"Blend of La and Dale"
The name Ladale is commonly a male name.
Ladale has the form of the prefix La- plus the name Dale, a combination pattern found in twentieth-century American given names. Dale is an English surname-derived name, and the La- element works as a prefix here rather than carrying a meaning of its own. US birth records show Ladale from 1957.
The pronunciation of Ladale is luh-DALE.
