 Following common usage (cf Pelletier &amp; Schubert 1989), we will occasionally label linguistic items with mass features by ‘+MASS’, and those without by ‘-MASS’, and those with count features by ‘+COUNT’ and without by ‘-COUNT.’ As will become clear, an expression’s being mass or count are not always mutually exclusive, and neither is the distinction exhaustive. There are indeed cases of +MASS/+COUNT (e.g. ‘hair’, ‘fish’), or -MASS/-COUNT (e.g. ‘fireworks’)). This ends the preliminaries.
