My answer was "I made breakfast". I believe this should be an equivalent answer? In practical English "have" is usually negated.
In Welsh we differentiate between the perfect 'dw i wedi gwneud' (I have made/I've made)
and the past 'Gwnes i' (I made).
Dw is the verb. It is the 1st person singular of Bod right?
Gwneud is a cognate of English work, Greek έργο (érgo, "work" [root present in ergonomics, organ and lethargy]), Albanian argëtoj ("I entertain"), Armenian գործ (gorc, "work") and Persian ورزیدن (varzidan, "to exercise").
It took me a while before I could tell what the personal pronoun was. I thought that Dw was the word for I until I looked it up on the internet.
What does "Dw i wedi blino" then mean? "I have made tiredness"?
