There are user documentation projects where we are asked to write in American English instead of British English, and generally this is a pretty straightforward exercise for us. However, when I speak at conferences in the USA, delegates sometimes ask me afterwards what I meant by a particular expression. For example, I was recently asked what I meant by “round the houses” and “cheesed off“.
There are a large number of subtle differences between the two versions of English, which has led to a number of very interesting blogs on this subject. In particular, Dr. Lynne Murphy’s Separated by a common language and Professor Ben Yagoda’s Not One-Off Britishisms blogs provide a fascinating insight into how words and expressions gain popularity. The Language Log is another blog worth reading.
If the move to a more conversational approach to technical writing grows in popularity, we may see these differences becoming a bigger factor in localis(z)ing to American or British English.
