The name Dave is a boy's name of Hebrew origin meaning "beloved". Dave and is often added to lists like Labrador Retriever Names and discussed in our forums with posts like "Change one letter (5 names)".
From the experts:
Dave is the ultimate good guy name, but where father name David is still holding onto a spot in the Top 20, Dave -- widely used as an independent name in the middle of the last century -- dropped off the Top 1000 a few decades ago and shows no signs of a comeback. Baby Davids today, often named for dad or grandpa, are more likely to be called David than Dave.
