English is not my first language, and in my language (Bosnian) we write just as we speak ; so from time to time, I encounter phrases which I know I have heard before, but am not sure if I am writing them correctly.
Do you say sound approach to describe an approach to a problem which is logical, makes sense, and is practical?
The reason I ask is that I could not find it in a reliable online reference, and I have a feeling that I am spelling it wrong.
