Template talk:cy-adj

This template consistently produces incorrect equative forms
At the moment this template creates equative forms of "-ach" adjectives by adding "-ed" e.g. "glas > glased" and of "mwy" adjectives by adding "cyn" (plus specifies the need to include the mutation separtely) e.g. "gogleddol > cyn ogleddol". Both of these forms are wrong. The "-ach" adjectives take "cyn" and the "-ed" ending e.g. "glas > cyn lased" and "mwy" adjectives take "mor" not "cyn" e.g. "gogleddol > mor ogleddol". Also, as seen here, both "cyn" and "mor" require a soft mutation but not of "ll" or "rh" e.g. "rhad > cyn rhated", "llwyddiannus > mor llwyddiannus". Can this be corrected as it's created a whole load of incorrect forms? Secondly, is it possible to write this mutation rule into the template so that it does it automatically?

 * Getting the mutation to be automatic will be tricky, but I'll see if I can figure something out over the next few days. What about irregular forms like ; is that right? Or should it be ? Are there any one-word equatives that don't take or ? —Mahāgaja · talk 10:19, 4 March 2020 (UTC)
 * Irregulars like cystal don't need the cyn - that's the cy- bit in the word. Others include cynted (possible equative of cynnar "early" and cyflym "fast"), cynddrwg (of drwg "bad"), cyhyd (of hir "long"), cyfled (of llydan "wide"), cymaint (of mawr "big"), cyfuwch (of uchel "high"). (The same suffix is even used with the noun nifer "number" to make cynifer "so many".) Many of have secondary more regular forms too e.g. lleted, hired, cyflymed. You can see a list of irregulars here.
 * Looking at that list I did wonder whether the equative form should include the cyn in the declension (is that the right word for comparatives?) or not e.g. glased insted of cyn lased. That said, the form with cyn itself is quite formal - colloquial language can use mor for (almost?) all, so for "so blue", cyn lased is formal, mor las is normal. The forms without the cyn, so just glased, are even more formal or poetic! I'd suggest including the cyn as we're also including mor, mwy, mwyaf in the other declension and because you can't separate the cyn-, cy-, cyf- part from irregulars (there's no *stal from cystal).
 * Thanks very much for looking into this. Llusiduonbach (talk) 14:11, 4 March 2020 (UTC)
 * The reason I asked is that with the parameters as they currently are, there's no way to display "cyn ogleddol" at but "cystal" at, so more tweaking is needed. I feel like this is something we need a module to do, but I don't know how to write modules. —Mahāgaja · talk 14:17, 4 March 2020 (UTC)
 * Oh right. So it can show mwy(af) gogleddol but can't show mor ogleddol? Llusiduonbach (talk) 14:26, 4 March 2020 (UTC)
 * At the moment, eq is being used to show both the equative ending and the mutation. So I could edit the template to give "mor ogleddol", but then it would also give *"mor cystal" or *"cyn cystal". —Mahāgaja · talk 14:32, 4 March 2020 (UTC)
