An extraordinary long-form piece about a child who'd been born deaf (perhaps of Latino origin, growing up in the streets of a US city) and was then abandoned by his parents. He hadn't learned to speak. As an adult he was given help by a charity (or research group?) who, over the course of years, taught him to speak. There's a moment described in the article when he finally realises that all objects have names, and bursts into tears. When asked to recall how he thought about the world before he learned to speak, he could not describe his cognition.
