Meaning & History
Kay is a short form of Katherine and other names beginning with K. As a diminutive, it emerged in the English-speaking world as a casual, affectionate abbreviation, likely influenced by the similar Kate. Throughout the 20th century, Kay has also been used as an independent given name, especially in the United States.
Etymology and Origins
The root name Katherine has a debated etymology. It likely derives originally from the Greek name Aikaterine, with possible origins in the Greek word for "torture" (aikia) or the goddess Hecate.

Kay inherits this root meaning indirectly, as it is a shortened form of Katherine.
