ม ม้า

01The sound it makes

ม is the only one of the 44 letters that opens a syllable with m. And it is the only one that closes a syllable with -m.

02The tone it decides

Low class takes the same two marks high class does and means something different by them: on ม, ◌่ 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: ม is m at the front of a syllable and -m at the back. Of the 4,271 words in this app it opens 132, sits inside 815 and closes 300.

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. 107 of the 221 sentences and phrases in this app are written with ม somewhere in them — here are 4, shortest first, with every ม lit.

05The class it belongs to

ม 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 ม lit among them.
