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.

simp. and trad.		易
2nd round simp.		𠃓

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.
