"Blend of Anna and Lynn"
The name Annalyn is commonly a female name from the "English" origin.
Annalyn is a modern English formation that joins Anna, the long-established form of Hannah, with Lynn, a name that comes from the Welsh word for lake. It follows the pattern of American names that add the -lyn element to a shorter given name, as in Kaylyn and Ashlyn. The name first appears in United States birth records in 1972, which fits a twentieth-century coinage rather than an inherited traditional name.
The pronunciation of Annalyn is AN-uh-lin.
