Likely a modern combination of Shay and Lea
Shalea is a contemporary American name likely created by blending the prefix Sha- with the name Lea, or as a variation of Shayla. It combines the Hebrew roots of Shay, meaning 'gift', with the English or Hebrew roots of Lea, meaning 'meadow' or 'weary'. As a modern invention, it lacks a singular ancient etymology but carries a melodic, rhythmic quality popular in the late 20th century.
