What ๔ means
It stands for four.
Thai number strings use ordinary place value: ๑๔ is fourteen; ๔๐ is forty.
Thai writing has deeper regional roots: Pallava-style writing, an early South Indian script, appears in inscriptions in present-day Thailand in the 9th–11th Buddhist centuries (Thailand's Buddhist Era calendar). Old Thai writing is attested in Sukhothai in the 13th century CE.
In 2026, Arabic digits are the everyday digital default; ๔ gives writing a deliberately Thai-script, more formal register.
