Afew years ago, when Anton-ella Sorace visited the European Central Bank in Frankfurt to talk about her research into bilingualism, she was astonished to find the bank’s multinational staff worrying about what should have been one of their families’ principal assets. “They had all kinds of doubts about the benefits of multilingualism for their children; they worried that their children weren’t learning to read or write properly – in any language,” she says. “I found it very instructive.”

The Italian-born University of Edinburgh professor of developmental linguistics should set their minds at rest. Prof Sorace’s research has shown that speaking another language offers not only utilitarian communication ad-van-tages, but also has cognitive benefits. Her message to business is: “Hire more multilingual employees, because these employees can communicate better, have better intercultural sensitivity, are better at co-operating, negotiating, compromising. But they can also think more efficiently.”

Big multinational companies recognise the importance of language skills. McKinsey counts more than 130 languages spoken across the management consultancy, and offers a bursary to those who wish to learn another language before joining. Unilever estimates that up to 80 of the consumer products group’s 100 most senior leaders speak at least two languages. Standard Chartered seeks out bilinguals for its international graduate training scheme.
