・On-yomi (音読み): *hei* (へい) ・Kun-yomi (訓読み): *tsubo* (つぼ)

⚫︎一坪の土地 Translation: One *tsubo* of land ⚫︎家は100坪ある Translation: The house is 100 *tsubo* (in area). ⚫︎部屋の広さは何坪ですか？ Translation: How many *tsubo* is the size of the room?

The kanji 坪 is a phono-semantic compound (形声文字, *keisei moji*). The phonetic component is the right-hand side, *平* (hei), which suggests the sound. The left-hand side suggests that the meaning relates to the flat surface of a field. Therefore, 坪 originally represented a flat surface, such as land that is measured using square areas. Over time, it became specifically associated with the unit of area known as the *tsubo*.
