Eddy
Eddy is a diminutive or nickname form of the masculine name Edward. Edward is derived from the Old English name 'Ēadweard', which is composed of the elements 'ēad' meaning 'wealth, fortune' and 'weard' meaning 'guard'.
The name Edward has been a popular name in England since the Middle Ages, borne by several English kings including Edward the Confessor and Edward I. It became even more widespread after the Norman Conquest of England in 1066 due to the popularity of the name among the Norman nobility.
The shortened form Eddy emerged as a nickname for Edward, likely in the 19th century when nicknames became more common. Eddy is a casual, friendly diminutive that has also been used as a given name in its own right.
While Eddy is considered a masculine name, it has sometimes been used for girls as well in recent years, reflecting the growing trend of unisex names.
