"Partially" means to some extent or in some degree, but not completely or totally. It is used to describe something that is incomplete or not fully developed. For example, a building that was damaged in a fire may be partially destroyed. Similarly, a dish that is not fully cooked may be described as partially cooked. The opposite of partially is wholly or entirely. It is important to note that "partially" and "partly" are interchangeable to some extent, but "partly" should be used when referring to a part or parts of something, while "partially" is preferred for the meaning "to some extent".
