See the course notes for the section 'The'.
Following a vowel, 'the' is 'r:
- i + yr -> i'r (to the, for the, etc)
- i'r gwaith - to work, to the work
That would need a different tense, the simple past. The tense with wedi is the perfect tense:
- 'I have gone...' - perfect tense - Dw i wedi mynd...
- 'I went...' - simple past tense - Es i... (taught later in the course)
I answered "I am going to work" but it still counted it incorrect. There are too many different definitions for the same words. How do I know which context I'm supposed to translate in?
Dw i wedi mynd... is the perfect tense - 'I have gone...'.
Dw i'n mynd... is the present tense - 'I am going...'.
wedi in this context indicates a completed action. yn/'n in this context indicates an incomplete action.
