Evaluative Binominal Noun Phrase (EBNP)

Evaluative Binominal Noun Phrase (EBNP)
Introduction III
(1) This whale of an institution (COCA)
(2) This oceanic barge of a woman
(3) Another bitchy iceberg of a woman (Aarts 1998: 132-133; Keizer 2007)
Evaluative Binominal Noun Phrase (Trousdale 2012) Expressive Binominal Noun Phrase (Foolan 2004) Binominal Noun Phrase (Aarts 1998; Keizer 2007) Adjective Noun (Ross 1973; McCawley 1987)
a comparison between Noun 1 and
Noun 2.
a property of Noun 1 is ascribed
onto Noun 2.
Noun 1 still syntactically a noun,
semantic functions an adjective.
Introduction III
• [N1 of a] reanalyzed as a modifier.
• Speaker-oriented.
• Qualifies a unspecified feature of N2.
• Requires a context and/or social/ cultural
knowledge to interpret. • Dixon’s Value Adjective (1982)/
Adamson’s Attributive Adjective (2000)
(4) It was a hell of a night for a meeting -- with the storm
going and the river about to blow.
(5) " Y'ever hear what Kennedy said three hours before he
was shot? " he asked, putting on his best Massachusetts
accent. " You know, last night would've been a hell of a
night to kill a President. "

Evaluative Modifiers (EM)
Evaluative Modifiers
“[…] subjective/objective polarity …modifiers relating to properties which are (relatively) inherent in the head of the noun phrase, visually observable, objectively recognizable or assessable, will tend to be placed nearer to the head and be preceded by modifiers concerned with what is a matter of option, imposed on the head by the observer, not visually observed and only subjectively assessable.” (Quirk et al. 1985: 1341) “A value adjective cannot directly qualify a noun; if it appears in an NP with a noun and no other adjective, then it has manner function with respect to an implicit non-value adjective.” (Dixon 1982: 30) “A much simpler explanation for the data Dixon reviews can be achieved by positing a semantic split within the adjective group, such that adjectives in categories 2-7 are descriptive or referent-orientated while adjective in category 1 – the VALUE class – are affective or speaker-oriented. Their function is not to describe properties in the referent but to express speaker-response to it.” (Adamson 2000: 44)

Research Question:
If you assume the existence of premodification zones, do the distribution
patterns of EM premodification provide evidence that the EM has integrated
into these zones?

analyzed as a modifier, there would be overall less EM examples with
premodification.

• Premodification in Classifier 2 and Descriptor 2 zones is a distinctive feature
• Premodification distribution would point
to a second construction.
• Loss of plural form and now the loss of
Classifier 1 modification would indicate
the loss of‘nounhood’ in Noun 1.
• Loss of Reinforcer 2 zone can be found
in earlier constructions.
• There seems to be evidence for the EM’s

Further steps
• Feist makes categorical distinctions that are problematic. Further work can still
be conducted in this area.
• Other variables such as register, genre, and time may also play a role and need
to be factored into the analysis.
• Include earlier constructions in the analysis.

Why Premodification?
1) Premodification patterns have been used other studies of ‘N of N’ as
evidence for separate categorization (e.g. Brems 2011) and no research
has as of yet been conducted on the premodification patterns of
evaluative modifiers.
2) It would also provide evidence of the ‘nouniness’ of N1 (Langacker
2010); a distinguishing feature of the EM from the EBNP (ten Wolde &
Keizer forthcoming.).
3) If the evaluative modifier does function as a modifier, then it would be
logical that, particularly in this case, this construction has been integrated
into the already existing premodification zones.

“HCFA is usually applied with the aim of detecting ‘types’ in a population of subjects…one open-ended question that a HCFA can answer is whether the tokens of a grammatical construction can be characterized in terms of one or more types.” (Hilpert 2013: 56-57)
