Below is the list of the 100+ most often misspelled long words (10 letters or more) in the enwiki dump: enwiki-20070206-pages-articles.xml.bz2

The words are sorted first by word form distribution ("d" in the list) then by count ("c" in the list). The 9GB dump file is logically broken into 6314 parts, each 200'000 tokens long (using a special C program I wrote), so the "distribution" number shows in how many of these parts each misspelling is found. In other words the higher the distribution number the more homogeneously distributed each misspelling is throughout the dump file.

means "definately" is misspelled, suggested replacement is "definitely", the letter at position 6 should be changed to "i", the distribution of the misspelled word is 1322, the raw count of the misspelled word is 1495.
 * Example: definately (suggest: 1. definitely (change i 6)) 1322d 1495c

TODO:
Publishing the complete list (or at least much longer) in the near future. The raw enwiki-20070206 file of the misspelled long words (10 letters or more) with suggested replacements contains about 147'000 different misspellings (57'700 with distribution 2 or more), but some percentage are false positives due to imperfections in the half-million English word forms list that I use, mostly due to missing valid word forms (for example "microcontrollers" is reported as a misspelling with a suggested replacement "microcontroller", simply because the plural form "microcontrollers" is not in the English word list). Another reason for false positives are the foreign words that are very close to their English counterparts (example: "Enciclopedia" (Spanish) is reported as a misspelling of Encyclopedia (change y 4) 495d 632c.
