Orthography
Welsh is written in a Latin alphabet traditionally consisting of 28 letters, of which eight are digraphs treated as single letters for collation:
- a, b, c, ch, d, dd, e, f, ff, g, ng, h, i, l, ll, m, n, o, p, ph, r, rh, s, t, th, u, w, y
In contrast to English practice, "w" and "y" are considered vowel letters in Welsh along with "a", "e", "i", "o" and "u".
The letter "j" is used in many everyday words borrowed from English, like jam, jôc "joke" and garej "garage". The letters "k", "q", "v", "x", and "z" are used in some technical terms, like kilogram, volt and zero, but in all cases can be, and often are, replaced by Welsh letters: cilogram, folt and sero. The letter "k" was in common use until the sixteenth century, but was dropped at the time of the publication of the New Testament in Welsh, as William Salesbury explained: "C for K, because the printers have not so many as the Welsh requireth". This change was not popular at the time.
The most common diacritic is the circumflex, which disambiguates long vowels, most often in the case of homographs, where the vowel is short in one word and long in the other: e.g. man "place" vs mân "fine", "small".
