One of the correct answers was without the soft mutation of 'mi' to 'fi'. Is that a mistake or is it an optional mutation?

October 19, 2016


Both are used.

Why do we need the ag here. I learned it as rhaid i fi beidio yfed

The full form of 'beidio' is 'beidio â'.

This changes to 'beidio ag' in front of a vowel.

However in speech and in most modern adult courses the form used is just 'beidio'.

We've used the 'beidio â/beidio ag' form here since it's important to recognise it, however leaving it out is also accepted as a correct answer.

If I wanted to say, "I don't have to drink", rather than, "I must not drink," would it be: "Does dim rhaid i fi yfed"?

Yes - see the examples in the course notes.

  • Dw i'n edrych am dŷ newydd - I'm looking for a new house

Is there a difference between 'does dim rhaid i fi yfed' and 'rhaid i fi beidio yfed'?
