🏗️ 工 = work + 地 = ground/land = work-ground = construction site
工 means work or labor (also seen in 工人 worker, 工作 work). 地 means ground, land, or place (also in 地方 place, 地图 map). Together: the ground where work happens.
地 — earth 土 + 也 (phonetic)
地 is a semantic-phonetic compound. The left component 土 means 'earth' or 'soil' and gives the meaning, while 也 on the right hints at the pronunciation. Originally referring to the ground or land, it broadened to mean 'place,' 'region,' and 'territory.'
