The major headline for British baby names in the last decade has undoubtedly been the rise of diminutives as given names. Alfie, Archie, Charlie, Tommy, Evie, Millie, Maisie and many others are boundless in our playgrounds as parents opt for cheerful and breezy short forms. But this phenomenon is certainly not confined to the English language — Wales has also been getting in on the act of reviving vintage pet forms and putting them ‘up front’ on birth certificates.

　　Here is a typical Welsh birth announcement from 2013 to illustrate: Ionawr 14eg, 2013 Croeso mawr i Nico Llwyd mab i Berwyn ac Awel a brawd bach i Bedo, Nanw a Nel. Translation: “January 14th 2013. Welcome to Nico Llwyd, son of Berwyn and Awel and little brother to Bedo, Nanw and Nel.”

　　Several Welsh diminutives, such as Dai, Bethan and Megan, are as established as first names as Jack, Harry, Elsie. This piece, however, does not aim to look at the long established and emancipated Welsh diminutives but rather delve into vintage Welsh pet forms which are now taking on new life. Some are indigenous Welsh nicknames, shortened from indigenous Welsh names; some are wholly Welsh pet forms of ‘English’ names; and others are established “Cymricised” forms of familiar English nicknames.
