There is a compendium somewhere that lists the most common misspellings of English on the Internet. Mostly these are attributed to typos and "fingering errors"; but there are a lot of commonly misspelt words. This suggests all human typists follow common usage patterns and so, misspellings are a statistic of these patterns. For instance, I commonly futz the word "quantum", often hurriedly typing "qunatum"; then the word "what" often ends up as "waht". So here are a few examples, with possible semantics attached. "Terminalogy": the study of terminals, particularly the ones that end immediately. "Waht": what happens when you forget your baseball cap - acronym for "without a hat". "Qunatum": an artificial atom, made by atumic scientists. ...anyone have any others?
