"May I have sweets and a drink?"
Translation:Ga i losin a diod?
"May I have a drink"="Ga i ddiod". Here it has mutated due to it being the first subject of the verb "Ga". (A way people remember to mutate it here is because it comes after a pronoun). In "May I have an omelette and a drink" ("Ga i omled a diod") it does not mutate due to it coming after "a".
The object of ga i...? mutates - but only the first letter of it. For example, in:
- Ga i losin a diod the object is losin a diod, but l has no mutated form.
- Ga i beint o gwrw a brechdan the object is peint o gwrw a brechdan and so the p- mutates to b-. (The c- of cwrw is mutated because it follows o.)
