Renowned English author Evelyn Waugh pronounced his name "EEV-lin" (fun fact: his first wife, also named Evelyn, was referred to as "She-velyn"). But "EV-uh-lin" also works, and is probably the most familiar pronunciation of the name today.

Evelyn derives from the French feminine given name Aveline, which is from an obscure Germanic root which may mean "desired, wished for" or "water, island". The name Aveline was brought over to England by the Normans, but it first became popular as a masculine name – a transferred use of the surname Evelyn, which comes from the same source. Variations include Evaline, Evalyn, Evelin, and Eveline.
