 The word hyperlexia is derived from the Greek terms "hyper" ("over, beyond, overmuch, above measure") and "lexis" ("word").Although hyperlexic children usually learn to read in a non-communicative way, several studies have shown that they can acquire reading comprehension and communicative language after the onset of hyperlexia.They follow a different developmental trajectory relative to neurotypical individuals, with milestones being acquired in a different order.
