in that that it cannot be pluralized in this position (*the boys actor). However, boy is more like a noun than an adjective in that it cannot be modified by very (*the very boy actor) as adjectives typically can be and in that it cannot be separated from the head noun by an adjective (*the boy talented actor). Further, boy is more like a noun in that it cannot occur alone as a subject-related predicative complement (*the actor is boy). The Cambridge Grammar of the English Language classifies words like boy as nouns. John Robert Ross similarly classifies it as an "adjectival noun", a noun with some adjectival properties. Color terms also exhibit features of both nouns and adjectives. In many cases, the category of these terms can be clearly identified. For example, color terms used as subjects (blue represents hope) or complements (my favorite color is blue) appear to be typical nouns while color terms occurring attributively (the blue light) appear to be typical adjectives. Similarly, color terms marked as plural (the blues in his paintings) appear to be nouns while those marked as comparative (bluer) or superlative (bluest) appear to be adjectives. However, James D. McCawley notes a case in which color terms appear to have features of nouns and adjectives at the same time: a deep blue necktie. In this case, the modifier of blue is an adjective (deep) rather than an adverb (deeply), which suggests that the color term is a noun. However, its function appears to be the same as the blue in the blue light, which is an adjective. Bas Aarts notes that this apparent dual categorization can be avoided by treating phrases like deep blue as adjective-adjective compounds. Phrases like the lucky in the lucky don't need to diet also present challenges. Words like lucky in this case have features typical of a noun; specifically, they appear to head phrases that (1) contain determinatives and (2) have the prototypical functions of noun phrases (such as subject, in this example). However, these words also have features of adjectives. For instance, they can be modified by very (the very lucky don't need to diet) and combine with morphemes that can typically attach only to adjectives, such as un- (the unlucky must diet). Complicating matters further, they can take as pre-head modifiers either adjectives (the ostentatious rich) or adverbs (the completely innocent). Aarts argues that phrases
