Perspicacity (also called perspicaciousness) is a penetrating discernment (from the Latin perspicācitās, meaning throughsightedness, discrimination)—a clarity of vision or intellect which provides a deep understanding and insight. It takes the concept of wisdom deeper in the sense that it denotes a keenness of sense and intelligence applied to insight. It has been described as a deeper level of internalization. Another definition refers to it as the "ability to recognize subtle differences between similar objects or ideas".
