to disguise oneself as
🥸 伪 = fake/false + 装 = to dress/clothe: fake-dressing = a disguise
伪 carries the sense of false or counterfeit, and 装 means to put on clothes or dress up. Together they form putting on false clothing, i.e. disguising oneself or pretending to be someone you are not.
装 — clothes 衣 + strong 壮 (phonetic)
装 is a semantic-phonetic compound. The bottom 衣 ('clothes') gives the meaning, since the original sense was packing or dressing—putting clothes or goods into a bundle. The top 壮 supplies the sound. Meanings extended from 'to dress/attire' to 'to load, install, pretend'.
