The kanji 乙乙 is a pictograph. It depicts a curved object or the initial bend of a sprout emerging from the ground. Over time, it came to represent "second" or "the other" due to its position following "first" (甲, kou), as well as to represent a secondary status or a part that is following. Its form has remained relatively consistent throughout its evolution.
