CT: At present, then, checkers and correctors play a small but useful role in helping people to remove minor errors from their written work. Some systems are just checkers – they flag errors but make no attempt to offer suggestions – and this is often all that is required; if you’ve typed adn for and, you can correct it easily. Most systems, however, do both checking and correcting, so that the word spellchecker usually means a piece of software that both checks the text and offers suggestions for misspelt words. A list of suggestions can occasionally be helpful, especially for people whose spelling is a little weak; not everyone would know, if a checker queried occurence, that it ought to be occurrence. But spellcheckers are still some way short of offering the help that a poor speller wants – the kind of job that a good typist would do.
They miss a fairly high proportion of errors; real-word errors form a substantial minority of spelling errors and most spellcheckers ignore them completely. Their suggestions are often irritatingly inappropriate, frequently including words that are obscure or syntactically out of place. If the misspelling differs from the correct word in certain ways, such as having a different first letter (nowledge, wrankle, eny), or being more than one letter longer or shorter (probly, cort, pollitishion), or having several letters different (payshents, powertree, highdrawlick), the required word may not be in the list of suggestions at all.
