A person with an obsession to a particular subject could be labeled what psychologists call a “trait curious” person.
I understand what the underlined part means, but I'm wondering about it from a grammatical point of view. How come such a collocation "trait" +"curious" is possible?
Is it grammatically similar to, say, "type 1" of "type 1 diabetes" ? Any idea?
This appears to be okay, and similar to combinations like: light sensitive, girl/guy shy, etc.
