noun
divination sign; hexagram
Refers to a sign or symbol used in divination, especially the hexagrams of the I Ching (易経). Often used in the context of fortune-telling.
易者が卦を立てて占った。
The fortune-teller cast a hexagram and divined.
この卦は吉と出た。
This divination sign came out as good luck.
占い is the general term for fortune-telling or divination, while 卦 specifically refers to the signs or hexagrams used in such practices.
易 is the I Ching or the art of divination based on it; 卦 are the individual hexagrams or signs within that system.
The kanji 卦 is composed of 卜 (divination) and 圭 (a jade tablet, here possibly phonetic). The reading け is the Sino-Japanese on'yomi.
