How it sounds

An unaspirated t, like the t in “stop”. Paiboon and some other systems write it dt to keep it apart from the aspirated ท and ถ.

One other letter has the same sound at the start of a syllable: ฏ to patak (mid).

Easy to mistake for ด do dek and ฏ to patak: compare them at a large size in the grid below.

Class and tone

Mid-class letters are the only ones that take all four tone marks. With no mark, a live syllable has the mid tone and a dead one the low tone; mai ek gives low, mai tho falling, mai tri high and mai chattawa rising.
