Popular nicknames may be used on their own on the birth certificate or might be short forms for proper names ranging from the common to the unusual.
The nicknames here rank highly on both the US and the British lists of popular baby names. These top nicknames are friendly and likeable, but may be much more widely-used than you guess given that they're used as diminutives for such a broad range of names. Don't be surprised if your little Ellie or Jack is one of many on the playground!
The up side of these popular nicknames is that they make any name friendlier and more accessible. So you can choose a name of a mythological hero or a great-great-uncle and make it friendly in the contemporary world through one of these top nicknames.
