The use of ‘stress’, which refers to a physical reality, instead of ‘accent’ is apt to confuse even competent scholars and make them speak of intonation as soon as they fancy they are hearing pitch instead of stress: for many of them, the difference between 'to increase' and 'an increase' would be due to a different placing of stress, while that between 'a móving van' (a van used for moving furniture) and 'a moving ván' (a van in motion) results from the use of a different intonational contour.
