Is there not a preposition missing i.e. 'to'/'i'. Shouldn't the sentence be 'Taswn i'n gyfoethog, byddwn i'n teithio i America'?
Yes, if it meant 'to travel to America'. 'To travel America' means to travel round America, and the expression can be the same in Welsh:
Then why not say "travel round America"? I have never heard "travel America" in a lifetime of using BE.
I have never heard that idiom in English except for "to travel the world" I hesitated over travel to and travel in and nearly used the latter but I expect that wouldn't have been accepted either.
Ah I see, thanks
