On Radio 4’s The Archers, one of the characters was expecting a baby … Someone described her baby as ‘a Down’s Syndrome baby’ and she insisted she was having ‘a baby with Down’s Syndrome’. Can you see the semantic difference?
At a level of language, we can describe the two structures very differently. The first is a pre-modified noun phrase: the head word ‘baby’ is at the end of the phrase and we therefore first register the condition. The second is a post-modified noun phrase: the noun ‘baby’ comes first with the condition as a qualifier (in the form of a prepositional phrase).
The order of information in a phrase is important because it affects the way we respond. In this case, the character was drawing attention to the fact that her baby would not be defined by her condition – that she was a baby first and that her condition was just one element of who she would be.
