Martin (1992: 315):
Similarly, whereas Classifiers elaborate the Thing, Epithets add qualities. These may be of an experiential or attitudinal kind:
Table 5.12. Extension in the nominal group NominalGroup epithet + thing epithet + thing (attitudinal) red car ugly car big lunch chauvinist pig round ball pleasant spot speeding bullet beautiful shot hungry puppy greedy kitten
 In every case, the expansion relation between the Epithet and Thing is elaboration, not extension. This is demonstrated by the agnate relational clauses, all of which are intensive (elaborating), not possessive (extending): the car is red/ugly, the lunch is big, the ball is round etc.
 This is a Classifier, not an Epithet, as shown by the fact that, unlike Epithets, it can't be intensified as a very speeding bullet.
