In Lucy Ellmann’s sharp comic novel Varying Degrees of Hopelessness there is a minor but interesting ambiguity:
Later, she formed an alliance with a man much younger than herself, a man with small feet that didn’t scare her, a man who earned his living by entering supermarket competitions and the occasional raffle.
The question is, what didn’t scare her (she being the narrator’s mother) – the man or his small feet? I don’t think the book mentioned fear of feet elsewhere, so my first inclination was to assume that that in a man with small feet that didn’t scare her referred to the man.
But then why use a man who in the next clause? If the variation is meaningful, and not motivated by whimsy or euphony, etc., we could reasonably assume the fear refers to the feet. But I wouldn’t bet on it.
In a post on animals and pronouns, I summarised as follows: that can refer to things or people, which refers to things but not normally people, and who refers to people (and sometimes animals, or entities that are humanlike or have an implication of personality).
So a man with small feet which didn’t scare her would definitely imply that the feet didn’t scare her, while a man with small feet who didn’t scare her would connect the lack of fear decisively to the man. But that is ambiguous. How would you read it?
