ส

thai character so sua

Thai Letter So Sua

ส, called so suea, sounds like s at the start of a Thai syllable and a t stop at its end. It is a letter, not an emoji. This Thai s belongs to the high consonant class—a spelling group that helps determine tone, not an instruction to pronounce it high.

What ส means

It is a consonant, not the word “tiger.” The tiger letter gets its name from เสือ, Thai for “tiger”: a memory aid for identifying ส.

Learn ส with the word it belongs to. Other Thai letters can share its sounds without being interchangeable; changing the letter can change the spelling or tone rules.

Where did ส come from?

Its form evolved within the Thai writing tradition. Early surviving Old Thai writing is associated with the 13th century. Tradition credits King Ram Khamhaeng with creating Thai script, but the dating and authenticity of the inscription bearing his name are debated.

Thai writing adapted inherited Indian-derived conventions to Thai sounds and tones. Consonant classes once reflected sound differences; they now help govern tone. A related writing tradition, Khom Thai, developed from Old Khmer in the 15th century for religious and ritual texts. It is a separate script tradition, not a font variant of ส.

ส carries no politeness or slang meaning by itself; read the Thai word around it.

The name's “tiger” is a memory aid, not a translation of ส.

ซ

Combination ideas

One ส ends a syllable as t and starts the next as s.

Questions people ask

Why does ส show as a box on some devices?

Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
