Chailey is a unique and distinctive given name of Welsh origin, derived from the ancient personal name Cadel. It has gained popularity as a girls' name but can also be used for boys. The name Chailey is composed of two elements: 'cael', which means 'battle' or 'war', and 'i', a suffix that denotes nobility or high rank. Therefore, the name may be interpreted to mean "noble in battle" or "of noble warrior stock". In Wales, the name has been used for centuries but it is still relatively uncommon, adding to its charm and uniqueness. Chailey is often spelled with an 'i' at the end, although variants such as Caylee and Chailee are also seen. It does not have any specific associated days or personality traits, allowing those named Chailey to create their own identity and legacy.
Chailey had a significant gap in births between 2001 and 2012, with no recorded births in the intervening decade. The most recent data shows a steady but low number of babies named Chailey each year since then.
