"Blend of Avery and Leigh"
The name Averleigh is commonly a female name from the "English" origin.
Averleigh is a modern American formation from the given name Avery plus the ending -leigh, a spelling of Leigh that recurs in twenty-first-century US coinages such as Everleigh and Paislee. Its first appearance in US birth records, in 2012, fits a recent formation rather than an inherited name. Avery derives from an English surname, and Leigh is an English place-name element from Old English leah, meaning clearing or meadow.
The pronunciation of Averleigh is AY-ver-lee.
