U+0E10 "ฐ" Thai Character Tho Than Unicode Character

U+0E10 "ฐ" Thai Character Tho Than is the fortieth letter of the Thai alphabet and is classified as a high-class consonant, representative of the sound /tʰ/ as in the English "top" but with an accompanying aspirated release. Its name "Tho Than" derives from the Thai word "ฐาน" meaning "base" or "pedestal," reflecting its traditional mnemonic association with a supporting structure. Visually, the character is distinct for its tall, straight vertical stroke and a closed circular loop at the top, which sets it apart from other Thai consonants in written form. This letter appears in a limited number of native Thai words and is more commonly found in Pali and Sanskrit loanwords, where it often occupies the initial position in syllables. In the Thai numeral system, the character is also used to denote the number eight, a secondary function that underscores its cultural and linguistic significance beyond mere phonetics.
