This is my first introduction to the word "jardin". Does the word really mean both garden and yard. To me entering someone's garden or yard are two different things. I use a lawnmower to cut the yard but the garden?
We have always used the word "yarda" for yard and "jardin" for garden at my house. I put yarda for yard and DL says wrong. I have never heard jardin used to describe the front or back yard of someone's home.
