Why is "dydd Llun" not mutated here?
It can be said that way colloquially, and it's closer to the Welsh. "Correct" English is also accepted.
Can someone give me a full conjugation for all pronouns for 'to be', 'to have', 'to come' and 'to do' for present and past tense?
I've tried to search on Google Images but I could not understand anything since it is lack of sources.
Wiktionary has conjugations of verbs from many languages, including Welsh, on the English version (the biggest challenge, though, is working out how to interpret the conjugation charts...)
