Hi all! Can anyone help - I completed level 2 and am doing the final challenge each week to revise. But would like to re-do the lesson which had the contractions of nath o ddim - nath’om or wnest tI ddim - wnes’tim (that’s how it sounds! ) But am not sure which challenge this was as I haven’t got print outs of the course. Can anyone advise?! Diolch 
Hi Jenny,
“nes ti’m dweud” is introduced in lesson 22 at about 18.50. minutes. Lesson 23 starts with “doedd hi’m eisiau”. I don’t know, when “nath o’m” is introduced, I hope that helps a bit.
