Other forms: desisted
To desist is to stop doing something. Desist from it, cease and desist, desist immediately.
It is formal and legal, and it appears in ordinary life almost only in cease and desist, the American phrase for a letter demanding that somebody stop — the doubling is a legal habit of pairing an English word with a French or Latin one. It takes from. Note that desist comes from the Latin for standing away, the same sistere as in resist, insist and consist.
