I’ve been trying to figure out what exatly it means when someone writes “(read:_____)”. Does anyone know? I can’t find an explanation anywhere online. Also, WHY is it used? Is it “proper”, or just slang? Here’s an example: “…the purpose of this kind of wild character analysis was to establish a psychogenic or functional cause (read: explanation) for Parkinson’s disease…” To me it seems like the writer is trying to better define ‘functional cause’. Why didn’t they just write ‘explanation’ in the first place (if that indeed was the purpse)?
