I recently became aware of an English syntactic construction I hadn’t noticed before. It involves the predicate is crazy, which itself is nothing new, but here the subject of that predicate is, essentially, quoted speech from a second party. I myself am apparently a user of this variant. For example, a friend told me of someone who describes themselves (on an online dating platform) as someone who …likes travel and darts, and I responded, simply, Likes darts is crazy. That is to say, I am making some kind of assertion that the description “likes darts”, or perhaps the speech act of describing oneself as such, is itself a bit odd. Now in this case, the subject is simply the quotation (with the travel and part elided), and while this forms a constituent, a tensed VP, we don’t normally accept them as the subject of predicates. And I suspect constituenthood is not even required. So this is distinct from the ordinary use of is crazy with a nominal subject.
I suspect, though I do not have the means to prove, this is a relatively recent innovation; I hear it from my peers (i.e., those of similar age, not my colleagues at work, who may be older) and students, but not often elsewhere. I also initially thought it might be associated with the Mid-Atlantic but I am no longer so sure.
Your thoughts are welcome.
