Most frequent duplicates
The following is a list of the 172 most common word duplicates (number after word is count of occurrences) extracted from a search of all English Wikipedia articles existing on 21 February 2006.

Most punctuation was automatically removed and so the count is unlikely to be 100% accurate. The count of single letter words is likely to be significantly affected by markup/punctuation removal and these have not been included on the list.

Some of these words occur in a context where duplication is intended, such as for emphasis: please please, blah blah, yadda yadda, very very; where the scientific name of an animal coincides with the common name: Gorilla gorilla, Homo sapiens sapiens; where the genus and subgenus have the same name: Octopus Octopus; or even part of the name, for example: Pago Pago, Dum Dum, Duran Duran, Wagga Wagga, Walla Walla, Chitty Chitty Bang Bang; or a town or city in a county, state or country of the same name: Oxford, Oxfordshire, Cambridge, Cambridgeshire, Luxembourg, Luxembourg.
