"Bore dydd Gwener"
I'm not quite sure what the problem is here. The hints to this phrase show Bore = 'Morning' and dydd Gwener = 'Friday'
Which gives the answer 'Friday Morning'
Possibly these hints didn't appear when you did the exercise and that seems to be a bit of a random problem with the mobile app, which, unfortunately, we have no control over.
The hints give a translation, and the section on days of the week on the website has notes explaining them.
Even with new words, when you get audio you only get a translation when you get it right. I wish all the comment sections gave one at the top of the page. I know some do, but not all.
Please can we have a straight list of the days? I am struggling to take them on board by skipping around them - especially as they don't relate to the other languages I studied eons ago.....
