I made the mistake of googling 11+ vocabulary lists. DC has excellent vocabulary, but the lists and verbal reasoning tests I've found out include words like 'verbose' or 'lithe' or 'elucidate'. DC does read a lot, when we did some verbal reasoning earlier they didn't know the meaning of 'frolic'.
Basically - what do I do? Is this the standard or words really required? Do we look at the twinkle list of words over the next year and I force DC to learn them?!
