why cant i do a fyddi construction?
Fyddi di...? would more 'Will you be giving me a lift?' than 'Will you give me a lift, (please)?'
For a future Tree we will try and add the '...,please?' to make it clearer.
Gwnaf not accepted?
I think it is. At least, I wrongly put "wnaf" and was corrected to "gwnaf"!
