Is the "dw" short for "ydw" - I recall being taught to use ydw in school for the same phrase at GCSE.
so if dw i means I am, what's dw i'n?
"Dw i'n" (or the non-shortened version "Dw i yn" is used in front of a verb to say you are doing something. Examples: "Dw i'n mynd" = "I am going" or "I go". "Dw i'n hoffi" = "I like" or "I am liking".
I'm here for your parsnips
Kitty Cheshire dw i.
It doesn't help if you're dyslexic!
I was told Welsh is VSO. Is this wrong all the time, or only with names?
I think it is by default, but you can "front" the object to add emphasis to it.
I am Welsh and it should be ydw I not dw I because you say dw I ddim yn hoffi pêl droed (which means I don't like football) dw I means I but ydw I is I am
Dw i is a common form used to say ‘I am’. It is the basic form taught on many introductory Welsh for Adults courses in Wales.
Many schools teach the slightly more formal Rydw i as the basic form for ‘I am’. This course also accepts that.
