Phono-semantic compound (形聲 / 形声, đất): semantic 土(“earth”) + phonetic 得(đắc). The phonetic radical is based on the Central and Southern pronunciation of đất with the -k ending.[2]
^ Duc Du Huynh (18 June 2025), “An analytical study on the rationale and characteristics of Vietnamese Sinographic variant characters”, in Journal of Chinese Writing Systems, page 102:
There are differences in the variant characters used in different regions to express the same Vietnamese vocabulary, primarily attributed to the variation in Vietnamese dialects and the influence of language contact. The example 坦—𡐙 illustrates the regional differences in analyzing these variant characters. For instance, when expressing the meaning of land, texts from the northern region use 坦, while literature from the central region uses 𡐙.
