My pet hate is the corruption of the English language but equally annoying is where words seem to change. "Forever" is a classic example. There are instances in English grammar where the use of the word should be broken as in the case of the prayer ending "for ever and ever, Amen" However in most instances it is used as one word. It stands out a mile when reading it in a newspaper article. I assumed it was a typo but it's happening more and more even where the words of a hymn come up on the television screen. Most annoying of all though was where it came up underlined in red as an error on a document I was typing out. If you look up the word in a dictionary it tells you "Also for ever (Ame)" But why the hell should we have to adopt to the American style of speech?
