333: Do Nov 6, 2015

'Do' is unique to English and Welsh. In English, the word is used to form questions, negative statements, and for emphasis in positive statements. In other languages, not only is this word, or some equivalent unnecessary, and it is nonexistent in other living languages, except perhaps in the sense of an action. The word is originally from Cornish which is now dead, and had special words for denoting questions, and separating valences.
