The kanji 坪 is a 形声文字 (keisei moji), which means it combines a semantic component (a part indicating meaning) and a phonetic component (a part indicating pronunciation). The semantic component is thought to relate to the concept of a flat surface or a measured area. The phonetic component, which originally related to a measurement of grains, evolved to represent the sound *hei*. Over time, the character became associated with the specific unit of area, *tsubo*.
