"I saw you yesterday."
Translation:Gwelais i chi ddoe.
What is the difference between saying 'gwelais i chi ddoe' and 'wnes i weld chi ddoe', and when do I use what?
Two different ways of saying the same thing, really. gwnes i'ch gweld chi... is very common in the spoken colloquial language, but gwelais i chi... is also commonly used in the spoken and written language. You will hear and see both - it is more a matter of personal style than anything else.
Thanks, Ibis. This input from native speakers is invaluable. I did Welsh for years at school but this question had me stumped.
No, fi is not used like that.
The basic form is Gwelais i .... Some people in some areas and in some levels of formality sometimes put Fe or Mi in front of a positive statement - this cause a soft mutation of the verb:
- Fe/Mi welais...
In the modern language this Fe/Mi has no connection with the person doing whatever the verb is describing - I, you, they, she, Fred, the dog, ...
