If you are looking to conduct business with English speaking companies, particularly those that focus require focus on legal matters or contract terms and conditions, why is it desirable or even necessary to learn day to day conversation about the weather, colours, where you went on holiday, likes and dislikes etc?
There is no doubt that a course in Business English concentrating on providing the tools to, say, negotiate the terms of a contract or review a company balance sheet can be invaluable. However, apart from the fact that the English language is rich in idioms that are used in all walks of life (including business), the ability to form a professional relationship will be greatly enhanced with a more rounded knowledge of vocabulary, grammar and topic awareness.
A client may wish you to clarify ‘the fine print’ or ask you to ‘read between the lines’ because the law can be a ‘grey area’ and a ‘minefield’. It is essential to appreciate what they are asking. At the most basic level, a request to review the terms on page 3 would prove to be problematic if you don’t know what the word ‘page’ means and an obstacle to forging that relationship of trust.
