This article provides a constructional (CxG) analysis of N-ADJ compounds in which the noun receives a degree reading (e.g. bullet-straight, Kennedy-handsome). A semantic analysis based on similes and scale matching is provided, and the recent history and increased productivity of the construction are examined in light of data from both the Corpus of Historical American English and a range of present-day corpora. The article introduces new evidence of the increased functional flexibility of both common and proper nouns in English and discusses the ongoing conventionalisation of proper noun degree modifiers in both American English and other varieties of English. The results of the study suggest that the recent introduction of proper noun degree modifiers has been supported by both constructional (semantic) change and macro-trends that have affected English usage more generally.
