A listener wrote in with a project: raise his fifteen-month-old son to speak like an English gentleman, complete with a vocabulary substitution list and a training programme. What follows is a genuinely interesting collision between comedy and developmental linguistics. We dig into Patricia Kuhl's landmark Mandarin work — four weeks of live sessions matching ten months of immersion, while the same content on video or audiotape produced literally nothing — and what that means for screen-based and audio-based language input. Then we take the vocabulary list seriously: the U and non-U distinction from Alan Ross's 1954 paper, the substitutions that survived into modern usage, and the ones that are pure costume. Along the way: sensitive periods for phonetics, why motherese is doing real work, when children start shifting toward their peers' dialect, and why verb diversity in parent input predicts a child's later vocabulary more than accent ever will.
