What Lenny Means
Lenny means brave as a lion, or lion-strong. The second element means hardy and courageous rather than physically hard, so the pairing describes a temperament rather than a build.
Where Lenny Comes From
Lenny shortens Leonard, from the Germanic Leonhard — leon, borrowed from the Latin for lion, and hard, brave or strong. Saint Leonard of Noblac, a sixth-century Frankish hermit, became the patron of prisoners and women in childbirth, which spread the name across medieval Europe. The Normans brought it to England. Lenny and Lennie emerged as familiar forms, and in Britain the pet form is now registered far more often than Leonard itself, following the same pattern as Alfie, Freddie and Albie.
