The term "acquired" describes something that has been gained, obtained, or developed rather than being present from the start. It can refer to physical objects that someone has bought or received, such as acquired property or assets. It is also commonly used for non‑material things like skills, knowledge, habits, or characteristics that a person develops over time through experience, education, or practice. In medicine and biology, "acquired" contrasts with "congenital" or "innate" and refers to conditions or traits that appear after birth as a result of environmental influences, lifestyle, or exposure, such as acquired immunity or acquired diseases.
