My understanding of French is a strange one. I did french in school but not to a high standard. I have spent a lot of time in France and I knew enough of the language to get by (
Parlez vous Anglais?
), I would listen to french tv and radio and I can understand French, if there were a conversation in french I could understand its context, when someone spoke to me 7 times out of 10 I knew what they were saying.
However....when it came to responding and speaking french myself I am hopeless, I know the keywords but can not construct them into a sentence. My mind gets hopelessly confused and I end up speaking a mismatch hybrid of welsh/english/french and spanish all at once where the listener would look at me bewildered at the nonsense I have just said which makes no comprehension in any language

. I found in these instances it was best to either just speak English or to speak single French words only(like a 3 year old).
