Gail
Short for Abigail
Gail is a given name, typically feminine, that emerged as a shortened form of Abigail in the mid-twentieth century.
It peaked in popularity in the 1950s and 1960s: Gail was the third most popular girl's name in her kindergarten class.
The name has since declined but remains familiar among older generations. (Lowercase gail is a rare variant spelling of gale.)
