易 (yì), meaning "easy" or "to change," underwent a fascinating transformation from its original pictograph of a蜥蜴 (lizard) to its modern simplified form, which retained only part of the traditional character while shedding the 虫 (insect) radical entirely. The simplified version preserves the essential strokes that suggest the creature's wriggling form, now freed from its original animal meaning and devoted entirely to abstract concepts of simplicity and transformation. In contemporary usage, 易 appears in 容易 (easy), 简易 (simple), 交易 (trade), and 改变 (change), carrying forward its ancient sense of fluidity and ease into the modern Chinese lexicon.
