Listen up, wannabe bilinguists. I’m going to let you in on a secret: you don’t need Rosetta Stone. Nor do you need adjective flash cards, a pocket-sized phrase book or any teach-yourself course that will make you an expert in pronouncing “the man can run” in the Queen’s English but able to say little else. What you need is to step away from the inanimate and start interacting, and I don’t mean pricey tutorials over Skype. The thought of putting what you’ve learnt into practice can be scary, whether you’re at A1 or C1 stage- it’s fair to compare the feeling to jumping from making coke and menthol rockets to assisting at NASA – but I’m happy to make a bet that it’s the most effective way.
