The phrase "of good breed" is often used to describe someone or something that comes from a high-quality or prestigious lineage. There are several synonyms that can be used to convey this same idea, such as "well-bred", "blue-blooded", "high-born", or "noble". These terms suggest that the subject is of a superior class or pedigree and often carries an air of sophistication and refinement. Other synonyms include "purebred", "thoroughbred", or "pedigreed", which may be used to describe animals or plants that come from a strong genetic line. Ultimately, these synonyms signify that the subject in question has a sense of exclusivity, luxury, and excellence associated with their lineage.
