 Even within English often the use seems arbitrary, where the following illustrate cases where either (i) the choice to use a +MASS/-COUNT or -MASS/+COUNT term is (usually) arbitrary on the occasion of use, or (ii) where a contrast is given (e.g. between fruit and vegetables) where one can see that our decision to make the default noun mass and another count is arbitrary, since there is no inherent mass/count difference in the referents. (These examples, and the point, are from Pelletier 1989 p19, and 2012 p429, and Gillon 1992 p.627, 2012 p.721).
