Little darling or dear one
Darleny is a modern elaboration of the English word 'darling', likely influenced by Spanish naming patterns that add the 'y' or 'ie' suffix for a diminutive, affectionate feel. It functions as a rhythmic, feminine variant of Darlene, which gained popularity in the mid-20th century. While it has roots in Old English 'deorling', this specific form is most common in Hispanic-American communities.
