High descent refers to a family's prestigious lineage, often marked by their social status, wealth or power. However, there are several synonyms that can be used to convey similar meanings, such as nobility, aristocracy, elite, royalty, upper class, blue blood, and high society. Each of these terms emphasizes the sense of importance and high status attributed to individuals from such a lineage. Other synonyms could include the phrase 'wellborn', which refers to a person who is born into a family of high social status, or 'patrician', which denotes an individual who has high social standing and is associated with the upper classes. Ultimately, the use of these synonyms depends on the connotation one wishes to convey and the context of the sentence in which they are used.
