"Please may I have a drink?"
Translation:Os gweli di'n dda ga i ddiod?
This chapter introduces the concept of initial consonant softening (often referred to as 'Soft Mutation) which is unique to the Celtic languages.
This occurs in various places in the language for various reasons which are explained throughout the course.
This has developed to make the language easier to say and to flow better.
Compare saying 'Ga i diod' with saying 'Ga i ddiod' (you can try them in Ivona.com with Gwyneth if you're not sure of pronunciation).
There are extensive notes available in the web version of the course on Duolingo.
