Child Genius

The semi-final of the Child Genius competition. Nearly half of the eight remaining competitors will be knocked out today, as only five can make it through to tomorrow's final. To make matters worse, illness threatens to derail one competitor and nerves nearly send another crashing out. Quizmaster extraordinaire Richard Osman presides over today's gruelling language rounds. In the first round, the competitors face fiendishly difficult definitions and anagrams, as their understanding of the English language is stretched to its limit. In the afternoon it's sudden death spelling, where one false move could send even the morning's top scorer home.
