In Welsh, the digraphs 'CH', 'DD', 'FF', 'NG', 'LL', 'PH', 'RH' and 'TH' are regarded as single letters and listed separately in the Welsh alphabet, therefore 'CHWE', 'TACH' and 'RHAG' are three-letter abbreviations as well. The modern Welsh alphabet (yr wyddor) contains 28 letters, of which eight are digraphs. The letters 'J', 'K', 'Q', 'V', 'X' and 'Z' are not part of this alphabet. However, due to several loanwords from English the letter 'J' is now often included in the alphabet. The letters 'K', 'V', 'X' and 'Z' are used in some technical terms, like 'kilogram', 'volt', 'xeroser' and 'zero', but can be, and often are, replaced by Welsh letters: 'cilogram', 'folt', 'seroser' and 'sero'.

Welsh ('Cymraeg' or 'y Gymraeg') is a member of the Brythonic branch of Insular Celtic languages spoken natively in Wales (Cymru), in England by some along the Welsh border and in the Welsh immigrant colony in the Chubut Valley in Argentine Patagonia.

In 1992 Kelvin Downey built a Welsh Calendar Cube based on the layout of the English Calendar Cube. The design was reworked in 2008 by Walter Randelshofer and Kelvin Downey.
