Wiktionary:About Middle Welsh

Special characters for Middle Welsh

 * ð: Wherever Middle Welsh spelling uses ⟨d⟩ to represent the sound, our entry uses ⟨d⟩ in the page name, but ⟨ð⟩ in the headword line as well as in links. For example, the page name ' says arglwyð in the headword line, and links like wlm point directly to '. This is a fairly common practice in scholarly works about Middle Welsh; the characters ⟨ꝺ⟩ (insular d) and ⟨ẟ⟩ (Latin delta) are also often found in this capacity, but ⟨ð⟩ has better font support.
 * ỻ and ỽ: Entries do not use these letters; use ⟨ll⟩ and ⟨w⟩ respectively instead. (This is in concordance with Wiktionary practice for long s ⟨ſ⟩ and wynn ⟨ƿ⟩, which are also not used in entries.)

Sorting in categories
Following the usual practice of Middle Welsh glossaries, the letter k is automatically sorted as c in Middle Welsh categories. In addition, the sort parameter should be used to sort out the various uses of u, v, and w: when any of these is used to represent the sound, set sort to the spelling using ⟨u⟩; when they're used to represent , set it to the spelling using ⟨v⟩; and when they're used to represent or , set it to the spelling using ⟨w⟩.
