"I was raised in the Roman Catholic Church."
Translation:Ges i fy magu yn yr Eglwys Gatholig Rufeinig.
It should be. Ces i is routinely mutated to ges i, but it is not wrong to use the basic form.
So does that mean that in affirmative sentences it is normal in speech to mutate a verb that begins the sentence?
Some people do, some don't. It is particularly common with cael - ges i, gest ti, ...etc. If you avoid doing it for now with other verbs it will be easier to get into the routine of the patterns:
- Des i yma - I came here
- Ddes i yma? - Did I come here?
Ddes i ddim yma - I did not come here
Prynais i gar - I bought a car
- Brynaist ti gar? - Did you buy a car?
- Phrynodd hi ddim car - She did not buy a car
In the wild, ges i... is very common for the statement as well. This is because many people would put mi or fe in front of a statement verb, and that causes a soft mutation. For example:
- Mi/Fe ges i frecwast - I had breakfast
And the soft mutation is often kept even if fe/mi is not used. It seems particularly common for some reason with forms of cael and gwneud.
