Thai letter so rue-si (ษ)

Class high Initial s Final t
ษ so rue-si

Remember it

A hermit's staff - mostly in Sanskrit loanwords.

Thai children learn the letter by its full name, ษ ฤๅษี so rue-si, picture and all. Say the whole thing and the shape comes with it.

What its class does to the tone

High class cannot take mai tri or mai chattawa, and an unmarked live syllable comes out rising rather than mid. These three lines cover most of what you will meet, and they hold for ษ exactly as they do for every other high-class letter.

live syllable, no mark rising tone ขา khǎa Leg
with mai ek low tone ไข่ khài Egg
with mai tho falling tone ข้าว khâo Rice

The examples are whichever high-class word shows the rule most clearly. The full grid for all three classes is here.

Letters that sound the same

4 letters, one sound. Which one a word uses is spelling history rather than pronunciation, so these are learned as part of the word.

Easy to mix up with

Each pair differs by one stroke, and each mistake changes the word.

ษบ

ษศ
