U+1A7B "᩻" Tai Tham Sign Mai Sam is a diacritical mark used in the Tai Tham script, primarily to write Northern Thai, Tai Lue, and other related languages. This sign functions as a tone marker, specifically representing the third tone, known as "Mai Sam," which is crucial for distinguishing word meanings in tonal languages. It is placed above or near a consonant character to modify its pronunciation, and its design reflects the traditional calligraphic style of the Lanna script, where it resembles a small, curved loop or hook.
