high class does and means something different by them: on ท, ◌่ gives falling rather than low and ◌้ gives highrather than falling. A dead syllable then turns on the vowel’s length.

03Where it sits in a word

The same letter is two sounds: ท is th at the front of a syllable and -t at the back. Of the 4,271 words in this app it opens 192, sits inside 591 and closes 25.

Position here is orthographic — where the letter is written, not where it is said. The five leading vowels เ แ โ ใ ไ are skipped when deciding what comes first, so ไก่ counts as a word that starts with ก.

04Text it turns up in

A word list is a specimen jar. 48 of the 221 sentences and phrases in this app are written with ท somewhere in them — here are 4, shortest first, with every ท lit.

05The class it belongs to

ท is one of 24 low-class consonants. That membership is the single fact the ladder in 02 is built on — change the class and every tone in it changes. Here they all are, with ท lit among them.
