Brian says: Gad i fi fynd ato fo i weld os ydy o'n iawn.
We have already come across the more formal form: Gadewch i fi The informal form is:
Gad i fi or Gad i mi means let me
Gad i fi weld - let me see
Other forms of this construction are:
Gad iddo fe/Gad iddo fo Gad iddi hi Gad i ni Gad iddyn nhw
Note also that Brian said Gad i fi fynd ato fo i weld os ydy o'n iawnLet me go to him to see if he's alright.
Though very common in everyday speech this construction is not strictly correct
When if conveys the meaning 'whether' the form is 'a'
So strictly speaking Brian should have said: Gad i fi fynd ato fo i weld a ydy o'n iawn
Pam na/Pam dwyt ti ddim
There are two ways of conveying the negative form of the verb when it follows the question 'why'. For example:
Pam dwyt ti ddim yn gwisgo cot ? or Pam nad wyt ti'n gwisgo cot? Why aren't you wearing a coat? Pan na wnei di wrando? or Pam wnei di ddim gwrando? Why don't you listen? Pam na fyddi di yn y tŷ heno? or Pam fyddi di ddim yn y tŷ heno? Why won't you be in the house tonight? Pam est ti ddim? or Pam nad est ti? Why didn't you go?
Note the following Na is used before a consonant and nad before a vowel Na causes a soft mutation Pam na wnei di If you are using the na/nad construction there is no need to use ddim after the verb.
Wyt ti wedi + Do/Naddo
You will have learnt, I'm sure, that answers to the question Wyt ti or Ydych chi is YDW or NAC YDW. It's worth noting however that you might hear a different answers to Wyt ti wedi. For example if the question is Wyt ti wedi gorffen? The answer you'd expect would be ydw or nac ydw. Some people however answer these questions with Do or Naddo.
Wyt ti wedi blino? Do or Naddo.
Although not strictly correct the Do/Naddo answer is very common.
