2.2 Remarkable in a good sense: a.2.a Of persons and personal qualities: Distinguished, eminent, excellent, renowned. Obs. (exc. in humorously pedantic use). b.2.b Of things: Remarkably good or great. Of events and utterances: Striking, significant. ? Obs. 3.3 Remarkable in a bad sense; gross, flagrant, outrageous. [This sense does not belong to L. egregius or to It. egregio; prob. it arose from an ironical use of 2, though our earliest quotations afford no evidence of this.] a.3.a of persons and personal attributes.(emphasis added)
