‘A relieved Obama’ won’t last long de Hoop, Helen and Kemperman, Erica,, 32, 75-87 (2015), doi = https://doi.org/10.1075/avt.32.06hoo, publicationName = John Benjamins, issn = 0929-7332, abstract= Indefinite articles are generally used to introduce new or unfamiliar entities to the discourse. However, in noun phrases such as een opgeluchte Obama ‘a relieved Obama’, the proper noun denotes a familiar individual who does not even have to be new in the discourse. Yet, an indefinite article is used in this construction. We have conducted a corpus study in written Dutch and a production experiment in order to find out the characteristics of this construction as well as its definite counterpart. We will show that the denotation of the adjective plays a crucial role in the semantic composition of the construction, and that preferences for either a definite or an indefinite article correlate with differences in the duration of the state denoted by the adjective. We will use semantic type-theory to account for these findings., language=, type=
