The term "inborn character" refers to the natural or inherent traits, tendencies, or qualities of an individual. Some antonyms for this phrase may include learned behavior, acquired characteristics, developed traits, or nurtured tendencies. These antonyms suggest that an individual's character can be shaped and molded through various external factors such as upbringing, education, environment, and experiences. Unlike inborn character, which is believed to be inherent and immutable, learned behavior implies that individuals can adapt and learn new ways of thinking, behaving, and reacting to different situations. Therefore, while inborn character may be perceived as predetermined, learned behavior offers the possibility of change and growth.
