Historical forms of the character 外
Shang	Western Zhou	Shuowen Jiezi (compiled in Han)	Liushutong (compiled in Ming)
Oracle bone script	Bronze inscriptions	Small seal script	Transcribed ancient scripts

Phono-semantic compound (形聲／形声, OC *ŋʷaːds) : semantic 卜 + phonetic 月 (OC *ŋod).

According to 学研漢和大字典 (Kenkyūsha Kanwa Dai Jiten), it is also an ideogrammic compound (會意／会意) ; 月 originally represents a crescent moon (i.e. the moon with part “missing” to the observer). The character is thus interpreted as representing divination based on the partial phase of the moon, implying the remaining visible part of the moon is the moon's ‘outside’. (Can this⁽⁺⁾ etymology be sourced?)
