divination sign, land, earth
坤 centers on the receptive, yielding aspect of the earth, especially as one of the eight trigrams in divination. It represents land, soil, and the passive principle in contrast to the active, creative force.
坤 combines 土 (earth) with 申, which likely contributes the sound and may relate to extending or stretching, suggesting the expansive, receptive nature of the earth.
The left side 土 is earth, and the right side 申 looks like a field with a line through it. Picture the earth as a vast, receptive field that yields to the plow, embodying the passive, nurturing land of the 坤 trigram.
For コン, imagine a con artist trying to sell you a piece of land: con -> コン, and the earth (坤) is the passive, yielding ground they claim to own.
