### Glyph origin

Historical forms of the character 易 :
| Shang | Western Zhou | Warring States | Shuowen Jiezi (compiled in Han) | Liushutong (compiled in Ming) |
| Oracle bone script | Bronze inscriptions | Chu slip and silk script | Small seal script | Transcribed ancient scripts |
| | Old Chinese |
| 賜 | *sleːɡs |
| 儩 | *sleɡs |
| 舓 | *ɦljeʔ |
| 易 | *leːɡs, *leɡ |
| 敡 | *leɡs |
| 鬄 | *sljeɡ |
| 睗 | *hljeɡ |
| 晹 | *hljeɡ |
| 痬 | *leɡ |
| 蜴 | *leɡ |
| 埸 | *leɡ |
| 逷 | *l̥ʰeːɡ |
| 剔 | *l̥ʰeːɡ |
| 踢 | *tʰeːɡ |
| 惕 | *l̥ʰeːɡ |
| 錫 | *sleːɡ |
| 裼 | *sleːɡ |
| 緆 | *sleːɡ |
Oracle bone script and bronze inscriptions: a pictogram (象形) of a filled container, the original form of 賜 (OC *sleːɡs, “to confer, to bestow”). Possibly specialised from 益 (OC *qleɡ, “to increase, to add”). Perhaps borrowed phonetically to mean "easy".
The character is not the pictogram of a chameleon, as folk etymology says. Unrelated to 陽 since it doesn't represent the sun.

### Etymology 1

From 移 (OC *lal, “to change; to alter”) + k-extension (Schuessler, 2007). The meaning of "change, alter" is linked to "give, bestow" since something given by somebody to somebody else "changes" its owner.
This etymology is incomplete. You can help Wiktionary by elaborating on the origins of this term.
