Orthographic borrowing from Chinese 化學 / 化学 (huàxué, literally “change + study”).[1]

Superseded older term 舎密 (seimi).[1][2][3]

| 化學 (kyūjitai) |
Reanalysis of 化学 (kagaku) above, as a compound of 化け (bake, 連用形 (ren'yōkei, “stem or continuative form”) of the verb 化ける (bakeru, “to transform”)) + 学 (-gaku, “-logy, -graphy”). Alternative reading sometimes used to differentiate 化学 (kagaku) from 科学 (kagaku, “science”), which it has become an exact homophone of.[1][2][3][4][6]
First cited to a 1967 novel by 大原富枝 (Ōhara Tomie).[1]
