Talk:knock on wood

why is there a UK pronunciation if this is an American idiom? — lexicógrafa | háblame — 02:13, 18 November 2010 (UTC)

If a Brit reads it somewhere, or hears an American say it, he might not be familiar with it, so he looks here for the definition. In case he wishes to say it out loud, he needs the British pronunciation. He would not like to be forced to use the American pronunciation. —Stephen (Talk) 02:59, 18 November 2010 (UTC)
