I'm still working on improving my Welsh because I'm determined to make the transition from reasonably fluent learner to confident speaker. Most problems now are lack of vocabulary where I start talking about something and realise half way through a sentence that I don't know the words I need.
Like this morning in the conversation group I didn't know the word "foundations" when I was trying to describe an old building we lived in once. It's difficult to know in advance what we might be talking about, so difficult to prepare, but I need to see if I can prepare a bit more by choosing something that I did the previous week or something interesting that I've heard about and look up the necessary vocabulary so I can talk fluently about it when I get the chance.
